Highly-integrated well logging surface system

摘要

The disclosure discloses an oil well logging surface system, which consists of a depth system, downhole power supplies, a front-end computer assembly, a control panel assembly, an expansion card module, a system power supply, a cooling system and an Electro-Magnetic Interference (EMI) system. The well logging surface system is connected with downhole instruments through a well logging cable, has functions of depth data acquisition, downhole instrument power supply, cable mode control, signal processing, downhole instrument data acquisition, data transmission and the like, may display data acquired by an internal bus on own dedicated display, and may further upload the data to upper computer software for an upper computer to process through a communication line. Different configurations of a switch on the control panel assembly are changed to select a required cable core distribution mode, power supply voltage/frequency and the like to finish various kinds of operation such as well logging, perforation and coring.
