Abstract
Abstract The torsional impactor can convert the kinetic energy of drilling fluid into high-frequency circumferential kinetic energy and provide it to the bottom drilling tools, thereby eliminating stick-slip vibration, protecting Polycrystalline Diamond Compact (PDC) bit and improving construction efficiency. As the test can not be directly performed and the working conditions of torsional impactor can not be quantified by using existing sensors due to the narrow space structure of the impactor and complex vibration conditions, a method for measuring the operating frequency of torsional impactor was designed based on the adaptive white noise complete set empirical mode decomposition of surface acceleration signal data and wavelet threshold denoising. In this paper, the data processing algorithm is used to implement and carry out the simulation test experiments, and the experimental results show that the method can accurately measure the vibration frequency of the torsional impactor under simulated working conditions, and effectively quantify its working state.
