Well hole drilling system

Abstract

The invention provides a well hole drilling system. The well hole drilling system comprises a drilling machine, a computer processing system and a drilling tool. The drilling machine and the computerprocessing system are located on the ground, and the drilling tool is connected with the drilling machine to extend downwards into a stratum shaft below the ground and arrive at the bottom of the shaft. The drilling tool is composed of a drilling rd, an inclination sensor, a controller, a steering device and a drilling bit. The drilling machine is used for rotating the drilling rod and driving thedrilling bit to rotate, and drilling fluid is supplied through the drilling rod to lubricate the drilling bit and wash rock waste. Force can be applied to the drilling rod, a well hole is guided to advance according to the preset direction, the controller can transmit control signals to the steering device, and the control signals comprise information used for guiding the drilling bit to achievedrilling in the preset direction and guiding the steering device to achieve driving. The controller can further guide the steering device to apply compensation force to the drilling rod, and the drilling direction of the drilling bit is prevented from deviating from the preset direction. The inclination sensor is arranged in the drilling rod and connected with the controller to measure the inclination angle of the position, where the inclination sensor is located, of the drilling rod, and the inclination sensor can effectively control the drilling direction of the drilling bit so that the drilling bit can achieve drilling according to the preset direction.

AI Technical Summary

Benefits of technology

This new technology helps control how much it's going down into oil or gas boreholes better by controlling its orientation at different points along their way through an underground tunnel called a hole. It also prevents any deviation during drilling when needed for certain directions.

Problems solved by technology

The technical problem addressed in this patented text relates how to maintain accurate control over rotational movement during borehole operations while avoiding deviation caused by interactions with rocks or other materials on top (such as sand).
