渤Drilling rigs developed a new explosion-proof torque meter to extend the service life by 3 times

[ China Instrument Network Instrument R&D ] After one and a half years of on-site application, the new generation of explosion-proof torque meter TNY-V developed by Bohai Drilling Drilling Co., Ltd. has completed more than 20 wells in the gas storage of Jiangsu West Gas Pipeline. Service, demonstrating technical advantages in torque monitoring and safety explosion protection.

Torque meters are tests for the perception of torsional moments on various rotating or non-rotating mechanical components. The torque sensor converts the physical change of the torque into a precise electrical signal, which can be applied to the manufacture of viscometers, electric (pneumatic, hydraulic) torque wrenches, which have the advantages of high precision, fast frequency response, good reliability and long life.

In the process of casing, due to the volatile gas such as natural gas in the offshore platform or land operation, when the gas encounters the instrument circuit board or components, it may cause explosion in the well and the drill floor.

In order to solve this problem, Bohai Drilling Drilling Technology Co., Ltd. organizes technicians to select the program for the explosion-proof mode of the instrument, and compares and analyzes the advantages and disadvantages of positive pressure type, intrinsically safe type and explosion-proof type to select the most suitable one. Program.

The explosion-proof torque meter developed by Bohai Drilling and Drilling Technology Co., Ltd. can ensure the accuracy of each casing buckle and avoid accidents caused by over-tightening or loosening of the buckle. The explosion-proof torque meter adopts the intrinsically safe explosion-proof design, and the outer casing is made of aluminum plate metal material. The upper machine and the lower position machine are integrated into the chassis, and the circuit board is redesigned and modified. The core wire connector of the instrument adopts explosion-proof joint, and the upper computer adopts touch liquid crystal display to meet the design requirements of safety, stability, lightness and portability. On January 9, 2017, the explosion-proof torque meter was granted the national utility model patent, which filled the technical gap of such products in China.

The successful development of the new explosion-proof torque meter expands the range of use of the torque meter and can be widely used in offshore platforms and international high-end markets. At present, the new explosion-proof torque meter has been applied in 10 wells. Compared with other types of torque meters, it is easy to operate, portable and has a service life of 3 times, which effectively improves the construction quality of the casing.
