摘要
针对实际裸眼完井、割缝衬管完井、绕丝筛管完井、裸眼井下砾石充填完井、裸眼预充填砾石筛管完井、裸眼封隔器贯眼尾管及带ECP的裸眼封隔器贯眼尾管完井等七种裸眼系列的水平井完井方式,考虑地层损害和完井方式及完井参数的影响,进行了产能预测数学模型的研究。实例计算表明,其数学模型及计算方法均是正确的,对指导水平井完井方式的选择与完井参数优化设计具有重要的意义。
This paper considered the effect of formation damage and well completion methods and well completion parameters on the productivity of horizontal wells, and studied the mathematical models for the productivity prediction of the horizontal wells with open hole series of completion methods such as real open hole, slotted liner, wire wrapped screen, open hole downhole gravel pack, open hole prepacked gravel liner, perforated liner with open hole packer, perforated liner with open hole packer and external casing packer (ECP), and so on. Example calculations show that the mathematical models and their calculation methods are reasonable. They can be used to guide the optimum selection of well completion methods and the optimum design of well completion engineering.
