各种射孔系列完井方式下水平井产能预测研究

本文针对套管射孔完井、射孔套管内绕丝筛管完井、射孔套管内井下砾石充填完井、射孔套管内预充填砾石筛管完井等四种射孔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是可行的,可用于水平井完井方式的选择与完井参数优化设计。

Study on productivity prediction of the horizontal wells with completion methods of perforation series

This paper makes a research on the mathematical model of productivity prediction in view of the four completion methods or horizontal wells of perforation series, such as casing perforated completion, inside casing wire wrapped screen, inside casing gravel pack, inside casing prepacked gravel liner and in consideration of the effect of formation damage, well completion methods and well completion parameters on the productivity of horizontal wells. Example calculation shows these mathematical models and their calculation methods are feasible and can be used in the optimum selection of well completion methods and the optimum design of well completion engineering.
