| 1 | Discovery and Significance of High CH_4 Primary Fluid Inclusions in Reservoir Volcanic Rocks of the Songliao Basin,NE China显示文摘Comparing compositions of the fluid inclusions in volcanic rocks to the contents and isotopes of the gases in corresponding volcanic reservoirs using microthermometry, Raman microspectroscopy and mass spectrum analysis, we found that: (1) up to 82 mole% methane exists in the primary inclusions hosted in the reservoir volcanic rocks; (2) high CH4 inclusions recognized in the volcanic rocks correspond to CH4-bearing CO2 reservoirs that are rich in helium and with a high 3He/4He ratio and which show reversed order of δ 13C in alkane; (3) in gas reservoirs of such abiotic methane (>80%) and a mix of CH4 and CO2, the enclosed content of CH4 in the volcanic inclusions is usually below 42 mole%, and the reversed order of δ 13C in alkane is sometimes irregular in the corresponding gas pools; (4) a glassy inclusion with a homogeneous temperature over 900°C also contains a small portion of CH4 although predominantly CO2. This affinity between gas pool and content of inclusion in the same volcanic reservoirs demonstrates that magma-originated gases, both CH4 and CO2, have contributed significantly to the corresponding gas pools and that the assumed hydrocarbon budget of the bulk earth might be much larger than conventionally supposed. | WANG Pujun HOU Qijun WANG Keyong CHEN Shumin CHENG Rihui LIU Wanzhu LI Quanlin | 2007 | Acta Geologica Sinica(English Edition)2007，81，1： | 14 |
| 2 | Weathered and Volcanic Provenance-Sedimentary System and Its Influence on Reservoir Quality in the East of the Eastern Depression, the North Yellow Sea Basin显示文摘Seismic stratigraphy, core logging and the data from cores are used to identify the development and evolution of the east provenance-sedimentary system and to analyze its influence on the quality of reservoirs in the eastern depression of the North Yellow Sea Basin. The eastern provenance-sedimentary system is a fan delta(delta) and subaqueous fan sedimentary system with volcanic provenance. Its evolution is closely related to internal uplift and coeval volcanic activity. During faulting and volcanic activity, an internal uplift gradually formed and the eastern provenance-sedimentary system began to develop. Clastic materials from the weathered uplift and volcanic activity were the main sources of sediment and were deposited in the Middle Jurassic to the Early Cretaceous. A subaqueous fan sedimentary system developed in the Middle Jurassic, a deltaic to subaqueous fan sedimentary system developed in the Late Jurassic, and a fan delta to subaqueous fan sedimentary system developed in the Early Cretaceous. The volcaniclastic detritus was mainly composed of acidic materials with a small amount of intermediate materials. The reservoir in the eastern sedimentary system is a type of tight sandstone with ultra-low porosity and very low permeability due to the influence of volcanism and diagenesis. The reservoir quality is worse than those of the northern and the western sedimentary systems. However, the high volume of volcanic materials and deep-marine sedimentary conditions resulted in good-quality hydrocarbon source rocks that ensures the exploration potential in the eastern sedimentary system reservoir. | Dan Gao Rihui Cheng Yanjie Shen Liaoliang Wang Xiaoqiang Hu | 2018 | Journal of Earth Science2018，29，2： | 6 |
| 3 | High resolution continuous sedimentary records of Upper Cretaceous obtained from the continental drilling(SK-1) borehole in Songliao Basin:Sifangtai and Mingshui Formations显示文摘The Sifangtai and Mingshui formations were continuously cored in the SK-1 n borehole(China Cretaceous Continental Scientific Drilling-SongKe1-the north borehole).The core is 767.96 m long,and the recovery is 94.7%.The ages of the formations range from middle Campanian to Danian.The sequence and process of lithology-lithofacies and cyclic stratigraphy were described in detail.Eight litho-types compose the Sifangtai Formation,and 15 litho-types compose the Mingshui Formation.Deposition was predominantly in meandering river and lacustrine environments,including 10 microfacies in the Sifangtai Formation and 15 microfacies in the Mingshui Formation.The complete sequence is composed of 535 m-scale cycles(sixth-order cycle),152 fifth-order cycles,42 fourth-order cycles and five third-order cycles.The centimeter-scale description of the section revealed some previously unknown horizons such as a special type of mudstone,marl,volcanic ash and favorable sand reservoirs in the formations.The new-found evidence is very important for the interpretation of the evolution of the basin,conditions such as lake oxic events,the K/Pg boundary,tectonism in the late sag basin stage,and the reservoir-cap rock assemblages in the shallow stratigraphy. | Guodong Wang Rihui Cheng Pujun Wang Youfeng Gao Chengshan Wang Yanguang Ren Qinghua Huang | 2015 | Geoscience Frontiers2015，6，6： | 5 |

