摘要
大牛地地区致密气田气井普遍产液,严重影响了气井的正常生产,正确判断井筒积液是实施排液工艺的重要内容。采用临界滑脱密度法对气井积液进行了判断,结果表明:使用该方法能够正确判断气井积液,与工程实际相符合,并且还可判断出气井发生气液滑脱后不会立即积液,而是当滑脱超过一定程度后才开始积液。
Liquid loading is a common phenomenon during production in tight gas field of Daniudi area, and it seriously affects the normal production of gas wells. Accurate prediction and judgment of the liquid loading of gas wells will provide theoretical basis for dewatering measures. This paper judged the liquid loading of gas wells by using critical slip density method. The result shows that this method can be used to judge the liquid loading of gas wells accurately, and the judgment result is consistent with engineering practice. The method also shows that the gas well will not accumulate liquid immediately except slipping exceeding a certain degree.
