Abstract:
The well CGSD-01 of Donglihu in Tianjin is a geothermal exploration well. The design depth of the well is 4000m and the completion depath is 4051.68m. In order to clean up the blockage of aquifer in the drilling process, the well is flushed by three methods, and pumping tests are carried out twice. This paper mainly describes the well washing and pumping test technology and process of the well CGSD-01, in order to provide useful reference for similar research in the future.
