摘要
Abstract
Take the example of ZK2208 in detailed survey project of Yuzhou of Henan Province, with rational well drilling structure, water stop by different diameter casings, well washing by sodium pyrophosphate and CO2 , casing pulling for long term observation hole with drill and jack, the difficulties of casing running, one trial effective water stop, effective well washing and smooth casing pulling have been overcome, a deep hydrogeological hole of more than 1300m in depth has been completed according to the geological design and related regulations.关键词
