Oil and Gas Geological Conditions of Daleng Fault Depression, Southern Songliao Basin
【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.
