| 2 | Characteristics of hydrocarbon accumulation and exploration potential of the northern South China Sea deepwater basins显示文摘Although the huge potential of the northern South China Sea deepwater basins has been proven by a series of discoveries that followed the exploration breakthrough of well LW 3-1-1, recent drilling and other studies have demonstrated the uniqueness and complicated nature of hydrocarbon accumulations of the deepwater basins there. Based on a review of previous work and the latest exploration activities and studies, the purpose of this paper is to discuss the critical controls for hydrocarbon accumulations in the deepwater basins of the northern South China Sea. A terrestrial-marine transitional coal-bearing source rock is proposed to be the primary source rock for the deepwater basins. A marine source rock, which was first identified as contributing to hydro-carbon generation in this region, probably plays a significant role in the deep-and ultra-deep water basins south to the Pearl River Mouth and Qingdongnan basins. The shelf margin delta depositional systems in the Baiyun Sag, sourced from the Pearl River, are currently primary exploration targets in the deepwater part of the Pearl River Mouth Basin, whereas the western Red River delta-ic-submarine fan depositional systems, initially proven by drilling, are the possible major exploration reservoirs in the Qing-dongnan deepwater areas. Current deepwater exploration targets at the large-sized structural traps and deep and ultra-deep areas in the south of the Pearl River Mouth and Qingdongnan basins will be the future exploration focus. Deepwater exploration activities and relevant fundamental studies, supporting and promoting each other, are of great importance to the national energy supply of China, the basic regional studies of the South China Sea, advancements in technology, and development of related deepwater industries, and will safeguard national sovereignty and territorial integrity. | ZHU WeiLin ZHONG Kai LI YouChuan XU Qiang FANG DianYong | 2012 | Chinese Science Bulletin2012，57，24： | 48 |

| 4 | Controlling factors on the submarine canyon system: A case study of the Central Canyon System in the Qiongdongnan Basin, northern South China Sea显示文摘Based on an integrated analysis of high-resolution 2D/3D seismic data and drilling results, this study analyzes the tectonicsedimentary evolution of the Qiongdongnan Basin(QDNB) since the late Miocene, and discusses the controlling factors on the formation and development of the Central Canyon System(CCS). The sediment failures caused by the relative sea level falling might have discharged deposits from the slope to the canyon. The two suits of the infillings, i.e., turbidites and mass transport complex(MTC), were derived from the northwestern source and northern source, respectively. The sediment supplies, which differ significantly among different areas, might have led to the variations observed in the internal architectures. Tectonic transformation around 11.6 Ma had provided the tectonic setting for the CCS and formed an axial sub-basin in the central part of the Changchang Depression, which could be called the rudiment of the CCS. The tectonic activity of the Red River Fault(RRF) at about 5.7 Ma might have strengthened the hydrodynamics of the deposits at the junction of