摘　　要：寻找高效优质储量,实施低成本高效益勘探开发,是低油价背景下的战略抉择.本文立足于项目自主研究、油气勘探生产跟踪和国内外发展态势分析,以突出高效优质资源形成与分布规律为研究重点,结合油气勘探实践,针对中国陆上断陷、坳陷、前陆和克拉通4大类原型盆地,包括松辽、渤海湾、鄂尔多斯、准噶尔、塔里木、柴达木等7大主要盆地,以及酒泉、江汉、南方等5个中小盆地中的68个远源/次生油气藏,开展了油气藏地质特点、成藏条件、资源潜力、分布规律和勘探前景分析.明确了远源/次生油气藏埋藏浅、物性好、产能高、建产快、动用程度高,属典型高效优质资源,是近期低成本高效益勘探开发的重要领域.剖析了我国远源/次生油气藏形成的4个有利地质条件,指出我国次生油气藏分布范围广,资源规模大,勘探前景好.明确了我国准噶尔盆地中浅层、鄂尔多斯盆地侏罗系、塔里木盆地塔中和塔东、渤海湾盆地新近系、松辽盆地黑帝庙油层等是中国陆上大型远源/次生油气藏规模有利聚集区,其中凸起区、斜坡带和晚期复杂断裂带是远源/次生油气藏富集带,油气藏类型主要是岩性、地层油气藏和低幅度构造油气藏.本文为加强我国远源/次生型高效优质资源研究,实现低成本高效益勘探开发提供借鉴和参考.It is a strategic choice to find the efficient and high quality oil-gas reserves and reduce the exploration cost under the background of low oil prices. Based on independent research, tracing analysis of oil-gas exploration and production, development trend of global oil-gas exploration practice, we analyzed the geological characteristics, reservoir forming conditions, resource potential, distribution law and exploration prospect of oil and gas reservoirs. In the course of study, we mainly focused on the formation and distribution of high quality resources of fault basin, depression basin, foreland basin and craton basin including Songliao basin, Bo-hai Bay basin, Ordos basin, Junggar basin, Tarim basin, Qaidam basin. Meanwhile, we also studied five middle and Small basins including Jiuquan basin, Jianghan basin, South basin and 68 far-source secondary oil and gas reservoirs. We have made clear that secondary oil and gas reservoirs are shallow buried, with good physical properties, high productivity, rapid construction capacity and high producing degree, and they are an important area of low cost and high benefit exploration and development in the near future. Four favorable geological conditions for far-source secondary oil and gas reservoirs were analyzed and results show that the secondary reservoirs have the characteristics of wide distribution, large scale and good prospects for ex- ploration. It is confirmed that shallow layers in Junggar basin, Jurassic formations in Ordos basin, middle and east of Tarim basin, Neogene formations in Bohai Bay basin and Heidimiao oil layer of Songliao basin are favorable accumulation areas of large far-source secondary oil and gas reservoirs. The uplift area, the slope belt and the late complex fault zone are the enriched zones of far-source secondary oil and gas reservoirs. The types of oil and gas reservoirs are mainly lithologic stratigraphic reservoirs and low amplitude structural reservoirs. The results of this paper can provide reference for the research on far-source
