Analysis Model and Application of Constant Flow Pressure in Condensate Gas Well in Dual Media Formation
LI Xiao-ping,et al.(Daqing Petroleum Institute,Daqing 163318,China)
In the process of condensate gas well production,formation fluid may have complicated phase change.Condensate oil depositing in bottom hole may pollute the bottom seriously and reduce production.In order to solve this problem,condensate gas wells are mostly produced in constant flow pressure status.Thus this paper changes the conventional constant production well test analysis theory and constructs a constant flow pressure model which is adaptable for condensate gas well test.It plots well test theory chart suitable for condensate gas well test analysis.This model can interpret formation parameters through production of condensate gas well,and can predict productivity.The paper gives relative case of application.
