弧形断裂是渤海湾盆地重要的油气富集带。本文利用肃宁地区三维地震资料、钻井、测井资料分析了该区新生代断裂活动性,并在此基础上探讨了弧形断裂活动对油气成藏的控制作用。研究认为,肃宁地区弧形断裂活动具有明显的阶段性,断裂活动对油气聚集规律具有重要的控制作用,主要表现在:断裂活动控制整个油气成藏过程,形成了形式多样的油气藏类型。
Arc fracture is an important hydrocarbon accumulation zone in the Bohai Bay basin. Based on the 3D seismic data, drilling and well logging data in Suning area, this paper analyzes the Cenozoic fault activity in this area, and on this basis, discusses the controlling role of arc fault activity on hydrocarbon accumulation. The study shows that the arc-shaped fault activity in Sunning area has obvious stage, and the fault activity plays an important role in controlling the hydrocarbon accumulation. The main activities are as follows: the fault activity controls the whole process of hydrocarbon accumulation and forms various types of oil and gas reservoirs.
