Fushun Liaoning 113001, China) 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 resu !ts 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.
