西峰油田油井合理流压确定方法探讨

Discussion of Method of Determining Reasonable Flow Pressure of Xifeng Oilfield

针对西峰油田，提出了求解油井合理流压的具体方法。该方法不但考虑了油、气、水三相流，而且考虑了启动压力梯度、岩石的应力敏感性，对确定不同地层压力，不同含水阶段的合理流压具有一定的借签作用。

In the light of Xifeng oilfield, a specific method is put foward to solve the reasonable flowing pressure of oil wells. This method takes into account not only a three-phase flow of oil, gas and water, but also startup pressure gradient, and rock sensitivity to stress. The method could be use for reference to determine the different formation pressures, and the reasonable flowing pressure at different water-cut stages.
