Problems solved by technology

[0006] The experimental device for testing the performance of the hydraulic oscillator disclosed in this patent document, during the test experiment, inserts and installs the oscillating joint of the hydraulic oscillator into the assembly holes of the installation disc A and the installation disc B, and the hydraulic oscillator The power nipple is inserted and installed in the assembly hole of the installation disc C to realize the clamping of the hydraulic oscillator. The clamping fixed position is relatively fixed, it is difficult to realize the free adjustment of the height, and the flexibility of the test data operation is poor; through Screw in the compression nut to compress the spring to obtain different pressures to simulate the application of drilling pressure, but it is difficult to provide a stable axial thrust for the hydraulic oscillator, resulting in errors in the experimental data obtained from the test and a decrease in the accuracy of the test data

Description

technical field [0001] The invention relates to the technical field of drilling tools, in particular to an indoor testing platform of a hydraulic oscillator. Background technique [0002] The hydraulic oscillator can effectively solve the problems of under pressure and slow ROP in the drilling process. The hydraulic oscillator reduces drilling friction through high-frequency axial vibration, effectively applies drilling pressure, and can effectively increase the ROP. [0003] The main indicators of the hydraulic oscillator are axial vibration force, vibration frequency and vibration displacement. In order to ensure that the newly developed hydraulic oscillator meets the design indicators in the application, it is necessary to test the newly developed hydraulic oscillator indoors to check whether its functionality, reliability and main indicators meet the design requirements. [0004] In order to truly simulate the working environment of the hydraulic oscillator in the well ...
