Abstract

The present invention relates to the technical field of petroleum drilling, in particular to a performance evaluation test platform and method for a non-contact transmission system, including a remote monitoring platform and an electric control cabinet, and an adjustable temperature and pressure for simulating an underground high-temperature and high-pressure environment The high-temperature and high-pressure test chamber; the high-temperature and high-pressure test chamber includes an electric heating furnace and an air booster pump, and the high-temperature and high-pressure test chamber is provided with a rectification adjustment circuit and a signal loading circuit located in the underground environment in the input end of the non-contact transmission system to be tested and the transmitting coil, as well as the receiving coil and signal receiving circuit located in the downhole environment in the output end; the high temperature and high pressure test chamber is also provided with a rotating platform for driving the output end to rotate to simulate the downhole rotation condition; The analog load at the output end of the non-contact transmission system is detected, and a detection circuit for collecting the voltage, current and signal at the input end and output end of the non-contact transmission system to be detected.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to a performance evaluation test platform and method for a non-contact transmission system. Background technique [0002] Non-contact power transmission, also known as wireless power transmission, wireless power transmission refers to the conversion of electric energy into other forms of relay energy (such as electromagnetic field energy, laser, microwave and mechanical waves, etc.) The relay energy is converted into electrical energy through the receiver to realize wireless energy transmission. [0003] Non-contact power transmission transmits power and signals in a non-contact manner through electric field coupling, which solves the problems of energy supply and information interaction between rotating parts in rotary steerable systems. The efficiency of non-contact power transmission is determined by the coupling coefficient of the transmitting coil and the receiving ...
