辽河盆地齐3-17-5块微幅度构造成因研究及其对区块开发的意义

油田地质综合研究的结构研究是一个重要组成部分的内容,3-17-5块之前的结构图等高线间距比较粗糙很难准确地反映较小的变化。它不是一种微观的结构图。将等高线间隔定为5m才能为进一步精细解释油藏,并对其结构进行分析和研究。利用钻井及动态资料,结合三维地震资料,对齐3-17-5块进行了微幅度构造(以下简称微构造)特征的研究,依据微构造形态将其划分为正向微构造、负向微构造和斜坡微构造,其具体包括小高点、小断鼻、小槽沟、小断沟等,从而分析出微构造形成原因,及其对区块进一步开发的深远意义。

The Formation of Mini-structure Analysis in the Qi 3-17-5 Region of Liaohe Basin and Its Importance to the Block Development

In the geological comprehensive study,structure research was an indispensable part of content.The contour map of the Qi 3-17-5 structure spaced 50 meters before.It was sketchy and difficult to finely reflect small changes in the structure.It was a macro structure maps.In order to further interpret oil reservoir,in this research the contour map of the structure spaced 5 meters.By using drilling and dynamic information,combined with the 3D seismic data,it could be better to interpret the structure.To research features of the mini-structure(hereinafter referred to as the ministructure) of the Qi 3-17-5 region,according to the structure form,it can be divided into positive micro structure,negative micro structure,slope micro structure,including small highs,small structure,small faults nose and so on.We could analyze the mini-structure formation and its importance to this block development.
