Ground experiment device of rotary directed drilling equipment communication system and using method thereof

Abstract

The invention provides a ground experiment device of a rotary directed drilling equipment communication system and a using method thereof, and belongs to the technical field of petroleum drilling. A main control board of the ground experiment device is connected with a temperature sensor, a three-axial acceleration sensor, a pressure collection and decoding development board, a low-level trigger relay and an LED liquid crystal display screen through a wire; the input end of a positive pressure pulse generator is connected with the main control board; the input end of the negative pressure pulse generator is connected with the pressure collection and decoding development board; the output end of the positive pressure pulse generator and the output end of the negative pressure pulse generator are connected with a normally closed electromagnetic valve; and the normally closed electromagnetic valve is connected with a drilling fluid circulating pump. Pressure pulses detected by a pressure sensor are transmitted to the pressure collection and decoding development board, and then the decoded signals are transmitted to the main control board and a ground upper computer. The ground experiment device of the rotary directed drilling equipment communication system enables the simulation and testing process of the rotary directed communication system to be simpler, more convenient, more rapid, more accurate and more systematized; and the funds consumed by underground experiments can be greatly reduced, and the test period of the underground experiments can be greatly shortened.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to a communication system experimental device and method for rotary steerable drilling equipment Background technique [0002] At present, in the field of oil drilling, rotary steerable drilling technology is the most representative, breakthrough and strategic drilling technology at home and abroad, and has been widely used. The use of rotary steerable drilling technology can realize the real-time control of drilling trajectory by rotary steerable drilling equipment, ensure the consistency and accuracy of the actual drilling trajectory and the set trajectory, greatly improve drilling efficiency and reduce operational risks. [0003] The currently used rotary steerable drilling equipment is a closed-loop control system that integrates machinery, electricity and hydraulics. Its communication system is important to realize the real-time monitoring of downhole signals by the ...
