摘　　要：针对目前非均质油藏压裂水平井产量计算模型未考虑基质渗透率和启动压力梯度非均质性对产量的影响,应用当量井径模型和等值渗流阻力法,建立了非均质油藏压裂水平井稳态产量预测模型,模型考虑了油藏基质渗透率和启动压力梯度非均质性及裂缝间的相互干扰。利用该模型分析了不同裂缝分布、条数及间距组合对压裂水平井产量的影响。In view of the problem that the present productivity prediction model for fractured horizontal well in heterogeneous reservoirs does not consider the anisotropy of matrix permeability and start-up pressure gradient, a stable productivity prediction model for fractured horizontal well in heterogeneous reservoirs has been established by using equivalent well model and equivalent percolation resistance method, this model has considered the anisotropy of matrix permeability and start-up pressure gradient and mutual interference between the cracks. The model has been used to study the influence of different fracture distribution, the number and space of fractures on production of fracturing horizontal wells.
