Abstract

The invention relates to a continuous wave mud pulse generator. A hydraulic motor is utilized for replacing a high-power motor to provide a driving force, the driving force is greater, the electrical energy consumption is lower, continuous wave signals are generated by swinging a shutoff valve rotor, and the generator works more stably.

Description

technical field [0001] The invention relates to a continuous wave mud pulse generator used in a wireless measuring-while-drilling instrument in petroleum exploration and drilling engineering. Background technique [0002] In drilling engineering, drilling workers and geological engineers need to keep abreast of the working conditions of downhole tools, the shape of the wellbore trajectory, and the formation and bottomhole environmental parameters. Due to the limitation of the radial size of the wellbore (a slender hole) and the working conditions of the well site, it is not easy to realize the real-time transmission of information from the downhole to the surface. At present, the transmission methods that have appeared or are being used include electrical conduction (hard wire system), electromagnetic wave, sound wave and drilling fluid pulse. Due to a series of insurmountable problems in the practical application of hard wire method, electromagnetic wave method and acousti...
