水力压裂改造低渗油藏是目前主要的增产措施,其能否获得最佳的经济效益取决于对改造地层的认识程度即所建立的水力压裂模型.本文首先建立了沙南低渗油藏地质模型和三维水力压裂模型,而后,以此为基础研究了三维水力压裂模型敏感性参量以及不同水力压力模型模拟结果.最后建立了沙南油田水力压裂模型,用此模型可准确地指导实际水力压裂。
Hydraulic fracturing to transform low permeability reservoirs is the main stimulation measures at present, and whether it can obtain the best economic benefits depends on the understanding of the strata that is the established hydraulic fracturing model.In this paper, Shanan low permeability oil Reservoir geological model and three-dimensional hydraulic fracturing model, and then based on this, the three-dimensional hydraulic fracturing model sensitivity parameters and the simulation results of different hydraulic pressure models were established.Finally, the hydraulic fracturing model of Shanan Oilfield was established, which can be used to accurately Instruct the actual hydraulic fracturing.
