The equal wall thickness screw tool is a new type of screw tool developed by Baixin in 2008 on the basis of absorbing the advanced technology of guo9pu. It has obvious advantages in the use of Sitong directional well and medium shallow combination, and shows greater advantages than the silk gauge screw tool in the dumb use of deep well, large displacement well and short radius well.

The inner surface of the stator of the equal wall thickness screw drilling motor is processed into a spiral surface matching the rotor, and then the rubber is vulcanized on the spiral surface to make the thickness of Kizilsu uniform and equal, and the equal wall thickness motor is composed of the matching platform of the carrier. The equal wall thickness motor not only enhances the impact resistance and deformation resistance of the rubber on the inner surface of the stator shell, but also prevents the rubber from aging and dropping during the vulcanization of the equal wall thickness rubber on the inner surface of the stator, so as to achieve the best vulcanization effect and ensure the service life of the screw drilling motor and increase the build rate of the screw drilling tool. The motor has large pressure drop, sufficient power, low transmission speed, high volume efficiency. The pressure drop of each stage is 2-3 times of that of Sutong drilling tool. The total efficiency of motor volume efficiency l rubs the drilling tool is still over% high. If equipped with a roller bit, a higher bit pressure can be applied compared with the conventional drilling tool. It has obvious advantages in short radius horizontal well, deep well and high temperature well.
