| 摘 要： | 油气输导系统和油气运移的特征决定油气藏形成与分布 .根据惠民凹陷临南地区的实际地质条件的分析 ,指出在异常低压的背景下 ,该研究区输导系统和油气运移聚集呈现如下特征 :( 1 )该区输导系统主要由砂体和断层组成 ,断层 (以夏口断层为主 )在油气运移中起着更重要的作用 ,且受断层面形态控制 ,两个北凸面起着汇聚油流的作用 ;( 2 )由于异常低压使得运移动力非常弱 ,油气运移表现为低速流近距离运移的特征 ,油气藏主要分布在夏口断层两侧 ,斜坡南侧高部位无油气藏

| Abstract: | The characteristics of carrying bed system and hydrocarbon migration determine the formation and the distribution of reservoirs. Based on the analysis of geologic conditions in Linnan district, Huimin Sag, the conclusions are drawn out: (1) the carrying bed system in this area is mainly composed of sand bodies and faults. The faults, especially Xiakou fault, play a more important role in hydrocarbon migration, and the migration is controlled by the shape of the fault surfaces, two north convex faults have effect of concentrating oil flows; (2) the poor power, produced by the abnormally low pressure, causes short distance migration of the oil flows at low speed, and the reservoirs in this area distribute along Xiakou fault. |
