Screw drilling tools are devices used in the field of oil exploitation for drilling wells, and are typically used for driving the rotation of a rotor by placing high-pressure liquid between a rotor part and a stator part of the screw drilling tools. However, since it is often operated underground, it is inconvenient to monitor whether it is in a working state in a certain period of time, so that the progress of the drilling progress cannot be known, and in addition, it is inconvenient to replace worn parts in time according to the service life of the rotor part.

However, when the hydraulic pressure in the screw drilling tool is not matched with the actual working time due to mechanical failure (i.e., when the screw drilling tool is not in a normal working state and the internal hydraulic pressure is still maintained at the hydraulic pressure value in the working state), the working time recorded after using the bypass valve will deviate.
