低渗气藏中分支水平井的产能预测公式

摘要

采用齐成伟的环形裂缝群复势通式,重复陈小凡等人的推导过程,得出了低渗气藏中分支水平井的产能预测公式。该预测公式可以严格退化为陈小凡等人的低渗气藏水平井产能修正公式。%Productivity formula of branched horizontal wells in low permeability gas reservoir was obtained by inserting general complex potential formula of ring cracks group derived by QI Chengwei into CHEN Xiaofan＇s derivation.The prediction formula can be strictly reduced to productivity formula of horizontal well in low permeability gas reservoir derived by CHEN Xiaofan.
