DC power supply of imaging logging system

Abstract

The invention belongs to the field of logging field acquisition devices, and particularly relates to a DC power supply of an imaging logging system. The DC power supply comprises two power supplies, an output control relay circuit, a voltage measurement circuit, a current measurement circuit, a microprocessor, an output control circuit and an isolation amplifier circuit, wherein output ports of the two power supplies are connected with the output port of the output control relay circuit; the output port of the output control relay circuit is connected with input ports of the voltage and current measurement circuits; the output ports of the voltage and current measurement circuits are connected with the input port of the microprocessor; the output port of the microprocessor is connected with the input port of the output control circuit by an output control potentiometer; and the output port of the output control circuit is connected with the input ports of the two power supplies by the isolation amplifier circuit. The DC power supply has high utilization efficiency and low cost, can supply DC power to both a 5700 logging acquisition system and a 2000 logging acquisition system, and simultaneously has a DC power supply function in the magnetic resonance imaging logging (MRIL)-P of the 2000 system.

Description

technical field [0001] The invention belongs to the field of well logging field acquisition devices, in particular to a DC power supply for an imaging logging system. Background technique [0002] For the 5700 and EXCELL2000 imaging logging systems, the same well often occurs in the international and domestic markets, that is, to measure 5700 items and 2000 items, and one well needs two sets of logging equipment. Two sets of independent logging surface equipments cause great waste in terms of manpower, material resources and financial resources when used. Contents of the invention [0003] The present invention aims to overcome the deficiencies of the prior art and provide a high-efficiency, low-cost, DC power supply for both the 5700 well logging acquisition system and the 2000 well logging acquisition system, and also has the 2000 logging MRIL- The DC power supply of the imaging logging system with DC power supply function at P time. [0004] To achieve the above objec...
