摘要

义南地区天然气资源十分丰富。通过对天然气气源、沉积相、储盖层特征、圈闭类型等成藏条件的分析,结合气藏地震反射特征及三维气藏描述,系统总结了义南地区中浅层气藏的成藏条件及分布规律,评价了义南地区的资源潜力,指出义南断裂带、北部凸起带及斜坡带为有利的含气区带,并取得了较好的钻探结果。

The resource of natural gas in Yinan region is

sufficiently abundant . After analyzing and studying the gas

source , sedimentary facies , reservoir and overlying formation

in medium and shallow zone in Yinan region , this paper

summarizes the forming conditions and the regularity of gas

reservoirs’distribution. On the base of analyzing the seismic

reflected character and describing the gas - bearing sand body ,

this paper predicts the resource in Yinan region and indicates

that the fracture belt , north arch belt and slope belt are

favorable gas - bearing region. The effect of drilling is

preferable.
