海拉尔盆地贝尔凹陷反转构造研究
|
摘要
贝尔凹陷是海拉尔盆地中一个早期伸展、晚期反转的早白垩世伸展凹陷。通过综合应用地震、钻井等资料,对贝尔凹陷的形成演化进行了深入分析,认为贝尔凹陷早白垩世末期发育的反转构造丰富了伸展构造样式,提供了有利于油气聚集的构造圈闭;决定贝尔凹陷反转构造含油性的主要因素是油气生成时间、运移时间与反转时期的配置和反转强度对油气聚集的控制作用。
Beier sag is an extensional sag in Early Cretaceous that is early extension and later inversion in Hailaer Basin. Thorough analysis on the formation and evolution of Beier sag is conducted based on the application of seismic and drilling data. It is revealed thatinversion structures that developed in the end of Early Cretaceous enriches the extensional structures style and provides structural trapfavorable for oil and gas accumulation. The key factors that determine the petroliferous properties of inversion structures of Beier sag arethe configuration of time for oil and gas generation, migration and inversion and the controlling function of inversion intensity to oil andgas accumulation.
