摘要
济阳坳陷石炭-二叠系的勘探目标主要是煤成气藏,通过勘探,已在惠民、孤北等地区取得一定进展,证实了济阳探区煤成油气的勘探潜力。但整体勘探程度和认识程度比较低,近年来,取得了大量的实钻井资料及高精度三维地震资料。本文在构造演化分析的基础上通过分析济阳坳陷石炭-二叠系煤成气藏的烃源岩条件和保存条件,为济阳坳陷煤成气藏勘探指出了有利方向。
The exploration target of Carboniferous Permian in Jiyang Depression is mainly coal formed gas reservoir.Through exploration,certain progress has been made in Huimin,Gubei and other areas,which confirms the exploration potential of coal formed oil and gas in Jiyang exploration area.However,the overall exploration level and understanding level are relatively low.In recent years,a large number of real drilling data and high-precision 3D seismic data have been obtained.Based on the analysis of tectonic evolution,this paper points out the favorable direction for the exploration of coal formed gas reservoirs in Jiyang Depression by analyzing the source rock conditions and preservation conditions of the Carboniferous Permian coal formed gas reservoirs in Jiyang Depression.
