Drilling construction practice in complex strata with frozen soil in the no man's land of northern Tibet Plateau
摘要
Abstract
The no man's land in northern Tibet Plateau has a high altitude and harsh climate,and it is difficult to ensure the transportation of construction materials.During the drilling process,problems happened such as thawing and collapse of frozen soil,strong cementation and hole shrinkage in mudstone,continuous breakage and water-gushing in long holes,and so on.In view of this,technical measures are taken to solve the problems in the drilling process such as optimization of drill assembly,flushing fluid systems,drilling tools and equipment,and the use of short-stroke dry drilling,gravity plus rod,follow-up pipe drilling,and drainage pressure relief.The project team has accumulated some experience of drilling construction,which provids effective geological drilling data and physical core data for the survey of energy resources in this region.关键词
