摘　　要：为研究海洋低渗透油田压裂水平井参数,针对BZ25-1油田目前地质、开发特征,应用Eclipse软件建立压裂水平井机理模型,对低渗透压裂水平井参数进行优化。结果表明:BZ25-1油田水平井的水平段最优长度为400 m;水平段最优位置为储层中部;最优压裂裂缝条数为4;最优裂缝半长为90 m。研究结果为类似油田压裂水平井参数优选问题提供了思路和借鉴。In order to wsearch the parameters of fractured horizontal well in marine low permeability oilfields, based on the current geology and development characteristics of BZ25-10ilfield, this paper takes advantage of Eclipse software to establish the mechanism model of fractured horizontal well. The para,neters of fraetured horizontal well in marine low permeability oilfield are optimized. Resuhs show that the optimum length of horizontal well in BZ25-1 Oilfield is 400 m; the optimal position of horizontal section is in the middle part of reservoir the optimal numbers of fraetures are 4; the optimal fracture half-length is 90 m. Researches in this paper provide new ideal and reference for parameter optimization of fractured horizontal well in BZ25-10ilfield.
