用活性剂防止气井水化物的形成

Preventing the Formation of Hydrates with Active Agent

随着天然气工业的发展，气体水化物的问题已使天然气的开采、储运、加工工艺日趋复杂化。文中分析了天然气水化物形成的原因，提出了防止水化物形成的各种方法。分析表明：防止井筒内形成水化物的最有效方法是在气水混合流中添加乙醇或电介质。

With the development of natural gas industry, the gaseous hydrates have made the pro duction, storage and processing technologies complicated. This paper analyzes the genesis of gaseous hy drates,and gives several methods for preventing the formation of hydrates. Analyses show that more effec tive method is ethanol or dielectric added in the mixed stram of gas-water.
