DOI: https:// doi.org/10.15446/esrj.v24n4.91473 The zonal productivity prediction model of volume fractured horizontal wells in tight reservoirs is established in this study based on the physical model of volume fractured horizontal wells to study the near-well seepage law of volume fractured horizontal wells in unconventional tight reservoirs. The conformal transformation and iteration method are used to solve the problem. Compared with Fan Zifei's and Ning Zhengfu's method, the optimization of fractured horizontal wells' production parameters is studied.

非常规致密油储层特征、改造技术及产能预测。地球科学研究，24(4)，507-512。本文在体积压裂水平井物理模型的基础上，建立了致密储层体积压裂水平井层间产能预测模型，研究非常规致密储层体积压裂水平井近井渗流规律。采用保角变换和迭代法求解该问题。通过与范子飞、宁正富方法的比较，对压裂水平井生产参数的优化进行了研究。分析了启动压力梯度和裂缝簇数对体积压裂水平井产能的影响。采用多元回归分析对影响因素的重要性进行排序。结果表明，起动压力梯度对制冷量的影响最为显著。芦草沟致密储层体积压裂水平井应用实例表明，所建立的层间产能模型可用于体积压裂水平井初始产能预测。因此，通过理论分析和数值模拟，建立的体积压裂水平井产能预测模型对致密储层有效开发具有一定的指导意义。非常规致密油储层特征、改造技术及产能预测
