Abstract：The high temperature environment in the wellbore hasadverse impacts on the performance and service life of numerous temperature-sensing elements （e.g.sensors and circuit boards）of measurement while driling（MWD） instruments.This paper presents a passive cooling method for temperature-sensing elements of MWD instruments basedonan efficient grapheme thermal conductivity tool.The heat generation of electronic elements in their services was simulated and tested to understandthe performanceof the thermal conductivity tool，andthe test results of simulationand test werecompared.Itis indicated that the overallthermal conductivityof thethermal conductivity tool exceeds 650W/（m⋅K） ，which is 3.27 times that of 6O61 aluminum alloy material. At different laboratorytesttemperatures，the temperature difference between diffrent areas on the surface of the thermal conductive plate after reaching a thermal equilibrium is extremely small， below 3∘C in all costs. By comparing the laboratory test results with the numerical simulationresults，itis found that the temperature curves of the thermal conductive plate at all temperature measuring points under different environmental temperatures are similar in trends，suggesting a good stability in thermal conductivity.The research results provide theoretical reference for the study of high-temperature resistance technology for MWD instruments.
