Embodiment Construction

[0033] The push rod three-dimensional hydraulic oscillator is composed of a housing 1, an upper joint 2, a lower joint 3, a one-way valve 4, a transmission part and an oscillating part. One end of the housing 1 is threaded with an upper joint 2. The other end of the terminal thread is installed with the lower joint 3. A transmission member is installed in the casing 1 on one side of the upper joint 2 . The transmission part is composed of a mounting frame 5, a push rod 6, a screw rod 7, a transmission disc B8 and a turntable 9. The mounting frame 5 is an I-shaped frame body, and a turntable 9 is installed in the mounting frame 5 by assembling a short shaft. One end of the turntable 9 is A connecting pin 10 is arranged eccentrically on the end surface, and blades 11 are arranged radially on the other end surface of the turntable 9, and a push rod 6 is slidably installed in the mounting bracket 5 on one side of the turntable 9, and the push rod 6 is in the shape of a strip. One...

Abstract

The invention relates to a hydraulic oscillator, in particular to a push rod type three-dimensional hydraulic oscillator. The push rod type three-dimensional hydraulic oscillator is composed of a shell, an upper joint, a lower joint, a one-way valve, a transmission part and an oscillating part. The upper joint is mounted at the end of one end of the shell in a threaded mode. The lower joint is mounted at the end of the other end of the shell in a threaded mode. The transmission part is arranged in the shell on one side of the upper joint. The one-way valve is mounted in the shell between the transmission part and the upper joint. The oscillating part is mounted in the shell between the transmission part and the lower joint through symmetrically arranged ball bearings, and is connected withthe transmission part. The push rod type three-dimensional hydraulic oscillator has the characteristics of good oscillation effect and high oscillation frequency, solves the problems of the simplex oscillation mode and low oscillation frequency of an existing oscillator, and meets requirements of petroleum drilling.

Description

technical field [0001] The invention relates to a hydraulic oscillator, in particular to a push rod type three-dimensional hydraulic oscillator. Background technique [0002] During the development of the petroleum industry, oilfield drilling is gradually developing from directional wells to extended-reach wells, horizontal wells and horizontal branch wells. When drilling tools are drilling in extended-reach wells, horizontal wells and horizontal branch wells, the drilling tools will Contact and friction with the well wall under the action, the frictional resistance during the drilling process makes it difficult to transmit the pressure on bit, seriously affects the drilling speed, and easily causes the problem of drill string backing pressure. . In order to reduce frictional resistance and reduce pipe sticking accidents, an oscillator is generally used to convert the static friction between the pipe string and the wall into dynamic friction, so as to reduce the frictional ...
