New explosion-proof torque meter developed by the national patent authorization

In the casing process, the pull-up torque needs to be monitored and the torque value recorded. However, in some offshore platforms or on land operations, the wells contain volatile gases such as natural gas. When the gas encounters an instrument circuit board or component and ignites, it can easily cause major accidents in the well and on the drill floor.

In order to solve this problem, the company organizes technical personnel to select the explosion-proof method for the instrument, and compares and analyzes the advantages and disadvantages of positive pressure, intrinsically safe, and explosion-proof, and finally selects the intrinsically safe explosion-proof torque instrument. . This new type of explosion proof torque meter adopts an aluminum plate metal shell structure. The upper and lower position machines are integrated into the chassis. The core wire connector of the instrument is explosion-proof. The upper computer adopts a touch liquid crystal display. These designs ensure the explosion-proof requirements of explosion-proof torque instruments. Taking into account the light and easy operation and other factors. After repeated design and debugging, the performance meets the design requirements.

The successful development of the new explosion proof torque meter has expanded the scope of use of the torque meter and can be widely applied to offshore platforms and international high-end markets. At present, the new type of explosion-proof torque meter has been applied in 10 wells. Compared with other types of torque meters, it is simple to operate, portable, and has a three-fold increase in service life, effectively improving the construction quality of the lower casing.
