摘　　要：新沟嘴组油藏是江汉盆地第二大含油层系,资源量丰富。但其低孔低渗的油藏特征,导致开发手段有限,开发效果偏差。利用油藏工程与数学统计分析结合的方法,对开发中存在的潜力点进行分析,挖潜老油田剩余油分布特征。同时,利用全支撑压裂工艺技术,形成了一种适合低渗透薄互层油藏在高含水开发阶段有效提高采收率的方法。Xingouzui Formation reservoir is the second largest oil-bearing stratum in Jianghan basin,with abundant resources.However,the reservoir characteristics of low porosity and low permeability lead to limited treatments and poor development effect.Combined with the reservoir engineering with mathematical statistic analysis,the development potentials are analyzed to tap the remaining oil distribution characteristics of old oilfields.At the same time,a method is developed by utilizing the all-propping fracturing technology to improve the recovery efficiency of low-permeability thin interbedded reservoirs in the stage of high water-cut development.
