陕北气田气井油管中防止水合物形成的方法浅析

Superficial Analysis of the Measures for Preventing Hydrate From Forming in Gas Well Pipes in North Shanxi Gas Field

陕北气田的陕44等气井在试采中。均不同程度的在油管中出现水合物冻堵,直接影响气井试采。因此,采取有效措施防止油管中形成水合物,已成为当前开发陕北气田的关键问题之一。本文通过了解现场试采情况。收集国内外有关信息及资料进行分析与计算,提出初浅看法与建议供参考。

The freeze-suffocation caused by the hydrate in the pipes of gas well(such as shan-44)directly affects the testing and production. So it becomes the one of key problems of developing North Shanxi gas field at present to prevent hydrate in the pipes from forming by effective measures. Through inves- tigating the field conditions of testing and production, collecting the similiar imformation and data at home and abroad as well as analysing and computing, the author gives some advices for reference.
