According to organic geochemistry and organic petrology, the hydrocarbon sources in Pingliang Formation, W. Ordos basin, are systematically evaluated. The organic abundance of hydrocarbon source in this research is higher in the upper part of profiles than in the low, and more in mudstone than in carbonate. Most of organic matters become sapropelic, and few are humic-sapropelic in the regions of Shibangou and Zhuzisan. According to stable isotopes of carbon and oxygen in carbonate rock, boron index and ratios of elements, palaeo-salinity and sedimentary velocity are calculated. The two factors of paleao-salinity and sediment velocity, which control the distribution of organic matters, are discussed. Good relationship is found between water salinity and abundance of organic matter; in contrast, poor correlation is observed between salinity and types of organic matters. The relative sediment velocity in the research regions is also related with organic abundance and types. A low sediment velocity would lead to high abundance and good type of organic matters, and vice versa.

Analysis of the effect of changes in fluid properties of rocks on the compressional-wave velocity VP and shear-wave velocity Vs is very important for understanding the rock physical properties, especially in oilfield exploration and development. The fluid substitution process was analyzed by using ultrasonic measurement and theoretical calculations. The results showed that the effect of fluid substitution on the rock elastic modulus was mainly controlled by fluid properties, saturation, and confining pressure. For a rock with specific properties and porosity, the result of theoretical prediction for fluid substitution accorded with the experimental result under high confining pressure （higher than 60 MPa for our experimental data）, but failed to describe the trend of experimental result under low confining pressure and VP predicted by Gassmann＇s equation was higher than that measured by experiment. A higher porosity resulted in stronger sensitivity of the bulk modulus of saturated rocks to the change of fluid properties.

The Paleozoic strata in the Tarim Basin, Sichuan Basin and Ordos Basin are the major targets for marine petroleum exploration, with developed high quality hydrocarbon, mainly argillite. The deep burial of these source rocks suggests that they mainly develop gas instead of oil. But different maturities of organic matter may lead to different hydrocarbon facies. Through thermochemical sulfate reduction (TSR), the hydrocarbon in the carbonate rocks may undergo a process of pyrolytic cracking and be catalyzed into gases. The marine reservoirs mainly consist of carbonate and clastic rocks, and the former is controlled by sedimentary facies, dolomitization, solution, TSR and cracking. The multiphase tectonic cycling develops multiple source-reservoir-cap combinations and diversified types of traps and reservoirs, featuring multiphase reservoir formation, mainly late-phase formation or consolidation. Palaeo-uplifts play a controlling role in hydrocarbon accumulation. Differences in major source rocks in the three basins lead to different locations of oil-gas accumulation layers, different types and patterns of reservoirs and different features of reservoir formation.

在我国,对于注水开发油田,水驱曲线法是预测油田可采储量的重要方法。该方法的有效应用,有赖于直线段选取的可靠性和极限含水率确定的合理性。然而,对于不同流度注水开发油田,由行业标准统一规定,一律选用98%的含水率作为预测可采储量的作法,不但是不恰当的,也是缺乏理论依据的。对于业已进入中高含水期产量递减的油田,基于以往笔者的研究成果,依据不同的技术经济条件,应用确定经济极限产量的概算法,提出了确定经济极限含水率的方法,并用于水驱曲线法,预测油田的经济可采储量。通过实例的应用表明,该方法是实用有效的。

The buried-hill trend is a typical style of the petroliferous structure in the faulted basin of eastern china. The Xinglongtai structure trend in the Liaohe subbasin,Bohai Bay Basin is a buried faulted-hill trend resulting from the periodic faulting of the Tai’an-Dawa faults. The structure was cut by various faults,which are interlinked and constitute the conduits for petroleum migration. petroleum accumulated in the Tertiary sandstones and pre-Tertiary basement of metamorphosed rocks through the migration pathways of the fault system. petroleum in the structure was derived from different hydrocarbon kitchens to form a hybrid field complex. petroleum charged the structure from different directions and accumulated in various reservoirs through different pathways in different times. The accumulations in the buried hill trend of Xingongtai are composed of two types of traps in the two stratigraphic systems: traps in the Tertiary sandstones were formed by the fault blocks and by the pinchout of the sandstone,and traps in the pre-Tertiary basement of metamorphosed rocks were formed by fissures in the inner part of the buried hills and by the unconformity near the surface of the buried hills.

对库车坳陷的成藏期次和成藏过程进行了研究 ,结果表明 ,库车坳陷具有两期成藏的地质条件。晚白垩世—早第三纪末在山前已经形成挤压背景下的构造圈闭 ,该时期的圈闭主要聚集源自三叠系烃源岩的油气 ;中新世以来是库车前陆盆地发育的时期 ,此时构造变形作用最强烈 ,形成的圈闭以聚集晚期生成的天然气为主。油气源对比结果和储层沥青、包裹体的研究为库车坳陷两期成藏提供了直接的地球化学证据 ,库车坳陷经历了早期油气的聚集、破坏和晚期天然气聚集、调整的过程。早期 (白垩纪末期—早第三纪 )成藏以侧向运移为主 ;晚期 (晚第三纪以来 ,主要是上新世—第四纪 )成藏则具有侧向、垂向运移并重的特点。
