[0029] Due to the increasing amount of deep well drilling and high temperature drilling projects, the underground temperature will exceed 290℃, even reach 300℃, which is far beyond the temperature test range of the existing high temperature roller furnace. The existing high temperature roller furnace can no longer meet the needs of deep well drilling; in addition, different temperature rise curves have a significant impact on the aging performance of drilling fluid. It is necessary to control the heating rate of the roller furnace to obtain different temperature curves of the samples, and provide key technical data for the traceability of the high temperature aging temperature data of the sample test. The existing roller furnace usually cannot provide a sufficient temperature range and precise temperature rise control, which limits the research on the aging performance of samples such as drilling fluid under different temperature conditions.

[0033] Belt heating plate 1, two groups of high-power belt heating plates 1 are installed on the opposite side walls in the heating space, the belt heating plates 1 are located above the support shaft group, and are arranged with the same length as the support shaft group in the length direction, and are arranged with the same height as the aging kettle 21 in the height direction. This structure can make the aging kettle heated more evenly;

[0034] A control box 3 is connected to one side of the outer wall of the heat preservation box 2, and the control box 3 has a control system, a display screen and a thermostat 81, and the thermostat 81 is electrically connected to the belt heating plate 1; the display screen, the thermostat 81, the temperature sensor 8 and the fan 9 are all electrically connected to the control system, and the display screen displays the temperature rise trajectory curve.

The control box 3 is installed on the right side of the heat preservation box 2, and the temperature of the right outer wall is relatively low, which can effectively reduce the working environment temperature in the control box.

[0040] The temperature sensor 8 is a thermocouple, which may be a J-type thermocouple.

[0041] In the utility model, the control system receives information from the temperature sensor and transmits operating instructions to the temperature controller 81.
