对于常规连续气举采油而言,由于注气压力和工作阀以下的液柱压力直接作用在油层上,导致生产压差降低等,影响气举井的产量。为弥补常规连续气举采油过程中工艺的不足,本文通过对气举负压泵的结构及工作原理的描述,介绍了一种负压泵连续气举采油技术,该技术是把连续气举与气举负压泵工作特性的有机结合,充分利用气举装置和负压泵的优势,通过地面试验优选出气举负压泵的最佳生产参数,使得该项技术能明显提高油井的举升效率和产量,为人工举升提供了新的方法。
For conventional continuous gas lift production, gas injection pressure and liquid pressure below the working valve directly on the oil layer, resulting in lower production pressure, affecting gas well production. In order to make up for the shortage of conventional continuous gas lift oil recovery process, this paper introduces a negative pressure pump continuous gas lift oil recovery technology by describing the structure and working principle of negative pressure gas lift pump. Air lift negative pressure pump combination of the working characteristics, take full advantage of the advantages of air lift device and negative pressure pump, through the ground test to optimize the negative pressure pump out of the best production parameters, making the technology can significantly improve the lifting efficiency of the well And yield, providing a new way of artificial lift.