the Yinggehai Basin(YGHB) and the QDNB to trigger a high-energy turbidity current. The MTC from the northern continental slope system might have been constrained by the Southern Uplift, functioning as a barrier for the infillings of the CCS. Thanks to a sufficient sediment supply during the Holocene period and the paleo-seafloor morphology, the relief of modern central canyon with the starving landform in the eastern Changchang Depression might have been accentuated by deposition of sediments and vertical growth along the canyon flanks, where collapse deposits were widely developed. Corresponding to the segmentation of the CCS, the forming mechanisms of the canyon between the three segments would be different. The turbidite channel in the head area had likely been triggered by the abundant sediment supply from the northwestern source together with the fault activity at about 5.7 Ma of the RRF. The formation and evolution of the canyon in the western segment were caused by combined effects of the turbidite channel from the northwestern source, the MTC from the northern continental slope, and the paleo-seafloor geomorphology. In the eastern segment, the canyon was constrained by the tectonic transformation occurring at approximately 11.6 Ma and the insufficient sediment supply from the wide-gentle slope. | SU Ming ZHANG Cheng XIE XiNong WANG ZhenFeng JIANG Tao HE YunLong ZHANG CuiMei | 2014 | Science China Earth Sciences2014，57，10： | 21 |
| 5 | 琼东南盆地乐东、陵水凹陷中新统岩性地层圈闭成藏条件显示文摘区域构造-沉积背景分析及大面积三维地震资料处理结果表明,渐新世早期受红河断裂走滑侧翼拉分作用,琼东南盆地乐东、陵水凹陷形成了大规模的崖城组海陆过渡—半封闭浅海相烃源岩。该区主要勘探目的层系为中新统深水沉积储层,其中,上中新统黄流组轴向水道分为海南隆起水系提供主要物源的早期水道和昆嵩隆起秋盆河提供主要物源的晚期水道,2期水道砂岩具有不同的空间展布规律和沉积形态;中中新统梅山组坡控海底扇受物源和古地形影响发育斜坡水道型、盆底扇型和底流改造型等3种沉积样式,不同沉积样式控制不同的储层沉积和物性特征。这2种类型深水储集体在沉积和差异沉降作用下形成4种类型岩性地层圈闭,其下伏深部地层由于水热和生烃增压作用而形成区域范围的裂隙网络,从而沟通了深部烃源岩地层,使天然气在超压和浮力作用下运移到中新统岩性地层圈闭富集成藏。 | 范彩伟 李绪深 刘昆 谭建财 宋鹏 李虎 | 2016 | 中国海上油气2016，28，2： | 19 |
| 6 | 古红河沉积物稀土元素特征及其物源指示意义显示文摘莺歌海盆地内的大量沉积物是验证与青藏高原隆升有关的河流流域变化争论的理想材料.因此,对南海西北部莺歌海盆地6口井沉积物样品进行了稀土元素分析,结果发现,位于盆地中央轴部位的N4、N5及N6井沉积物自晚渐新世到更新世具Eu元素正异常的特征,显示其母岩应为红河流域内大量基性-超基性变质岩和火山岩;位于盆地东侧斜坡带的N1和N2井沉积物则受控于以Eu元素负异常为标志的海南岛;位于盆地东南侧的N3井沉积物晚渐新世明显受到基性物源的影响,使Eu元素呈现正异常的特征,到上新世该井沉积物主要受控于海南岛物源.越南中北部马江断裂带中古生界变质岩区以及红河流域的变质岩区为该地区提供了大量基性沉积物,造成该地区沉积物具Eu元素正异常的特征.可以认为,红河源区从晚渐新世一直到更新世时期流域内母岩类型基本保持稳定,没有大的流域母岩类型突变事件发生.因此,如果红河在其演化历史上发生过流域面积袭夺事件,其时间也只能在晚渐新世之前或更新世之后. | 赵梦 邵磊 梁建设 乔培军 向绪洪 | 2013 | 地球科学(中国地质大学学报)2013，38，S1： | 18 |

| 9 | 三沙海底峡谷识别与地貌特征分析显示文摘三沙海底峡谷是连接西沙碳酸盐台地与南海西北次海盆的深水海底峡谷,起源于永兴岛和东岛之间的浅水区域,输送了大量碳酸盐碎屑到西北次海盆。三沙海底峡谷是迄今为止发现的南海最大碳酸盐型海底峡谷。海底峡谷的横断面呈现V、U字形,可以分为峡谷外侧、斜坡和谷底3个部分。峡谷外侧平缓、两侧斜坡陡峭、谷底平缓。沿着峡谷走向,可以分为上游、中游和下游3部分。上游部分坡度较陡、坡度变化较大,环礁周边的水道和海底滑坡体系是源区的碎屑物质搬运通道;中-下游部分坡度平缓、坡度变化小,主要以碎屑物质的搬运为主,汇入两侧斜坡上的侵蚀、坍塌形成的碎屑,在西北次海盆形成了喇叭状的入海盆口。通过三沙海底峡谷的研究,有助于揭示岛礁与海盆之间的沉积物输送、海底不稳定性等基础科学问题,为碳酸盐岩油气储层预测、岛礁生态旅游开发提供理论基础。 | 李学杰 王大伟 吴时国 王微微 刘刚 | 2017 | 海洋地质与第四纪地质2017，37，3： | 12 |
| 10 | 琼东南盆地深水区新近系海底扇沉积特征与资源潜力显示文摘综合利用钻井、岩心、薄片及分析化验资料研究了琼东南盆地深水区新近系海底扇沉积特征,并利用最新的三维地震资料,通过井震精细标定、多属性融合技术、方差体切片、三维地貌砂体镂空等综合技术手段,精细刻画了海底扇砂体的空间分布特征。研究结果表明,深水区新近系海底扇是由陆架区的砂体滑塌并二次搬运形成,形成过程具有多期次性。受不同物源的影响,海底扇岩性和物性存在较大的差异。海底扇岩性及沉积构造具有砂质滑塌、碎屑流、浊流和深水底流改造的特征。海底扇的沉积微相、厚度、砂泥比和砂泥岩空间配置关系直接控制了地震振幅反射强度和频率的变化。砂体纵向叠置,横向连片,并被后期泥质水道切割分块形成多个岩性圈闭。综合分析认为,深水区海底扇砂体发育区烃源条件优越,储盖配置关系和圈闭条件良好,具备形成大中型岩性油气藏的有利条件,具有较大的油气勘探潜力。 | 左倩媚 张道军 王亚辉 李伟 陈杨 何小胡 党亚云 | 2016 | 海洋学报2016，38，11： | 11 |
