Abstract

The invention provides a hydraulic oscillator. The hydraulic oscillator comprises an oscillation module and a control module, wherein the oscillation module comprises a static connector, a stator and a rotor; the rotor is rotationally installed in the stator; the rotor is provided with a rotor center channel and a rotor side channel; one end of the static connector is inserted in the stator and provided with a connector center channel corresponding to the rotor center channel and a connector side channel corresponding to the rotor side channel; the control module comprises a control shell, a controller, a motor telescopic module and a small valve head, wherein the controller, the motor telescopic module and the small valve head are arranged in the control shell; and the controller is connected with the motor telescopic module, and the small valve head is driven to be inserted in the rotor center channel or pulled out of the rotor center channel by controlling the motor telescopic module. The hydraulic oscillator does not work under the composite drilling condition and works under the directional drilling condition, that is, axial force is provided, and meanwhile no influence is caused to other devices.

Description

technical field [0001] The present application relates to the technical field of drilling, in particular to a hydraulic oscillator. Background technique [0002] With the development of the petroleum industry, there are more and more oilfield drilling methods, such as directional drilling, composite drilling, etc. Oilfield drilling is inseparable from hydraulic oscillators, and the existing hydraulic oscillators cannot be used according to different drilling methods.
