简单斜坡是具有构造平缓和低断裂密度特征的弱构造带,断层位移褶皱作为简单斜坡内一种常见的断层相关褶皱类型,能够形成重要的油气圈闭构造.为了准确识别断层位移褶皱及其相关油气圈闭,以三维地震为基础,结合不同生长阶段断层位移变化来阐明不同类型断层位移褶皱形成机制,应用断层分段性和断层平面分段生长阶段定量表征方法来识别断层位移褶皱的类型及发育部位.同时,以文安斜坡中南部为研究靶区,探讨位于文安油田内史各庄和议论堡地区主要含油区附近断层形成的断层位移褶皱类型,阐明其相关圈闭构造与油气分布关系.研究结果表明,王仙庄断层和SGZ1断层都处于“硬连接”生长阶段,能够形成“硬连接”断层位移褶皱,SGZ2和SGZ3断层处于相互作用的“软连接”阶段,形成“软连接”断层位移褶皱.断层位移褶皱相关圈闭发育部位与文安油田油气分布关系表明断层位移褶皱相关圈闭构造是文安油田主要的含油气圈闭类型,富集了文安油田大部分的油气储量.
Simple slopes are weak tectonic belts with features of gentle tectonics and low fault density, and fault dislocation fold, as a common type of fault-related fold within a simple slope, can form important oil-gas trap structures.In order to accurately identify the fault displacement fold and its correlation Based on the 3D seismic data and combining the displacement changes of faults in different growth stages, the oil and gas traps are used to clarify the formation mechanism of different types of fault fold folds. The classification of fault displacement folds and the quantitative characterization of the fault plane- Meanwhile, taking the middle and southern parts of the Wen’an slope as the research target, the paper discusses the types of fault displacement folds formed in the faults near the main oil-bearing areas in the Shigezhuang and Haibaopu areas of Wen’an Oilfield, and elucidates the relationship between the related trap structures and hydrocarbon distribution. The results show that both the Wangxianzhuang fault and the SGZ1 fault are in the stage of “hard connection” and can form “hard connection” fault displacement folds, and the SGZ2 and SGZ3 faults are in an interacting “soft connection” stage, forming a “ Soft connection ”fault displacement folds. Fault-related fold-related traps and Wen’an oilfield oil and gas distribution Department show that fault displacement fold associated trap structure is the text Oilfield as the main hydrocarbon trap types, most of the enriched text Oilfield as oil and gas reserves.
