摘要

利用三维高精度地震资料,通过对松辽盆地十屋断陷典型剖面进行精细解释和研究,剖析了四个反转构造带各具特色的反转构造特征及样式。孤家子后五家户反转构造带以“欺压式断层”为特色,小五家子四家子反转构造带中、浅层表现为箱形背斜,深层发育有“欺压式逆断层”,秦家屯反转构造带为发育在早期半地堑之上的“尖棱状”背斜,皮家毛北张家屯反转构造带表现为小型背斜或向斜。这些反转构造发育在深层生烃凹陷附近,生、运、聚、储的配置关系极佳,是重要的油气圈闭。
Four reverse structural zones in Shiwu rift depression were determined and their structural styles were described on the basis of interpreting typical profiles by using 3-D high resolution seismic data. The Gujiazi-Houwujiahu reverse structural zone is characterized by tyrannous faults, whereas the Xiaowujiazi-Sijiazi reverse structural zone shows a box-like anticline in shallow place and tyrannous reverse faults in depth. The Qinjiatun reverse structural zone is a tine ridge anticline developed above the early half-graben. The Pijia-Maobe-Zhangjiatun reverse structural zone assumes a small anticline or syncline. As important hydrocarbon traps, these reverse structural zones are usually distributed near the deep source depression and have favorable petroleum geological conditions.
