Study on the Sensitivity of Oscillation Performance Parameters of Multi-vortex Hydraulic Oscillator Under Gravity Effect
The use of coiled tubing drilling in drilling operations has the problems of large sliding friction and serious backing pressure. The use of small-sized vortex hydraulic oscillators can effectively improve the drilling pressure transmission efficiency. In this paper, a multi-vortex circumferential hydraulic oscillator model is established to systematically study the influence of structural parameters and vortex number on its working performance under gravity effect. The results show that the oscillation performance of the hydraulic oscillator under gravity effect is highly sensitive to the structural parameters, the number of vortices and other factors. The comparative analysis shows that the oscillation process of the three vortex circumferentially placed oscillator is more stable, the oscillation efficiency is higher, and the oscillation performance is better. The change of the number of vortexes in the multi-vortex hydraulic oscillator will cause the change of the oscillation performance of the hydraulic oscillator. The average pressure drop and the maximum oscillation amplitude of the tool decrease with the increase of the number of vortexes. The research results provide theoretical support for the structural optimization design and application of multi-vortex hydraulic oscillator.
