摘　　要：浅层气预防治理是固井技术面临棘手的问题,当稠油油藏浅层气发育,会增加油田开发的难度。文章介绍了针对本区块油田防浅层气热采开发过程中所面临的固井技术难点,结合前期技术研究及现场应用8口井成果,形成较完善的海上防浅层气热采井固井技术。Prevention and treatment of shallow gas is a thorny problem faced by cementing technology.When shallow gas is developed in heavy oil reservoir,it will increase the diff iculty of oilf ield development.In this paper,aiming at the cementing technical diff iculties in the development of shallow gas thermal recovery in this block,combined with the results of previous technical research and f ield application of 8 wells,a relatively perfect cementing technology for offshore shallow gas thermal recovery wells is formed.
