油田长期的注采开发,使得地层压力发生变化,加上地层的不均质性和复杂断层等方面的影响,地层压力变得更加复杂。为满足调整井钻井需求,借鉴油藏数值模拟理论,利用油田生产的动静态参数分析储层孔隙压力的变化,建立了一套基本可行的调整井地层压力预测理论、方法和计算模型。该技术在江苏黄珏油田应用,取得一定的效果。

As oilfield long-term injection-production development,the formation pressure has been changed.And the reservoir pressure becomes more complex due to the heterogeneity of formation and the complicated fault.In order to satisfy the requirements of adjustment well drilling,the dynamic and static parameters obtained from oilfield production were employed by using reservoir numerical simulation theory to analyze the changes of reservoir pressure,and a set of practical theory,method and calculation model for formation pressure prediction was set up.The technology has been applied in HuangJue Oilfield,and has obtained the certain effect.
