Description

Technical Field

[0001] This utility model relates to the field of shale oil content determination technology, and in particular to a device for determining shale oil content. Background Technology

[0002] Shale oil content is a core parameter for evaluating reservoir economics and development potential. Thermal detection, as one of the mainstream methods, involves programmed temperature rise to crack hydrocarbons and detect the amount of oil and gas released. It is widely used in geological exploration and laboratory analysis. However, clay minerals and organic matter in shale may undergo secondary reactions at high temperatures, causing the measured oil content to deviate from the true value. Parameters such as heating rate and carrier gas flow rate vary greatly among different equipment.

[0003] The patent application CN212228784U discloses a device for determining the oil content of shale oil. By setting an annular groove, and further setting it to be an inclined annular groove, it can quickly collect the condensate generated in the aluminum still and prevent it from flowing back, thereby effectively shortening the dry distillation time, improving the dry distillation efficiency, and saving more energy.

[0004] Traditional heating methods have temperature gradients, and uneven heating of samples can cause premature pyrolysis at the edges while the reaction in the center is delayed. Local overheating may trigger coking side reactions, requiring higher fuel input to maintain the same operating temperature, which directly increases operating costs. Reducing heat loss may also cause local low-temperature zones, resulting in incomplete combustion. Temperature fluctuations affect the stability of the detection. Utility Model Content
