摘要
以新疆油田外围某低渗透油藏为研究对象,根据实际油藏的地质特征建立数值模型,利用数值模拟方法对水平井压裂开发方式进行研究。研究表明,水平井压裂开发方式可有效提高油田采收率,获得较好的经济效益。采用正交试验设计方法,以采出程度和内部收益率为评价指标,得到影响开发效果的主要压裂参数依次为裂缝条数、裂缝半长、裂缝导流能力、裂缝间距和裂缝角度;确定了该油藏最优水平井压裂参数组合方案:裂缝条数为3条,裂缝半长为100 m,裂缝导流能力35,200 m的裂缝间距,裂缝角度90°,为现场水平井压裂开发方案制定提供理论指导和技术支持。
Abstract：According to the geological characteristics of the reservoir, horizontal well fractur- ing development mode has been studied for a special peripheral low permeability reservoir of Xinjiang oilfield by using numerical simulation methods. Research shows that horizontal well fracturing can enhanced oil recovery effectively and obtain good economic effect. On the ba- sis of orthogonal experimental design, the importance order of the influence of fracture pa- rameters on recovery percent and internal rate of return is as follows, the number of frac- tures, fracture half-length, fracture conductivity, fracture spacing and fracture angle, mean- while the best combination of fracture parameters has been optimized, 3 fractures, fracture half-length of 100 m, fracture conductivity of 35, fracture spacing of 200 m, fracture angle of 90°, thus providing theoretical instruction and technical support for mine program develop-ment.
