Research on Daqing Changyuan Peripheral Oilfield Fracturing Network Candidate Selection Standard

摘要

In hydraulic fracturing process,if fracture extension net pressure is greater than the difference of two horizontal stresses at both ends of the fracture and greater than the sum of the tensile strength at both side of rock soil,a main fracture will be converted into multiple split fractures which are considered as fracture network,a system formed by such interleaving.Technology which is used to
