Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fracturing pipe pushing, and particularly relates to a tracked high-pressure water fracturing pusher. BACKGROUND

[0002] As an important mining method, high-pressure water fracturing technology has significant advantages in coal mining. The core of this technology is to use pre-existing fractures in the borehole as guide fractures. Under the combined action of surrounding rock stress and water injection pressure, the direction of coal seam fracture is guided, thereby achieving precise control of the coal seam. In this way, the coal seam fracture can be made to follow the predetermined direction instead of following the natural texture of the coal seam, which helps to improve the precision and safety of the operation, reduce production costs, protect the geological structure, and reduce environmental impact. In addition, this technology can also improve the permeability of the coal seam, creating more favorable conditions for subsequent gas well extraction, and is of great significance to improving the efficiency and quality of coal resource mining.

[0003] In the application process of high-pressure water fracturing technology, the pushing of high-pressure water fracturing pipes is a key link. However, the traditional high-pressure water fracturing pipe pushing method has many limitations. Traditional pushing usually relies on manual operation, which not only has high labor intensity and low efficiency, but also cannot guarantee the stability of pushing. In the complex underground environment of coal mines, manual pushing is also easily affected by factors such as roadway conditions and space limitations, increasing the difficulty and risk of operation. In addition, manual pushing cannot achieve precise control of the pushing speed and angular position of the fracturing pipe, which may result in unsatisfactory fracturing effect and affect the efficiency and quality of coal mining.
