随着油气田的不断开发,地层压力系数也逐渐降低,因此人们对气井作业过程中的储层保护也越来越重视。在气井酸化、压裂等作业后,通常采用下入气举阀进行氮气气举完成气井入井液的快速返排,气举阀设计已经日趋成熟,但在现场作业过程中,仍然存在气举阀不能有效关闭造成气举“短路”的情况,由于气举阀的调试工作都是在地面进行,与气举阀在井下的作业工况存在较大差别,因此在气举阀设计中也要综合考虑气井产水量和设备处理能力等多方面因素,使设计更趋于合理。
With the continuous development of oil and gas fields, the formation pressure coefficient also gradually decreases, so people pay more and more attention to the reservoir protection during gas well operation. Gas wells in the acidification, fracturing and other operations, the commonly used under the gas lift valve to complete gas well into the well fluid back to the row, gas lift valve design has matured, but in the field of operation, there are still gas lift valve Can not effectively shut down the air caused “short circuit ” situation, the gas lift valve commissioning work is carried out on the ground, and gas lift valve in the downhole operating conditions there is a big difference, so in gas lift valve design To comprehensively consider the gas well water production and equipment handling capacity and many other factors, so that the design tends to be more reasonable.
