Description

Technical Field

[0001] This utility model relates to the field of oil and gas extraction technology, specifically to a heating component of a fracturing device. Background Technology

[0002] When using a fracturing unit, the fracturing fluid is directly introduced into the fracturing zone using a pump. However, during fracturing operations, especially in low-temperature environments, the temperature of the fracturing fluid has a significant impact on its fluidity and chemical reactivity.

Furthermore, the low-temperature environment may cause some chemical additives to fail to dissolve or react fully, reducing the overall effectiveness of the fracturing fluid. This necessitates a heating component for the fracturing device. Utility Model Content
