Abstract This study analysed and discussed the friction wear properties, as well interface evolution behaviour of polycrystalline diamond compact (PDC) under various base oils, through conducting experiments on PDC/Si 3 N 4 with different oils. The lubrication mechanism PDC oils were examined using scanning electron microscopy (SEM), x‐ray energy dispersive spectrometry (EDS), three‐dimensional white light interferometry, Raman spectroscopy. results demonstrated that exhibited best...
With the increasing difficulty of oil and gas resources exploration increase drilling operations in complex geological environments, challenges faced by are also increasing. continuous improvement intelligence MWD/LWD technology downhole instruments, demand for electric energy is In order to ensure normal operation equipment accurate acquisition data, this paper designs a new type external rotor turbine generator, structure parameters generator. Finally, Ansoft Maxwell software used simulate...
In this article, a vortex-induced vibration prediction model of flexible riser conveying two-phase flow, including geometric and hydrodynamic nonlinearity, is established. A van der Pol wake oscillator utilized to characterize the fluctuating lift forces. The finite element method chosen solve coupled nonlinear fluid–structure interaction equations. natural frequencies are calculated validate through comparisons with results from literature. modal analyses show that nonlinearity has...
