根据三次加密后油层改造的实际需要，建立了五点和反九点井冈条件下三维两相带有水平裂缝的油藏数值模拟模型，研究了水平裂缝半径和导流能力对油井产量、无水期采收率和最终采收率等指标的影响，优化了水平裂缝参数。研究结果表明，合理的裂缝半径应为井距的２０％，导流能力为２０μm·ｃm。该结果为油井经三次加密后的水力压裂设计提供了理论依据。
According to the actual needs of oil layer reconstruction after three times of encryption, a reservoir numerical simulation model of three-dimensional two-phase horizontal fractures with five-point and nine-point Jinggang conditions was established. The effects of horizontal fracture radius and diversion capacity on well productivity, Period recovery rate and the final recovery rate and other indicators, optimizing the horizontal crack parameters. The results show that the reasonable fracture radius should be 20% of the well spacing and the flow conductivity is 20μm · cm. The result provides a theoretical basis for hydraulic fracturing design after three times of encryption.
