摘要
缝网压裂技术是非常规油气藏改造的关键技术之一。泾河油田属于致密砂岩油藏,为了实现其水平井高效开发,根据缝网压裂作用机理和影响因素分析,对水平井缝网压裂适用性进行了分析,同时利用数值模拟软件对缝网压裂参数进行优化。结果表明:泾河油田满足缝网压裂改造的基本要求;现场试验效果表明,缝网压裂工艺技术实施效果要好于常规水平井压裂工艺,取得一定的增产效果,具备推广应用的前景。
Network fracturing is one of the key technologies to unlock unconventional reservoirs.Jinghe oil field is a tight sand oil reservoir.In order to accomplish high efficiency of horizontal wells and improve the EOR,according to network fracturing mechanism and its influencing factors analysis,the adaptability of the network fracturing was analyzed.In the mean time,by use of the numerical simulation software,parameters of the network fracturing were optimized.The results indicate Jinghe oil field matches the basic requests to do network fracturing.Compared with horizontal wells fractured with conventional fracturing technologies,field test indicates that the network fracturing can obtain increased production and has good prospect of popularization and application.
