数值模拟技术在石炭系边水气藏开发中的应用

Application of Numerical Simulation in The Development of Carboniferous Gas Reservoirs With Edge Water

川东石炭系气藏地层水以边水形式存在,气藏的出水类型主要为裂缝水窜型和沿高渗带舌进型。本文对数值模拟方法在川东石炭系边水气藏开发中的特点进行了总结,通过云和寨和万顺场两个石炭系气藏的应用实例可以看出,数值模拟预测的云和寨石炭系气藏云和2井见水时间与实际非常接近,而应用数值模拟开发方案对万顺场石炭系气藏池6井实施排水采气,有效的保护了气藏遭受水侵的危害。

Edge water is widely exist in carboniferous gas reservoirs of east Sichuan,the types of water encroachment contains fissure influx and high permeability zone fingering.This article summarizes the characters of numerical simulation in the development of carboniferous gas reservoirs with edge water.According to the cases of yun he zhai and wan shun chang carboniferous gas reservoirs,we can see that the water breakthrough time of yun he 2 well which was forecasted by numerical simulation is perfectly matched with its real breakthrough time.And using the development plan which obtained from numerical simulation of chi 6 well,we protect wan shun chang gas reservoir from invaded by water encroachment effectively.
