松辽盆地南部大冷断陷基本油气地质条件分析
Oil and Gas Geological Conditions of Daleng Fault Depression, Southern Songliao Basin
【摘要】 松辽盆地南部大冷断陷是中国石化在松南诸小断陷群部署的重点勘探区域之一。大冷断陷与已获重大突破的彰武断陷在构造位置上相邻,钻遇地层相同,烃源岩地化指标相似,并且已钻遇良好油气显示。主要利用二维地震测线的构造解释综合储层反演方法,结合钻井资料的研究成果,寻找出大冷断陷下步勘探的有利方向。通过和彰武断陷的类比分析,说明大冷断陷可能存在与其相似的成藏条件并具有一定勘探潜力,提出了下步勘探的有利目标。
【Abstract】 In 2011, a major breakthrough was made for Zhangwu fault depression, southern Songliao Basin. This breakthrough began with an exploration and development of many small fault depressions in southern Songliao Basin. Since then, some seismic lines and optimized some favorable depressions have been deployed to be the important regions by Sinopec for future exploration. Daleng fault depression is one of them. And structurally, it is adjacent to Zhangwu fault depression. And for these two fault depressions, the drilled strata are the same and the geochemical indexes of source rock are similar, and the drilled oil and gas show is better. In this study, the favorable direction for future exploration in Daleng fault depression is found out based on structural interpretation of 2D seismic line and reservoir reverse method. Moreover, there is a certain exploration potential.
