step one: performing heat insulation test on the heat insulation oil sleeve: marking the heat-insulating oil sleeve as a test object, and injecting the heat-insulating oil sleeve into an inner pipe inlet of the test object at the temperature of L1 o C, the thickened oil is used for acquiring continuous heat conduction data and sporadic heat conduction data of the test pipe section i in a test period and sending the continuous heat conduction data and the sporadic heat conduction data to a continuous analysis module and a sporadic analysis module respectively;
step two: carrying out continuous heat conduction analysis on the heat-insulating oil sleeve, obtaining a continuous coefficient of the test object in the test period, and judging whether the continuous heat conduction state of the test object in the test period meets the requirement or not according to the numerical value of the continuous coefficient;
step three: carrying out divergent heat conduction analysis on the heat-insulating oil sleeve, obtaining a divergent coefficient of the test object in a test period, and judging whether the divergent heat conduction state of the test object in the test period meets the requirement or not according to the numerical value of the divergent coefficient;
step four: and (3) distributing critical time length before the heat-insulating oil sleeve works, obtaining the critical time length of the heat-insulating oil sleeve, and transmitting the critical time length of the heat-insulating oil sleeve to the integral test platform.
