滚动背斜形成机理探讨

Inquiry into the formation mechanism of rollover anticlines

第二期，在区域性压应力作用下形成滚动背斜。

Thc second was the formation of the rollover anticlines under the regional compressive stress .

经研究可知，陆上及滨岸带与生长断层下降盘伴生的滚动背斜是主要油气聚集部位。

The rolling anticline associated with declining plate of growth fault is a main oil and gas accumulating position .

3）由一条或多条反向（北倾）断层与主控断层形成的滚动背斜构造；

3 ) rollover anti - clines that have been formed by the joint action of one or more antithetic ( north-dipping ) faults and the master fault ;
