Abstract: 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.
