| 1 | Formation and destruction processes of upper Sinian oil-gas pools in the Dingshan-Lintanchang structural belt, southeast Sichuan Basin, China显示文摘The lower Cambrian Niutitang Formation hydrocarbon source rocks at the Dingshan-Lintanchang structure in the southeast Sichuan Basin were of medium-good quality with two excellent hydrocarbon-generating centers developed in the periphery areas, with a possibility of forming a medium to large-sized oil-gas field. Good reservoir rocks were the upper Sinian (Dengying Formation) dolomites. The mudstone in the lower Cambrian Niutitang Formation with a good sealing capacity was the cap rock. The widely occurring bitumen in the Dengying Formation indicates that a paleo oil pool was once formed in the study area. The first stage of paleo oil pool formation was maturation of the lower Cambrian source rocks during the late Ordovician. Hydrocarbon generation from the lower Cambrian source rocks stopped due to the Devonian-Carboniferous uplifting. The lower Cambrian source rocks then restarted generation of large quantities of hydrocarbons after deposition of the middle Permian sediments. This was the second stage of the paleo oil pool formation. The oil in the paleo oil pool began to crack during the late Triassic and a paleo gas pool was formed. This paleo gas pool was destroyed during the Yanshan-Himalayan folding, uplifting and denudation. Bitumen can be widely seen in the Dengying Formation in wells and outcrops in the Sichuan Basin and its periphery areas. This provides strong evidence that the Dengying Formation in the Sichuan Basin and its periphery areas was once an ultra-large structural-lithologic oil-gas field, which was damaged during the Yanshan-Himalayan period. | Liu Shugen Zhang Zhijing Huang Wenming Wang Guozhi Sun Wei Xu Guosheng Yuan Haifeng Zhang Changjun Deng Bin | 2010 | Petroleum Science2010，7，3： | 20 |
| 2 | Formation and evolution of Sinian oil and gas pools in typical structures, Sichuan Basin, China显示文摘The only major breakthrough in the exploration of the Sinian of the Sichuan Basin has been the Weiyuan gas field. Taking the typical structures in the Sichuan Basin as examples, an apatite fission track simulation was applied to constrain the thermal evolutionary history of the source rocks in this study. Combined with trap formation and evolution, the formation, destruction, and accumulation history of the Sinian reservoirs were analyzed from a dynamic perspective. The Sinian reservoirs underwent several primary stages: the paleo-reservoir formation and destruction in the late Silurian, hydrocarbon recharge in the Permian-Triassic, the cracking of oil to gas and dissolved-gas in the late Triassic-Mid-Late Jurassic, and the exsolution and accumulation of dissolved-gas as a result of episodic uplift since the Late Cretaceous. The exsolution process of dissolved-gas is of great significance to the accumulation of natural gas. The formation of the Weiyuan gas field is also related to this process. The Sinian in the Sichuan Basin has a broad exploration prospect, and exploration targets focused on the Leshan-Longnüsi Paleo-uplift tectonic zone with weak influences on potential hydrocarbon reservoirs from the late tectonism and transformation. | Yuan Haifeng Liang Jiaju Gong Deyu Xu Guosheng Liu Shugen Wang Guozhi | 2012 | Petroleum Science2012，9，2： | 7 |

| 8 | Effect of Seed Preservation Technique on the Germination of Artemisia annua Seeds显示文摘[Objectives] To explore the techniques of long-term preservation of Artemisia annua. [Methods] Using different storage methods,germination test and statistical analysis,the effect on seed germination of Artemisia annua was studied. [Results] In cold storage,the envelope preservation had the best effect,while the self-sealing bag had the worst effect; under freezing at low temperatures,the hop-pocket preservation had the best effect,while the self-sealing bag effect had the worst effect. In short,under different storage methods,the self-sealing bag had the worst packaging effect,indicating that the ventilation property of self-sealing bag was poor,affecting the seed breathing,thereby affecting the vitality of the seed,and shortening the life of the seed. [Conclusions]The cold storage envelope packaging was the most appropriate way of storage for Artemisia annua seed,and the storage time should be less than 270 d. | Fan LIU Yongli XU Zhigang YAN Shugen WEI Shixin FENG | 2017 | Medicinal Plant2017，8，6： | 0 |
