针对让纳若尔油田部分气举井由于井筒中存在长段塞流,导致流压、流温曲线拐点过多,无法直观、准确的分析气举井工作状况,特别是对于喷射气举井,由于测试工具串无法通过喷射泵测得全井流压、流温参数,导致无法准确判断喷射泵是否正常工作,本文提出了一种四参数气举井工况诊断技术,即除了记录井筒内的深度、压力和温度数据外,还检测甲醇的有无及浓度,从而更准确的判断工作气举阀的位置和喷射泵的工作状况。
In view of the fact that there is a long slug flow in some wellbores of Jeanneau Oilfield, there is too much inflection point of flow pressure and flow temperature curve, so it is impossible to analyze the working condition of gas well well directly and accurately, especially for jet gas well, Because the test tool string can not measure the whole well’s flow pressure and flow temperature parameters through the jet pump, it can not accurately determine whether the jet pump is working properly. In this paper, a four-parameter gas well-well condition diagnosis technology is proposed, Depth, pressure and temperature data, but also detect the presence and concentration of methanol, so as to more accurately determine the position of the working gas lift valve and the working conditions of the jet pump.
