气举阀排液技术在苏里格气田的应用

Application of Gas Lift Valve Drainage Technology in Sulige Gas Field

苏里格气田产水气井数量的不断增多,给气田的安全平稳运行带来了诸多危害。为确保气田产能的稳定发挥,在现场展开不同系列的排水采气措施试验。介绍气举阀排液技术工艺原理,分析评价现场实施效果。实践表明,应用该技术有助于提高储层改造液返排率,且在后期生产中可以实现气举重复利用。

With the increase of gas wells in Sulige oil field, a lot of harm is produced in operation. Different series of drainage measures are carried out to ensure stable play in gas field capacity. This thesis also introduced the tech- nical principle of gas lift valve discharge technology and analyzed the actual effect in production in Sulige gas field. The results showed that gas lift valve drainage technology can effectively improve the flow back rate reservoir fluid, and can be reused in late production.
