通过同一口井关井后所测得的压力恢复曲线与开井后测得的压力降落曲线进行曲线形态和压力及其参数对比。从理论上阐述压力恢复与压力降落具有相同的功能,在一定条件下可用压力降落试井方法求得地层压力及其参数。减少因恢复不成功使得重复测压对油井产量的影响。
Through the same well after shutting down the measured pressure recovery curve and open well measured pressure drop curve for curve shape and pressure and its parameters comparison. It is theoretically explained that pressure recovery and pressure drop have the same function. Under certain conditions, pressure drop and well test can be used to obtain formation pressure and its parameters. Reduce the impact of repeated manometry on well production due to unsuccessful recovery.
