摘　　要：随着气井带压作业新技术的提高,气井带压作业技术得到广泛应用。它最大限度地保持了产层的原始状态、提高产能和采收率,但也可能发生油管内堵塞失效、水合物、卡瓦失效、油管落井、飞出、弯曲、拉断等风险,尤其天然气井水合物的影响最为严重,本文通过水合物形成的原因、产生的危害以及控制消减措施,有效防止带压作业井筒内冰堵的产生。With the improvement of pressure operation technology,pressure operation technology of gas well has been widely used.It maximally keep the original state of reservoir,increase production capacity and recovery ratio,but may also occur within the tubing plugging failure,hydrate,slip,tubing fall well,fly out,bending,tensile,such as risk [1],especially the influence of gas well hydrate is most serious,in this paper,the causes of the formation of hydrate,the harm and control cutting,Effectively prevent the production of ice blocking in the wellbore with pressure.
