Heat radiation-storage device and method for large power device in logging instrument

Abstract

The invention discloses a heat radiation and storage device for a large power device in a logging instrument, and belongs to the field related to logging technology. The heat radiation and storage device comprise a heat conducting pedestal, a heat conducting cover plate, a heat conducting pipe and a heat absorbent module; the heat conducting pedestal is mounted in the surface of the large power device, one end of the heat conducting pipe is tightly fit with the heat conducting pedestal and fixed by the heat conducting cover plate, the other end of the heat conducting pipe is inserted into a heat absorbent housing and makes direct contact with a heat absorbent in the casing, and the heat absorbent housing uses a heat absorbent end cap to seal the heat absorbent therein. The invention also discloses a corresponding method. Heat of the large power device can be directly introduced into and stored in the heat absorbent through the heat conducting pedestal and the heat conducting pipe in the heat conduction manner, a heat transfer process is omitted, heat is transferred and stored more efficiently, the temperature rise rate of the large power device in the logging instrument can be effectively inhibited, and the heat radiation problem of the large power device during long-term high temperature down-hole work can be solved.

Description

technical field [0001] The invention belongs to the related field of well logging technology, and more specifically relates to a heat dissipation and heat storage device for a high-power device in a well logging instrument and a method thereof. Background technique [0002] Well logging is a very important link in oil extraction, and logging instruments, as professional measuring instruments used in oil well logging, directly affect the results of oil well surveying. Using well logging equipment to detect mines can effectively collect various physical information in the underground environment, such as force, heat, nuclear, etc., and then analyze these data information to effectively explain the thickness and position of oil and gas layers within the oil field, and further determine the relationship between Some performance parameters related to mining. [0003] Retrieval shows that in the prior art, the typical heat dissipation structure of high-power devices in the loggin...

AI Technical Summary

Problems solved by technology

With the increasingly harsh working environment of logging tools, the temperature of some logging environments has reached above 200°C, and the above heat dissipation structure is still difficult to meet the heat dissipation requirements of high-power devices in logging tools
