Abstract
Disclosed is a fracturing device for extraction of coalbed methane in low permeability reservoir. In the disclosure, by controlling the fracturing of fracturing pipes and the sealing of a segmented sealing mechanism for fracturing using a fracturing controller, the fracturing in fracturing holes can be effectively controlled. The segmented sealing mechanism for fracturing in the disclosure can separate each of the fracturing pipes in the fracturing holes separately in a sealed manner respectively, and perform segmented fracturing operations using each of the fracturing pipes, so as to effectively improve the uniformity and thoroughness of fracturing and ensure fracturing ability. In the disclosure, when the sealing operations are performed in each segment, the sealing effect of each segment can be ensured, and the sealing efficiency can be ensured, so that the fracturing ability of each segment of fracturing is improved to ensure the fracturing effect.
