【摘要】：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.
[Abstract]:Simple slope is a weak structural zone with the characteristics of gentle structure and low fracture density. Fault displacement fold is a common type of fault-related fold in simple slope. In order to accurately identify the fault displacement fold and its related oil and gas traps, it is based on 3D earthquakes. The formation mechanism of different types of fault displacement folds is explained by combining the variation of fault displacement in different growth stages. The types and development sites of fault displacement folds are identified by means of quantitative characterization of fault segmenting and fault plane growth stages. At the same time, the central and southern part of Wenan Slope is taken as the research target. This paper discusses the types of fault displacement folds formed by faults near the main oil-bearing areas in Gezhuang and Yiliubu areas of Wenan Oilfield, and clarifies the relationship between the relevant trap structures and the distribution of oil and gas. Both the Wangxianzhuang fault and the SGZ1 fault are in the "hard connection" growth stage, which can form the "hard connection" fault displacement fold, SGZ2 and SGZ3 faults are in the "soft connection" stage of interaction. The formation of "soft connection" fault displacement fold. The relationship between the development of fault displacement fold associated trap and the distribution of oil and gas in Wenan Oilfield indicates that the fault displacement fold related trap structure is the main type of oil-bearing trap in Wenan Oilfield. It has enriched most of the oil and gas reserves in Wenan Oilfield.
