摘要
辽东湾地区地质构造形成于晚渐新世,是受走向滑动断层控制的扭动构造带。其构造类型有雁列构造、反转构造、入字形构造和帚状构造。构造的形成与成油期相匹配。油(气)在地应力的作用下,从高压的生油凹陷中心向低压的凹陷边缘运移、聚集在凹陷边缘的圈闭内。雁行排列构造带是辽东湾地区寻找油(气)
Wrench structures of Liaodong Bay by and large were for-med during late Oligocene in response to strike-slipping faulting.Structural styles fall into categories of en echelon,inverted,etc.More important is the excellent timing of structure forma-tion and principal hydrocarbon generation and expulsion.Hydr-ocarbons generated in geopressured thermal kitchens had the te-ndency of migrating towards the marginal areas of them wherepressure was lower.Therefore the wrench structures there,forexample en eohelon structures,are the very locus for oil huntingin the region.