| 11 | A heavy mineral viewpoint on sediment provenance and environment in the Qiongdongnan Basin显示文摘Based on heavy mineral data in core samples from eleven drillings, supplemented by paleontological, element geochemical and seismic data, the evolution of sediment provenance and environment in the Qiongdongnan Basin(QDNB) was analysed. The results show that the basement in the QDNB was predominantly composed of terrigenous sediments. Since the Oligocene the QDNB has gradually undergone transgressions and evolution processes in sedimentary environment from terrestrial-marine transitional to littoral-neritic, neritic, and bathyal roughly. The water depth showed a gradually increasing trend and was generally greater in the southern region than that in the northern region in the same time. With changes in sedimentary environment, provenances of the strata(from the Yacheng Formation to the Yinggehai Formation) showed principal characteristics of multisources, evolving from autochthonous source, short source to distant source step by step. During the Early Oligocene, the sediments were mainly proximal basaltic pyroclastic source and adjacent terrigenous clastic source, afterwards were becoming distant terrigenous clastic sources, including Hainan Island on the north,Yongle Uplift on the south, Shenhu Uplift on the northeast, the Red River System on the northwest and Indochina Peninsula on the southwest, or even a wider region. The Hainan Island provenance began to develop during the Early Oligocene and has become a main provenance in the QDNB since the Middle Miocene. The provenances from Yongle Uplift and Shenhu Uplift most developed from the Late Oligocene to the Early Miocene and gradually subsided during the Middle Miocene. During the Late Miocene, as a main source of sediments filled in the central canyon, the Red River System provenance added to the QDNB massively, whose impact terminated at the end of the Pliocene. The western Yinggehai Basin(YGHB) provenance derived from Indochina Peninsula had developed from the Pliocene on to the Pleistocene. In addition, the material contribution of marine authigenous source to the basin(especially to the southern region) could not be ignored. | LIU Xiaofeng ZHANG Daojun ZHAI Shikui LIU Xinyu CHEN Hongyan LUO Wei LI Na XIU Chun | 2015 | Acta Oceanologica Sinica2015，34，4： | 10 |

| 14 | 金沙江寨子村古堰塞湖沉积年代研究显示文摘近年来,金沙江金江街寨子村古堰塞湖沉积受到学术界的目益关注。总体来说存在两种认识,一种认为这套沉积物是早更新世昔格达古湖沉积(昔格达组)的一部分,它可以反映古金沙江的袭夺演化历史,另一种观点认为它是一套堰塞湖沉积,具有沿河分布的特点,且存在残存的堵江堰塞滑坡坝体。然而这些认识目前都缺少年代学数据的支撑。为此,我们采用光释光(OSL)测年技术,选择地层界线出露相对完整的沿江小学剖面(26°14′54.034″N,100°25′32.114″E)系统地进行了地层学、年代学研究。结果发现,寨子村古堰塞湖沉积整体覆盖在金沙江第二级阶地上,在靠近残余堰塞坝体处厚度较大,逐渐向上游尖灭。其顶部OSL年龄为93kaB.P.,底部为110kaB.P.。堰塞湖沉积之上有约2m厚的黄土堆积,其下部发育一层古土壤,古土壤顶部OSL年代为73ka13.P.,表明寨子村古堰塞湖沉积形成于晚更新世,不是先前推测的早更新世,与学术界广泛认为的昔格达组不属于同一时代地层,因此难以记录早更新世古金沙江的袭夺演化历史。 | 朱正峰 苏怀 董铭 明庆忠 史正涛 | 2018 | 第四纪研究2018，38，1： | 8 |

| 16 | Evolution of deepwater sedimentary environments and its implication for hydrocarbon exploration in Qiongdongnan Basin, northwestern South China Sea显示文摘Over the past several years, a number of hydrocarbon reservoirs have been discovered in the deepwater area of Qiongdongnan Basin, northwestern South China Sea. These oil/gas fields demonstrate that the evolution of the deepwater sedimentary environment are controlling the formation and distribution of large-scale clastic reservoirs. Integration between seismic and