辽河盆地大民屯凹陷法哈牛构造太古界古潜山成藏特征研究

对辽河盆地大民屯凹陷法哈牛构造太古界古山构造特征进行研究认为：该区古潜山可分为高、中、低3个台阶.同时,对其储层特征、油气藏类型及油气成藏控制因素进行了分析,总结出该区的油气成藏模式.该区紧临荣胜堡生油洼陷,具备较好的油源条件;太古界花岗岩储层具有较好的储集条件;在构造运动控制下形成的高、中、低潜山是油气聚集的良好场所.在油气成藏模式的指导下,对该区中、低潜山进行滚动勘探部署,取得了较好的效果,使该区古潜山的勘探取得了新的突破.

Study of Archaeozoic buried hill reservoir accumulation in Fahaniu structure of Damintun depression, Liaohe Basin

Study of the structure characteristics of Archaeozoic buried hill in Fahaniu,Damintun depression,Liaohe Basin indicates that the buried hills in this area can be divided into 3 steps of high,middle and low.Reservoir characteristics,types and controlling factors are also analyzed.Oil and gas accumulation mode in this area is summarized.This region is near Rongshengpu oil-depression which was a good oil source.Archaeozoic granite reservoir has good reservoir conditions.The high,middle and low buried hills formed by tectonic movement were good places for oil and gas accumulation.Progressive exploration is deployed in the middle and low buried hills in this area and has achieved exploration breakthrough.
