摘要(Abstract)：
针对大庆长垣外围气井产量低、携水困难,形成井底积液影响生产等问题,提出了用井下节流法防治气井水合物的技术,经现场应用效果较好。井下节流法有效地解决了气井积水影响生产的问题,不仅提高了气井生产时率,而且提高了井口温度,有利于降低积气能耗。
This paper established a kind of technique to control hydrate in gas wells with the application of downhole choke. This technique was developed due to the problems existed in Daqing placanticline, such as low production of gas wells, difficulty in carrying water, liquid storage in bottom hole, and so on. The field tests proved it was effective. This method can solve the problem caused by water storage, improve production efficiency in gas wells, increase temperature at wellhead and decrease energy loss caused by gas storage.
