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。
Aiming at the current production model of fractured horizontal wells in heterogeneous reservoirs, the influence of matrix permeability and initial pressure gradient heterogeneity on yield is not considered. The equivalent diameter caliper model and equivalent seepage flow resistance method are used to establish the heterogeneous oil The model predicts the steady-state production of fractured horizontal wells. The model takes into account the permeability of the reservoir matrix and the pressure gradient heterogeneity and the mutual interference between fractures. The model was used to analyze the effect of different fracture distribution, number of joints and spacing on fractured horizontal well production.