borehole data were necessary to best clarify the distribution and quality of these deepwater reservoirs. Geochemical and paleobiological evidence from discrete samples was also applied to document specific information regarding the sedimentary environment. Results show that the Qiongdongnan Basin has existed as a thriving marine environment since Oligocene, when several rifting depressions developed throughout the entire Qiongdongnan Basin. Triggered by the faults activities, several distinct provenances supplied the coarse sediments, transporting and depositing them in deep parts of the rifting depressions. A fan delta system then formed nearby the source in the deeper area of these rifting depressions. The sedimentary environment of Qiongdongnan gradiationally became deepwater since early Miocene.Consequently, abundances of sediments were transported from Hainan Island and Southern Uplift, and then sunk into the basin center. The submarine fans revealed by many boreholes in this area verified them as good reservoir. Because the area reached its lowest sea level at late Miocene and the Southern Uplift subsidenced under sea level, not providing any sediment, so that the carbonate mesa and biorhythms characteristic of this area also developed during this period. In the west part of Qiongdongnan Basin, sediments transported from Vietnam increased in response to the Tibetan Uplift. Consequently, a central canyon developed along the center of Qiongdongnan Basin, which has been confirmed by several boreholes as a favorable hydrocarbon reservoir. The clarification of the deepwater sedimentary environment's evolution is potentially highly beneficial to future hydrocarbon exploration in the deepwater area of Qiongdongnan Basin. | WANG Zhenfeng JIANG Tao ZHANG Daojun WANG Yahui ZUO Qianmei HE Weijun | 2015 | Acta Oceanologica Sinica2015，34，4： | 6 |
| 17 | Coherent variations of the obliquity components in global ice volume and ocean carbon reservoir over the past 5 Ma显示文摘The Milankovi theory stresses that the summer insolation in the high northern latitudes that is dominated by the precession cycle controls the glacial/interglacial cycles in global climate change.If the climate system responds linearly to the external insolation forcing,the precession cycle of 23 or 19 ka should dominate the variations in the climatic proxy records.I performed spectral and evolutive cross spectral analyses on the high resolution benthic 18O and 13C records from the South China Sea and the North Atlantic,the proxies of global ice volume and ocean carbon reservoir respectively.I found that the obliquity instead of the eccentricity or the precession is the most marked cycle in the global ice volume and ocean carbon reservoir variations over the past 5 Ma.The analysis further reveals that only at the obliquity band instead of the eccentricity or the precession band does the global ice volume and ocean carbon reservoir display consistently high coherency and stable phase relationship over the past 5 Ma.The consistently positive or near-zero phases of the benthic 18O relative to the benthic13C at the obliquity band suggest that the global carbon cycle is involved in the polar ice sheet growth as an important internal feedback,not a determinative driving factor.The obliquity instead of the precession or the eccentricity takes the dominant role of driving the global climate change during the Pliocene and Pleistocene. | TIAN Jun | 2013 | Science China Earth Sciences2013，56，12： | 4 |
