长岭断陷龙凤山次凹构造特征与成藏条件分析

Tectonic Characteristics and Hydrocarbon Accumulation Conditions of Longfengshan Subsag in Changling Fault Depression

龙凤山次凹的勘探成功表明该区带油气资源丰富,勘探潜力巨大,在原有的二维资料基础上部署北201井已经获得了高产工业油气流,依托三维地震资料解释成果结合最新勘探进展,以该区域构造应力分析及断裂形成机制作为切入点,系统地分析了龙凤山次凹整体构造演化特征和断裂发育特征,探讨了成藏地质条件,从而为在龙凤山次凹寻找有利油气富集区带提供可靠依据并为下一步勘探部署及研究工作提供了指导性建议。

The successful exploration of Longfengshan subsag indicates that this zone is rich in oil and gas resources, with enormous exploration potential. Well Bei201, designed according to the original two-dimensional data, yielded industrial oil and gas flow. Based on the interpretation of 3 D seismic data, together with the latest exploration progress, the author, taking the tectonic stress analysis and fault formation mechanism as a starting point, systematically analyzed the overall structural evolution and fault development characteristics in the study area and discussed the geological conditions of the hydrocarbon accumulation. The study provides a reliable basis for searching advantageous oil and gas-rich zones in the study area and guidance for further exploration and research.
