Abstract

The invention provides a power supply wireless charging module of a well logging instrument. The power supply wireless charging module comprises a wireless charging module. The wireless charging module comprises the components of a pipe housing with a hollow chamber, a charging battery which is arranged at the upper end of the hollow chamber, and a magnetic coupling coil at the lower end of the hollow chamber. The hollow chamber is internally provided with a charging-and-discharging management circuit board. The charging-and-discharging management circuit board is connected with the magnetic coupling coil and a rechargeable battery for performing rectification and stabilizing on the induction current generated by the magnetic coupling coil and performing charging on the rechargeable battery. The charging-and-discharging management circuit board is provided with a field effect transistor. The pipe housing is provided with a Hall magnetic induction switch which is connected with the field effect transistor. A permanent magnet switch is arranged outside for switching on or switching off the Hall magnetic induction switch. The field effect transistor is connected with the rechargeablebattery and the well logging instrument. The power supply wireless charging module has a beneficial effect of ensuring high sealing performance through wireless charging.

Description

technical field [0001] The invention relates to the technical field of well logging equipment, in particular to a power supply wireless charging module of a well logging instrument and a charging stand thereof. Background technique [0002] In the field of deep geological exploration, geological drilling and drilling monitoring are one of the most important means of implementation. In geological drilling (especially small-caliber drilling) measurement, the probes of various logging instruments used are mostly in the shape of pipe rods, and the core circuit of the instrument is packaged in the tube cabin. Various parameters are measured at the measurement depth. [0003] Due to the limitation of the downhole measurement environment, logging instruments need to solve multiple technical problems at the same time, such as instrument power supply, data reading and waterproof sealing. Early logging instruments usually separate the probe from the controller, and the probe part on...
