气体介质条件下固井技术具有100%的环空顶替效率,实现井壁与套管环空容积全充满,一、二界面胶结质量好;缩短建井周期,节约钻井成本;保护环境等优点。本文结合在川渝地区采取气体介质条件下进行固井施工的元陆5井,对气体介质条件下固井的多项关键技术进行了详细介绍,并对这口井采取气体介质条件下固井技术的应用效果进行了简要总结,对实施气体介质条件下固井设计施工提出了建议和意见。
The cementing technology under gas medium conditions has the efficiency of 100% annulus replacement, realizing full annular volume of the shaft wall and casing, good bonding quality of the first and second interfaces, shortening the drilling cycle, saving drilling costs, and protecting the environment. In this paper, a number of key technologies of well cementing under gas medium conditions are introduced in detail in combination with the well of Yuanlu 5 in cementing under gas medium conditions in Sichuan and Chongqing. The well cementing under gas medium conditions Technical application of the effect of a brief summary of the implementation of gas-solid conditions cementing design and construction put forward suggestions and opinions.
