The article considers the issue of improving the cost-performance ratio of well drilling through the use of a device for drill and production pipes, which allows for multi-stage hydrostatic pressure testing during preparatory work in the well before liner completion, well lining and other technological operations. The authors present the results of a patent analysis on the problem under study and prove the need to create a device with a simpler design with a reduced probability of breaking and allowing multiple pressure testing of pipes in the well without lifting them to the surface. The article presents a scheme of the device and the technology of its operation in the well. The results of factory tests of a prototype device with a diameter of 105 mm showed its efficiency and practicality for technological processes during the drilling and exploitation of deep oil and gas wells.
