有杆泵井,油-套环空的液体没有泡沫油时,其液体密度容易确定。但油-套环空液体内出现泡沫油时,由于气态液柱的密度比较小,因此,如果仍用常规密度,直接由液面计算压力,则将造成很大的误差,有时计算出的流压比地层压力还高。本文提出的两种方法,是根据笔者的实践,得出的计算泡沫油井压力的简便方法。 Rod pump wells, oil - loop empty liquid foam oil, the liquid density is easy to determine. However, when the foaming oil is present in the oil-annulus liquid, the density of the liquid liquid column is relatively small. Therefore, if the conventional density is still used and the pressure is directly calculated from the liquid level, a large error will be caused. In some cases, the calculated flow Pressure is higher than formation pressure. The two methods proposed in this paper are based on the author’s practice, a simple method of calculating the pressure of foam wells.
