运用IPR曲线求解地层压力

ESTIMATION OF ESERVOIR PRESSURE BY USING IPR CURVE

以前往往采用不稳定试井的方法求解地层压力及有关地层参数，但这种方法费时费力，而且对某些自喷井又有所局限。为厂解决这些问题，本文根据无因次ＩＰＲ曲线通式￣［１］，推导出求解地层压力的公式；该公式简捷可靠，具有普遍的实用价值，实际应用将会产生较好的经济效益。

The reservoir pressure is related its parameters.They are used to be determined by themethod of unsteady well testing which was time-consuming and not suitable for some flowingwells,To solve these problems , an equation of formation pressure based On dimensionlessIPR curves is deduced. The equation is simple and reliable,and is of practical value. Practicalapplication will result in better economic efficiency.
