Research Progress in the Petroleum and Natural Gas Geological Theory of China

Acta Geologica Sinica(English Edition) 2016年第4期90卷 1236-1248页

作者： MA Yongsheng zhao peirong China Petroleum & Chemical Corporation Beijing 100728 China

The Chinese landmass, as a composite region, consists of multiple small continental blocks, such as Sino-Korea, Yangtze, Tarim, etc., and orogenic belts. Because of its distinctive tectono-sedimentary evolution, China＇s oil/gas-bearing regions differ remarkably from that elsewhere in the world. For instance, in comparison to the Middle East oil/gas-bearing regions which are characterized by Mesozoic-Cenozoic marine oil/gas-bearing beds, early oil and gas discoveries in China are distributed mainly in Mesozoic-Cenozoic continental sedimentary basins. Generation of oil from terrestrial organic matter, or terrestrial oil generation, and the formation of large oil/gas fields in continental sedimentary basins were previously the major characteristics of petroleum geology of China. However, in the past 20 years, a series of major oil and gas discoveries from marine strata have been made. Marine oil/gas fields in China are mainly distributed in the Tarim, Sichuan, and Ordos basins, which are tectonically stable and covered with Mesozoic-Cenozoic deposits. In these basins, hydrocarbon-bearing strata are of old age and the oil/gas fields are commonly deeply-buried. Cumulatively, 995 oil/gas fields have been found so far, making China the fourth largest oil-producing country and the sixth largest gas-producing country in the world. In terms of petroleum and natural gas geology, theories of hydrocarbon generation from continental strata, such as terrestrial oil generation and coal-generated hydrocarbons, etc., have been established. Significant progress has been made in research on the sequence stratigraphy of continental strata, formation mechanisms of ultra-deep clastic reservoirs, and hydrocarbon accumulation in the continental subtle reservoir. Regarding research on the marine petroleum geology of China, with respect to the major characteristics, such as deeply-buried reservoirs, old strata, and multiple phases of transformation, important advances have been made, in areas

Taking advantage of the successful experience in exploring and discovering the Puguang Gasfield,and targeting the Changxing Formation-Feixianguan Formation organic reef and shoal lithological trap,SINOPEC drilled Well Yuanba 1 in the Bazhong area in Northeast Sichuan in 2006,and discovered the Yuanba Gasfield with a high-production commercial gas flow of 503×10^(3) m^(3)/*** a normal-pressured lithological gas reservoir with high H_(2)S content,Yuanba Gasfield is characterized by weak tectonic deformation and deep burial,with an average depth of 6,600 m in the central part of the gas reservoir,and is the deepest marine gas field in the Sichuan *** Gasfield is dominated by large-scale reef-shoal reservoirs of Changxing *** formation of the reservoirs was primarily controlled by early meteoric freshwater dissolution and dolomitization,and less affected by deep-burial dissolution and tectonic movement.A comparative analysis was made on the characteristics of deep reef-shoal reservoirs in the Yuanba and Puguang gas fields so as to explore their formation *** is concluded that the reservoir size and early pore development was controlled by early depositional-diagenetic *** formation and dissolution were controlled by structure-fluid coupling,pore reworking and preservation is determined by fluid-rock interaction.

Practice and theoretical and technical progress in exploration and development of Shunbei ultra-deep carbonate oil and gas field,Tarim Basin,NW China

引用

Petroleum Exploration and Development 2022年第1期49卷 1-20页

作者： MA Yongsheng CAI Xunyu YUN Lu LI Zongjie LI Huili DENG Shang zhao peirong China Petroleum and Chemical Corporation(Sinopec) Beijing 100728China Northwest Oilfield Company SinopecUrumqi 830011China Petroleum Exploration and Production Research Institute SinopecBeijing 102206China

