摘　　要：东溪气田1955年开始勘探开发,1985年进入低压低产开采末期。通过对该气田近50年的勘探开发地质资料分析,基本上搞清了气田地质特征。采用产量统计法,计算气田顶部四个主力气藏动态储量,累积增加3.39×108m3,经复核各气藏目前有剩余储量10.42×108m3,为气田末期整体挖潜提供了依据。在此基础上,提出了气田整体增压开采和南部低渗气藏二次勘探开发方案,经济效益显著。Having had an exploration and development in 1955,Dongxi gas field has entered a late production period with low-pressure and low-production since 1985.The geologic characteristic has been clarified based on the analysis of geologic data in E & P for over fifty years.For four main gas reservoirs at the top of Dongxi gas field,the dynamic reserves have increased by 3.39×10~8m^3 by means of production statistics method.So far,the remaining reserves are 10.42×10~8m^3 after recalculation for individual reservoir,which provide a basis for overall potential of gas field in late stage.Some plans on both the supercharged production in whole gas field and the reexploration and redevelopment in southern low-permeability gas reservoirs have been presented, which brings remarkable economic benefit.
