利用生产动态资料计算启动压力方法研究

A New calculation method for start-up pressure based on dynamic data

针对传统的计算启动压力方法存在的不足,从低渗透油藏的渗流运动方程出发,建立了启动压力与生产压差的关系,结合油藏实际生产动态数据,可以计算出启动压力梯度。现场应用实例表明,利用生产动态资料计算启动压力梯度的方法相对简单、快捷,并且能够有效地为现场措施调整提供决策参考。

Aiming at the problems in the traditional methods for calculating start - up pressure, the relationship be- tween start- up pressure and production pressure difference was established based on the seepage flow equation for low permeability reservoir. And then combined with the actual dynamic data of reservoir,the start - up pressure gradient can be calculated. The application example showed that the method is relatively simple and quick to calculate the start - up pres- sure gradient, and can effectively provide the decision reference for the adjustment of the field measures