| 18 | 南海南-北陆缘盆地地层沉积发育特征及其对油气成藏的差异性控制显示文摘南海作为西太平洋最大的边缘海,油气资源丰富,油气赋存规律的南北差异性大。本文在系统梳理南海中—新生代地层、沉积相发育特征的基础上,对南海南北典型含油气盆地的石油地质条件进行了对比分析。结果认为南海打开过程对古南海沉积地层的改造,使得现有残余地层南北分离,主要分布于北部的珠江口盆地—台西南盆地和南部的礼乐盆地中,推测发育“自生自储”、“新生古储”或“古生新储”的中—新生界油气成藏模式。南海新生代油气藏在“北张、南挤”的构造应力背景下,古近纪以来的古水系控制了大型碎屑岩油气藏的分布;区域构造运动和海平面变化控制了中新世碳酸盐岩油气藏的发育;早新生代以来的古地貌控制的深水峡谷、深海扇、扇三角洲沉积体系孕育了潜在深水油气藏。总之,南海南北地层沉积各有特色,油气成藏条件各有优势,但均有良好的油气勘探前景,本文以期为未来南海油气勘探战略部署和选区提供参考。 | 熊量莉 杨楚鹏 吴峧岐 高红芳 姚永坚 李学杰 朱雪影 程子华 | 2020 | 中国地质2020，47，5： | 4 |

| 20 | CFD simulation on the generation of turbidites in deepwater areas: a case study of turbidity current processes in Qiongdongnan Basin, northern South China Sea显示文摘Turbidity currents represent a major agent for sediment transport in lakes, seas and oceans. In particular, they formulate the most significant clastic accumulations in the deep sea, which become many of the world's most important hydrocarbon reservoirs. Several boreholes in the Qiongdongnan Basin, the northwestern South China Sea, have recently revealed turbidity current deposits as significant hydrocarbon reservoirs. However, there are some arguments for the potential provenances. To solve this problem, it is essential to delineate their sedimentary processes as well as to evaluate their qualities as reservoir. Numerical simulations have been developed rapidly over the last several years, offering insights into turbidity current behaviors, as geologically significant turbidity currents are difficult to directly investigate due to their large scale and often destructive nature. Combined with the interpretation of the turbidity system based on highresolution 3D seismic data, the paleotophography is acquired via a back-stripping seismic profile integrated with a borehole, i.e., Well A, in the western Qiongdongnan Basin; then a numerical model is built on the basis of this back-stripped profile. After defining the various turbidity current initial boundary conditions, including grain size, velocity and sediment concentration, the structures and behaviors of turbidity currents are investigated via numerical simulation software ANSYS FLUENT. Finally, the simulated turbidity deposits are compared with the interpreted sedimentary bodies based on 3D seismic data and the potential provenances of the revealed turbidites by Well A are discussed in details. The simulation results indicate that a sedimentary body develops far away from its source with an average grain size of 0.1 mm, i.e., sand-size sediment. Taking into account the location and orientation of the simulated seismic line, the consistence between normal forward simulation results and the revealed cores in Well A indicates that the turbidites should have been transported from Vietnam instead of Hainan Island. This interpretation has also been verified by the planar maps of sedimentary systems based on integration of boreholes and seismic data. The identification of the turbidity provenance will benefit the evaluation of extensively distributed submarine fans for hydrocarbon exploration in the deepwater areas. | JIANG Tao ZHANG Yingzhao TANG Sulin ZHANG Daojun ZUO Qianmei LIN Weiren WANG Yahui SUN Hui WANG Bo | 2014 | Acta Oceanologica Sinica2014，33，12： | 3 |
