Framework structure of nuclear magnetic resonance logging instrument

Abstract

The invention belongs to the technical field of logging instruments, and discloses a skeleton structure of a nuclear magnetic resonance logging instrument. The skeleton structure comprises a tail skeleton, a main control skeleton, a triangular skeleton, an antenna driving module, a front skeleton and a heat absorber module which are axially connected in sequence; the heat absorption body module comprises a main control heat absorption body fixed in the main control framework in an embedded mode, a triangular framework heat absorption body fixed in the triangular framework in an embedded mode, a front heat absorption body fixed in the front heat absorption framework in an embedded mode, and a tail heat absorption body fixedly connected between the tail framework and the main control framework. The antenna driving-triangular framework heat absorbing body is fixedly connected between the triangular framework and the antenna driving module, and the antenna driving-main discharging framework heat absorbing body is fixedly connected between the antenna driving module and the front discharging framework. According to the skeleton structure of the nuclear magnetic resonance logging instrument, the problems that electronic devices at different positions on the skeleton structure are insufficient in heat dissipation capacity and uneven in heat dissipation can be solved.

Description

technical field [0001] The invention belongs to the technical field of logging instruments, in particular to a skeleton structure of a nuclear magnetic resonance logging instrument. Background technique [0002] In the logging tool, the electronic devices and circuit boards in the logging tool are usually fixed on the skeleton structure. Due to the harsh environment of high temperature and high pressure faced by the logging tool in the downhole operation, thermos bottles and The thermal insulation method of the thermal insulation plug provides thermal insulation protection for the skeleton structure and the above-mentioned electronic devices fixed on it. At the same time, the electronic devices in the logging tool will also self-heat during operation, and the heat will be transferred to the endothermic agent at both ends of the skeleton in the thermos through the skeleton heat for centralized heat storage. [0003] However, for nuclear magnetic resonance logging tools with ...
