To avoid lost circulation or wellbore instability when drilling fluid circulated downhole after gas drilling, or to shorten drilling cycle and reduce drilling costs, it is recognized that the cementing quality needs to be improved further. 18 dryhole cementing jobs have been tried in 339.7 mm and 244.5 mm holes in Sichuan and Chongqing oil or gas fields and a set of technology for dryhole cementing after gas drilling is developed, including wellbore preparation, casing running, incontinuous liquid slurry injection, etc.

为了避免气体钻井结束后替入钻井液可能引发的井漏、井眼不稳定等复杂情况，缩短钻井周期、降低钻井成本，进一步提高固井质量，在川渝地区探索实践了气体介质条件下339.7 mm表层套管和244.5 mm技术套管共18井次的干井筒固井作业，基本形成了一套气体钻井后干井筒（井眼内为纯气体时的井筒简称为干井筒）固井工艺技术方案与措施。