In this review on the exploration and development process of the Shunbei ultra-deep carbonate oil and gas field in the Tarim Basin, the progress of exploration and development technologies during the National 13th Five-Year Plan of China has been summarized systematically, giving important guidance for the exploration and development of ultra-deep marine carbonate reservoirs in China and abroad. Through analyzing the primary geological factors of “hydrocarbon generation-reservoir formation-hydrocarbon accumulation” of ancient and superposed basin comprehensively and dynamically, we point out that because the Lower Cambrian Yuertusi Formation high-quality source rocks have been located in a low-temperature environment for a long time, they were capable of generating hydrocarbon continuously in late stage, providing ideal geological conditions for massive liquid hydrocarbon accumulation in ultra-deep layers. In addition, strike-slip faults developed in tectonically stable areas have strong control on reservoir formation and hydrocarbon accumulation in this region. With these understandings, the exploration focus shifted from the two paleo-uplifts located in the north and the south to the Shuntuoguole lower uplift located in between and achieved major hydrocarbon discoveries. Through continuing improvement of seismic exploration technologies for ultra-deep carbonates in desert, integrated technologies including seismic acquisition in ultra-deep carbonates,seismic imaging of strike-slip faults and the associated cavity-fracture systems, detailed structural interpretation of strike-slip faults, characterization and quantitative description of fault-controlled cavities and fractures, description of fault-controlled traps and target optimization have been established. Geology-engineering integration including well trajectory optimization,high efficiency drilling, completion and reservoir reformation technologies has provided important support for exploration and developmen

Insulin-Enhanced Antitumor Effect of 5-Fluorouracil in vivo

引用

Chinese Journal of Clinical Oncology 2008年第4期5卷 277-280页

作者： Rui Wang Qingxia Fan Xiangjie Hu Liuxing Wang peirong zhao Ruilin Wang The First Hospital of Zhengzhou University Zhengzhou 450052 Henan Province China. Cancer research Center Zhengzhou University Zhengzhou 450052 Henan Province China. Department of Pharmacy Medical College Zhengzhou University Zhengzhou 450052 Henan Province. China.

OBJECTIVE To determine if insulin treatment can enhance the antitumor effect of 5-fluorouracil （5-FU）, and to explore the mechanism of the enhancemdnt of insulin. METHODS S180 sarcoma, H22 liver cancer and human Eca-109 esophageal cancer cells were transplanted into nude mice to evaluate the inhibitory effect on tumor growth of insulin alone or in combination with 5-FU. The levels of serum insulin-like growth factor-I （IGF-I） and insulin-like growth factor binding protein-3 （IGFBP-3） were determined. RESULTS Compared with 5-FU treatment alone, the tumor weight of H22 liver cancer and S180 sarcoma was reduced further with high, medium and low-dose insulin （0.09, 0.06, 0.03 U/20 g）＋ 5-FU treatment. When a high dosage of insulin ＋ 5-FU was administered, tumor weight was significantly reduced （P 〈 0.05）. The inhibitory rate of growth of S180 sarcoma and H22 liver cancer reached 50.2% and 51.4%, respectively, which was significantly higher than 24.9% and 27.9% in the group receiving 5-FU alone （P 〈 0.05）. High, medium and low-dose insulin combined with 5-FU significantly inhibited the growth of Eca-109 cancer cells （P 〈 0.05）. Compared with the control group, the level of serum IGF-1 decreased （P 〈 0.05）, whereas the level of serum IGFBP-3 slightly increased in the 5-FU ± insulin groups （P 〉 0.05）. In mice with H22 liver cancer and S180 sarcoma the IGF-1 level with highdose insulin ＋ 5-FU treatment was significantly lower compared to treatment with 5-FU alone （P 〈 0.05）, but the difference was not significant in mice transplanted with esophageal cancer cells. CONCLUSION Insulin can enhance the anti-tumor effect of 5-FU without significantly increasing 5-FU toxicity. Although changes in the serum IGF-1 or IGFBP-3 level do not explain the mechanism of the insulin-induced enhancement on 5-FU on growth, a decrease in the level of serum IGF-1 and an increase in serum IGFBP-3 may be important in the chemotherapeutic response.

通过多年的勘探开发实践,我国在四川盆地及其周缘上奥陶统五峰组—下志留统龙马溪组实现了页岩气商业开发,认识到页岩气藏具有自生自储、低孔特低渗特征,属于“人工气藏”,其高产是由地质和工程两类因素共同控制。地质因素决定页岩气是否富集,工程因素则是决定页岩气是否高产的重要条件。准确识别“甜点层”,优选确定水平井穿行层位,是页岩气能否获得高产的关键。对涪陵页岩气田焦石坝区块水平井穿行层位优选实例的剖析表明,精细研究是准确优选水平井穿行层位的基础,地质、工程一体化紧密结合是准确优选水平井穿行层位的关键。根据各个地区具体地质条件,将地质、工程结合,优选水平井穿行层位,是页岩气勘探开发最终获得成功的重要保障。
