摘要： 在海上油气生产设施中，产油平台占比较高。在海上油气田处理流程中，天然气混杂着井液，一起被携带至生产处理流程。处理后的天然气，一部分用于燃料气用户或者外输，也有相当一部分通过火炬直接燃烧排放。火炬排放造成了大量的空气污染和天然气能源浪费。如何实现天然气回收再利用，是本文考虑的重点。因此，通过对近年天然气回收技术方案的发展分析，分析了天然气增压的几种办法，结合项目总结的经验，制定了几种天然气回收再利用方案。

Abstract: In offshore oil and gas production facilities， oil production platforms account for a high proportion. In the treatment process of offshore oil and gas fields， natural gas mixed with well fluid is carried to the production and treatment process together. After treatment， part of the natural gas is used for fuel gas users or exported， and a considerable part is directly discharged by torch combustion， which causes a lot of air pollution and waste of natural gas energy. How to realize the recovery and reuse of natural gas is the focus of this paper. Therefore， the author analyzes the development of natural gas recovery technology programs in recent years， analyzes several methods of natural gas pressurization， and formulates several natural gas recovery and reuse programs based on the experience summarized in the project.

Key words: natural gas, torch, recycle, reuse
