Abstract: In the exploitation of offshore oil and gas resources, the severe slugging will appear due to the special piping system, gravity, flow, and other factors. The severe slugging will cause secondary hazards and threaten the safety of production. Therefore, it is needed to adopt the method to eliminate the severe slugging. In this paper, OLGA software and PVTsim software were used to simulate the gaslift to eliminate the severe slugging. The results showed that the severe slugging could be eliminate by gaslift in a certain extent. Different gas injection position had different effect to eliminate severe slugging. When the position of gas injection was in the upstream at the bottom of the riser, severe slugging could be eliminated effectively.

摘要： 在海洋油气资源开采中,特殊的管路系统、重力、流量等因素会形成严重段塞流。严重段塞流会引发次生危害,威胁安全生产。因而需要采取方法消除严重段塞流。采用OLGA软件和PVTsim 软件,对气举法消除严重段塞流进行模拟研究。研究结果表明,气举法在一定程度上可以消除严重段塞流,注气位置不同,效果也有一定的差别,注气位置在立管底部的上游位置更能有效地消除严重段塞流。
