引言
在海洋石油工业开发中，随着海上油、气田开发的不断深人，无论是海上油田还是海上气田普通油气开发工艺流程已经不能满足油、气田对低压力、小流量伴生气的开发要求，导致较多的伴生天然气通过放空系统直接燃烧处理，没有进行回收利用，造成了能源的浪费。为解决该问题，本文以分析海上油、气田开发工艺流程的特点，设计了相应的低压气回收方法，实现了低压力、

常规工艺处理方案
针对海上油田和海上气田的特点需要设计不同
的工艺处理方案来实现油、气田的开发和生产。通常海上油、气田开发的主要工艺流程分为3个步骤：一级分离器系统（高压）；二级分离器系统（中、低压)；三级分离器系统(低压)。对于原油处理工艺：一级分离系统主要分离开液相和气相；二级分离系统主要分离油和水，同时有少量气相析出；三
