摘　　要：水合物的形成会造成堵塞,影响气田的正常开发。苏里格气田经过多年试验探索,形成了以井下节流技术为主体,辅助以井口缠绕保温层、管线深埋等措施成功地解决了水合物堵塞,但在特殊情况下还需要注醇和加热炉加热的方法进行水合物防治和解堵。本文根据苏里格气田的特点和水合物防治存在的管理难度大、含醇污水难于处理的问题,提出了涡流管技术应用于苏里格气田地面管线防治水合物的思路。The forming of natural gas hydrate may lead to plugging and influence the development of gas field.Through several years experimental exploration,assisted by wrapping insulation layer to well head and deep buried pipeline,an agent technology of downhole choke is formed to prevent the generation of hydrate in SULIGE gas field.But under the special condition,alcohol injection and heating furnace are still needed to prevent the generation of hydrate or remove the plug.According to the features of SULIGE gas field and difficulties in hydrate prevention,such as sewage containing methanol treatment and so on,this paper put forward a new thinking of applying vortex tube technology in ground pipeline hydrate prevention in SULIGE gas field.
