The staff can arbitrarily input the well inclination and the gravity tool (within the range) surface position, and the automatic vertical drilling tool will tilt to the set posture. Given the downhole rotary table or top drive speed (within the range), the automatic vertical drilling tool will generate a push force according to the calculation of the internal control system and automatically drop the inclination to the vertical state. The display will display the push force value, well inclination, and tool surface value, and the printer can also be connected to print data. During the test, the well inclination angle and tool surface input during the test are consistent with the scale and dial indication values ​​of the vertical drilling tool on the test system. During the test operation, the vertical drilling tool has an appropriate movement speed. After multiple tests, it is stable and reliable, and the test purpose and effect are achieved.
