不稳定生产,即间歇出油是连续气举生产中一个常见的问题,可能会导致液体产量减少甚至是无产量,因此,气举井的稳定性分析与判断对准确预测气举井稳定运行的界限从而降低成本尤为重要。通过分析气举井的流动不稳定性问题,建立了一个气举井模型,在该模型和现有稳定准则的基础上,建立理论气举稳定性图版。该图版显示了系统稳定和不稳定的运行范围,以及运行界限,并与现场数据进行了比较,理论图版与实际结果一致。稳定性图版为设计和操作连续流动气举井提供了很大的帮助。 Unstable production, that is, intermittent oil production is a common problem in continuous gas lift production, which may lead to the reduction or even no production of liquid. Therefore, the stability analysis and judgment of gas lift well can accurately predict the stable operation of gas well Bound to reduce costs is particularly important. By analyzing the problem of flow instability in gas lift wells, a gas lift well model is established. Based on this model and the existing stability criteria, a theoretical gas lift stability chart is established. The chart shows the system’s stable and unstable operating range, as well as the operational limits, and compared with the field data, the theoretical plate and the actual results. Stability charts provide great help in the design and operation of continuous flow gas wells.