| 5 | The Sequence Architecture of Volcanic Basin Fillings-An Example From Xujiaweizi Faulted Depression In Songliao Basin显示文摘The basin filling geometric pattern of volcanic eruptive rocks depends on both of the eruptive locations in a basin and structural styles of fault terraces. It is divided into three types by eruptive locations and occurrences of eruptive rocks, including the pattern of eruption along fault and occurrence (PEAFO), the pattern of eruption on footwall of a fault and occurrence (PEOFO) and the pattern of eruption on hangingwall of fault and occurrence (PEOHO) in Xujiaweizi fault depression of Songliao basin, Northeast of China. Those basin filling patterns of volcanic eruptive rocks are of specific geometric characteristics controlling or affecting sedimentation, geometry of sedimentary body and sequence architecture during a sequence evolution. The study shows that the volcanic rocks developed at different stages of lowstand, transgressive and highstand can give different controls or affects on the sequence architecture. | CHENG Rihui, LIU Wanzhu, SHAN Xuanlong, WANG Pujun (Faculty of Earth Sciences at Jilin University, Changchun, 130061, P.R.China) CHEN Shumin and QU Yongbao (Daqing Petroleum Bureau Prospecting and Exploration Institute, Daqing, 163712, P.R.China) | 2001 | Global Geology2001，6，2： | 3 |
| 6 | RESPONSE OF TRIASSIC SEQUENCE STRATIGRAPHY OF LOWER YANGTZE TO THE COLLISION BETWEEN THE YANGTZE PLATE AND THE NORTH CHINA PLATE显示文摘The characteristics of the Triassic sequences developed in the Lower Yangtze area display some great changes in both environment and climate. The change of environment was a transition from marine to continent via alternating environments. The change of climate was a transition from tropic (torrid) to warm and wet climate via subtropic dry climate. The type variations of the sequences were from the marine sequences to the continental sequences, corresponding to the changes of environments and climates. Sequence 1 is a type II of sequence of mixed clastic and carbonate sediments; sequence 2 is a type I of sequence of carbonate platform; sequence 3 is a type I of sequence of carbonate tidal flat-salt lagoon, sequence 4 is a type II of sequence of lacustrine within marine layers, and sequence 5 is a sequence of lacustrine-swamp. The development, distribution and preservation of those sequences reveal the tectonic controls and their changes in the background. The collision between the Yangtze plate and the North China plate was a great geological event in the geological history, but the timing of the collision is still disputed. However, the characteristics of Triassic sequence stratigraphy and sea level changes in the Lower Yangtze area responded to this collision. The collision started at the beginning of middle Triassic and the great regression in the Lower Yangtze area started 22Ma earlier than those in the world. The tectonic conditions occurred before and during the collision controlled the development of sequences and type changes. | CHENG Rihui WANG Pujun LIU Wanzhu TANG Huafeng BAI Yunfeng KONG Qingying SONG Weihai | 2005 | Geotectonica et Metallogenia2005，29，2： | 1 |
| 7 | Deep Processes of Basin Evolution:A Case Study of the Southern Songliao Basin and Adjacent Area,NE China in Mesozoic-Cenozoic显示文摘In south of the Songliao Basin and adjacent area of NE China, there are several high conductive layers in crust and upper mantle. Those layers are interpreted as detachment and rheology, which represent some features of lithosphere, asthenosphere and Moho, and related to the crust-mantle structure of the continent in the study area. The differences of the crust-mantle structures in different places in the study area reflect the differences in the movement and evolution of asthenosphere, lithosphere and crust. The differences can be summarized as follows. (1) Along the south profile of MT, the buried depth of the surface of Moho is 31 ~34 km beneath the Liaohe Basin and 35~37 km beneath the west Liaoning area. Along the north profile of MT, the buried depth of Moho is 32~33 km beneath Changtu area and 36~37 km beneath Kailu area in southern Songliao Basin. The buried depth beneath the central of the Songliao Basin is 29 km.(2) The difference of thickness of lithosphere exists in the south area and the north area of Chifeng-Kaiyuan fault. The thickness of lithosphere is about 65~120 km in the south of the fault, thickening from east to west. The top surface of asthenosphere is highly uplifted in the Liaohe Basin and the highest point is about 65 km in buried depth. The thickness of lithosphere in the north of the fault is about 60~65 km, thinner about 25 km than that in the south of the fault (West Liaoning). Deep processes such as upwelling of mantle thermal flow, extension of lithosphere, underplating, and thinning and subsidence of crust, evidenced from the crust-mantle structures were the direct forces of the basin formation in the study area during the Mesozoic-Cenozoic. | Rihui Cheng Dongpo Wang Linfu Xue | 2003 | Global Geology2003，8，1： | 0 |
| 8 | New Discovery of Upper Crustal High-and Low-Velocity Belts and High-Velocity Core in the Tarim Basin显示文摘The Tarim Basin is the biggest oil-and gas-bearing basin in China,which has undergone long-term and complicated evolutionary history.During each evolutional stage and in different sub-basins in the same stage,the Tarim Basin has different proto-types,and it is thus named a composite and superimposed basin.A study on the basement nature of such a complex but significant to the national oil and gas strategy basin is of great significance(Huang Chenjun et al.,2017).Based on earthquake data,detailed velocity structure of deep basin can be obtained in order to research the basement nature. | WANG Tengfei JIN Zhenkui YU Xiaoxia CHENG Rihui SONG Xue YANG Baoju LI Shuo SHI Shuting | 2019 | Acta Geologica Sinica(English Edition)2019，93，1： | 0 |
