排水采气工艺技术

Drainage Gas Production Technology

我国气田所处的地质条件比较复杂,再加上长期开采后气井内部出现积水积液现象,影响了气井开采的产量和寿命,同时,长期存在的积液等可能会对开采出的天然气产生污染和损害。排水采气工艺技术作为克服这些问题的技术手段,是气田开发面临的一项重大研究课题,本文首先分析我国气藏的基本地质特点,随后重点对各种排水采气工艺技术进行探究。

The geological conditions of gas fields in China are complicated. The accumulation of water in the gas wells after long-term development affects the production and life of gas wells. At the same time, long-term accumulation of liquids may pollute the natural gas in the area. As a technical means to overcome these problems, drainage gas production technology is a major research topic in gas field development. In this paper, the basic geological characteristics of China’s gas reservoirs were analyzed, and then various drainage gas production techniques were discussed.
