对于产水气井,水合物的生成不仅妨碍气井的正常生产,而且给恶劣天气下管线的疏通造成很大困难。一般情况下,通过井口加装保温盒或者注醇能够有效预防水合物的生成,注醇的方式更加简便快捷且具有很高的回收率,及时有效的预测不同注醇量情况下气井井口的水合物生成情况对气井正常生产很重要。
For gas wells, the formation of hydrates not only hinder the normal production of gas wells, but also cause great difficulty to clear the pipelines in bad weather. In general, installing a thermal insulation box or alcohol injection through a wellhead can effectively prevent the formation of hydrates. The method of alcohol injection is simpler and quicker and has a high recovery rate, and timely and effectively predicts the hydration of gas wellhead under different alcohol injection rates The formation of matter is very important to the normal production of gas well.
