摘　　要：目前国内新增探明储量中低渗油气藏比例越来越高,开发钻井数持续增加,多井低产形式严峻,为转变多井低产严峻形式,水平井作为油气开发的革命性技术,成为提高低渗油气藏单井产量的重要手段,但低渗油气藏水平井不经过压裂酸化改造均产量较低或无自然产能,难以达到工业开采价值,为经济有效开采众多低渗透储量,水平井分段压裂改造是提高水平井在低渗储层应用效果的技术关键。本文将结合实例,对陆地、海上低渗水平井分段压裂从压裂方式优选、压裂方案优化方面进行分析。The current domestic new proportion of proven reserves in low permeability reservoirs is higher and higher,development continues to increase the number of drilling,multiwell form of low yield,severe to shift more wells low yield,severe horizontal well as revolutionary technology of oil and gas development,become the important means to improve the low permeability reservoirs of single well production.But not after fracturing horizontal wells in low permeability reservoirs acidification transformation are yield is low or no natural capacity,it is difficult to achieve industrial production value.For economic and effective exploitation of low permeability reserves,horizontal well staged fracturing transformation is to improve the application effect of horizontal wells in low permeability reservoir of key technology.In this paper,combined with practical examples,the optimization of fracturing mode and fracturing plan for horizontal wells with low permeability on land and offshore are analyzed.
