摘    要:深县凹陷位于冀中坳陷中部,其构造复杂,沉积类型多样,而多年来人们对凹陷内的油气圈闭(尤其是岩性地层圈闭)类型与分布规律缺乏统一认识,不利于在这类复杂断陷盆地内开展精细油气勘探。深县凹陷可划分为5个构造区带,各构造区带具有不同的沉积格局,这是各区带内油气圈闭类型存在差异的关键因素。总结出该凹陷主要发育构造圈闭、岩性圈闭、地层圈闭及潜山圈闭等4大类8亚类圈闭类型,这些圈闭类型与本区的构造沉积格局存在响应关系。其中,构造圈闭发育范围较广,主要集中在二级构造凸起带上,以深南背斜和榆科背斜为主,断块和断鼻圈闭构成了主要的圈闭类型;潜山圈闭主要发育在北部缓坡带中的深泽—刘村低凸起与何庄—深西潜山带;而岩性圈闭与地层圈闭主要发育在两个潜山带的侧翼以及南部的白宋庄洼槽带和深南背斜的两翼,这与砂砾岩透镜体、上倾尖灭砂体的分布及构造背景有关。

关 键 词:深县凹陷  圈闭类型  岩性地层圈闭  构造沉积格局

Abstract:Shenxian depression is located in the center part of Jizhong Sub-basin,North China,with extremely complicated structures and diverse sedimentation systems.There are many different recognizations of the classification of hydrocarbon traps(particularly stratigraphic trap) and their distribution in the past years,which has restriced the accurate hydrocarbon exploration in such kind of complicated faulted depressions.Five structure zones can be defined in Shenxian depression and each has its particular sediment...
Keywords:Shenxian depression  petroleum trap type  lithologic-stratigraphic trap  structural-sedimentary pattern
