According to the high temperature and high pressure experimental device and method, single factor and dual factor control of the temperature and pressure of the logging instrument electronic element or the assembly in the feature filtering and detection process are achieved, and the requirements of high temperature and high pressure joint detection of the logging instrument electronic element or the assembly are met.

Description

technical field [0001] The invention relates to the technical field of applied geophysics, in particular to a high-temperature and high-pressure experimental device and an experimental method for electronic components or assemblies of well logging instruments. Background technique [0002] The detectors of logging tools with multi-dimensional detection function are all arrayed structures, which greatly increases the scale of sensors and supporting electronic systems of logging tools. At the same time, both deep wells and ultra-deep wells are of small diameter, which strictly limits the outer diameter of logging instruments. Only by tightly coupling some components and sensors and working in a high temperature and high pressure environment at the same time can the high integration of arrayed detectors of logging instruments be able to meet the requirements of downhole small size and high reliability. This requires the screening and testing of high temperature and high pressu...
