Abstract

The invention relates to the technical field of mud generators, in particular to a rotary mud continuous wave generator. The rotary mud continuous wave generator comprises a sealing outer protective cylinder, a shaft seat, rib plates, a flow limiting plate mounting cylinder, a flow limiting plate, mud flow limiting holes, a rotary shaft, a rotary wheel, a blocking connector and an execution drive mechanism, wherein the shaft seat is fixedly mounted at the upper end of the sealing outer protective cylinder, and the flow limiting plate mounting cylinder is fixedly mounted outside the upper end of the shaft seat through rip plates peripherally distributed. The rotary mud continuous wave generator has the advantages that the rotary mud continuous wave generator is reasonable and compact in structure and convenient to use; a control circuit receives electric control signals output by a downhole sensor and drives a motor, the motor outputs power to drive the rotary wheel through the rotation of the rotary shaft, the mud flow sectional area of the mud flow limiting holes can be changed by the damping vanes of the rotary wheel, so that continuous waves are generated in a drill stem, and high transmission rate is achieved; when the rotary mud continuous wave generator enters a well, the execution drive mechanism rotates the damping vanes to increase the flow area of the mud flow limiting holes, good adaptability is achieved, and blocking is prevented.

Description

technical field [0001] The invention relates to the technical field of mud generators, and relates to a rotary mud continuous wave generator. Background technique [0002] In the process of oil drilling, in order to keep abreast of the engineering and geological parameters in the drilling process, a mud pulse generator is usually used; the conventional mud pulse generator obtains downhole information through a solenoid valve mechanism, and then the solenoid valve mechanism drives the mushroom head in the The flow-limiting ring moves up and down, and by controlling the cross-sectional area of ​​the annular space between the mushroom head and the flow-limiting ring, the mud pressure flowing in the drill pipe is changed to generate mud pressure fluctuations; since the mushroom head moves linearly up and down, the output mud pressure fluctuates It outputs fluctuations in the form of intermittent pulses with a very short duration, and the transmission speed is slow; in addition, ...