| 9 | Lacustrine high resolution sequence records from Upper Cretaceous Nenjiang Formation in Songliao Basin显示文摘The Nenjiang Formation was continuously cored in the SK-1 borehole(China Cretaceous Continental Scientific Drilling Project-SongKe1well).Over 95.7%recovery rate,the obtained continuous core is 827.6 m in length,covering the geological age ranges from late Santonian to middle Campanian.This is the most complete and continuous sedimentary deposits in the Songliao basin till now.Here we systematically presented the lithological results of the observation of the cores in 2--5 cm thickness scale at the drilling spot,and the analysis on lithofacies and sedimentary sequence,cyclic stratigraphy.13 types of sedimentary rocks deposited mainly in lacustrine,delta and fluvial environments were found in the Nenjiang Fromation,and they were subdivided into 19 microfacies including dolomite,marl,argillaceous limestone,turbidite,mudstone of still water,volcanic ash,channel-lag deposit,point bar,natural levee,crevasse splay,crevasse channel,floodplain,flood lake,distributary mouth bar,subaqueous distributary channels,subaqueous natural levee,subaqueous inter-distributary bay,distal bar and adjacent shore sand bar.The whole sedimentary column is composed of 630 sixth-order depositional cycles in the meter-scale,which can be further organized in 148 fifth-order depositional cycles,38 fourth-order depositional cycles and 5 third-order depositional cycles.Meticulous depiction(centimeter level)of the whole Formation provides an approach to study its sedimentary process with high precision.The centimeter-scale description of the sequent core presented some previously unidentified dolomite and volcanic ash layers.The cyclostratigraphy of the Nenjiang Formation was controlled by Milankovitch cycled,which is helpful to discover the climatic changes of the late Santonian to the middle Campanian in Songliao Basin.In addition,the detailed description of the sequent section is significant for the upcoming oil and gas exploration in the Songliao Basin if regarding the new type of oil/gas systems. | GAO Youfeng JIAO Yuhui WANG Pujun CHENG Rihui WANG Guodong | 2020 | Global Geology2020，23，1： | 0 |
| 10 | Structural Control of Sand Bodies and Deep Exploration for Oil and Gas显示文摘The structural styles can be used to analyses and predict developments and distributions of sand bodies in a rift basin. The dynamic process of faulting and sedimentation can be expressed as follow: the basin topography controlled by fault activity can control water dynamics; which in turn affect the transport and sedimentation of sediments. The corresponding analysis between structural styles and sand depositional types includes the following aspects: (1) in section, the corresponding between development of fault terraces and sand depositional types; (2) in plane, the relationship between faults' association and distributions of sand bodies. There are four types of terrace styles to be identified. They are Steep Slope Single Fault Terrace (SSSFT), Steep Slope Multiple Fault Terrace (SSMFT), Gentle Slope (GS) and Gentle Slope Multiple Fault Terrace (GSMFT), which also can be divided into six subtypes by the timing of the faults activities and the directions of their activity migrations (basinward and landward or marginward). They correspond to the following sand depositions such as alluvial fan, fan delta and turbidite fan etc.. The analysis of structure-sedimentation is a discussion on the rank Ⅲ sequence evolution under the condition of pulsing or episodic fault activities. It has been recognized four plane fault associations such as the comb, the broom, the fork and the fault-fold association as well as the corresponding sand distributions. Structural-sedimentary models above mentioned are significant for the deep oil and gas exploration when lacking of the drill data. It may reduce multiple resolutions in the interpretation of seismic-sedimentary facies and promote sand predictions through the constraints of the structural styles of the basin units. The structural-sedimentary pattern can be used as a geological model in oil and gas exploration in the rift basins. | Cheng Rihui Lin Changsong Zheng Herong | 2002 | Global Geology2002，7，2： | 0 |
| 11 | Correspondence Between Astronomical Periods and Sedimentary Cycles显示文摘It is shown from detailed study that there are some genetic relationships between outer events of celestial bodies and inner geological events of the earth, such as some kinds of correspondences between astronomical periods and sedimentary cycles. The time spans of movement periods of the solar.system around the center of the galaxy and cross the plain of the galaxy, the periods of the earth orbit (Milankovitch period) and periods of sunspot are coincided with that of respective sedimentary cycles. It is suggested that the gravity and magnetic changes of the earth leading up to the global climatic and sea level changes are the dynamics of sedimentary cycles. | Cheng Rihui You Haitao | 2000 | Global Geology2000，5，2： | 0 |
