确定气藏原始地层压力的简便方法

A Simple and Convenient Method for Determing the Original Formation Pressure in Gas Pool

原始地层压力很高的气藏,因预探井发生强烈井喷而失去取得原始地层压力的时机。或因井口装置问题不允许关井求原始地层压力。对此,本文提供了一种简便方法。应用该法,只要在试采中取得两个以上地层压力及累计产量数据,即可反求原始地层压力。

We always loss the chance to obtain the original formation pressure in the gas pool which has a very high original formation pressure, because of strong blow-out happening in a wildcat well, or the well not promised to shut in for measuring the pressure because of the problem of wellhead equipment, for this, this paper presents a simple and convenient method which can be used to reversedly calculate the original formation pressure, only to get more than two of formation pressures and accumulation production data in producing test.
