Liquid nitrogen and static crushing agent coupled coal seam fracturing method
ActiveCN119593754Aspeed up the flowstable supportDisloding machinesDrilling compositionThermodynamicsChemical reaction
The invention discloses a liquid nitrogen and static crushing agent coupled coal seam fracturing method. The method comprises the following steps: preparing frozen static crushing agent particles by using liquid nitrogen; the frozen static crushing agent particles are injected into the drill hole along with liquid nitrogen, the liquid nitrogen drives the coal body to generate cracks and continuously expand and develop due to the fact that the low temperature and the liquid nitrogen pressure are gradually increased, and the frozen static crushing agent particles flow into the cracks generated by the coal seam along with the liquid nitrogen; after liquid nitrogen fracturing is completed, the temperature of the coal seam is gradually recovered along with the influence of the ground temperature, frozen static crushing agent particles start to dissolve, at the moment, the static crushing agent and water start to generate chemical reaction volume expansion, and then the static crushing agent expands in the crack to form a static crushing agent expansion area to conduct secondary expansion fracturing on the crack; meanwhile, the static crushing agent expansion area supports the crack, the crack is prevented from being closed under the action of ground stress, and coal seam fracturing is completed. By means of the method, efficient fracturing of the coal seam can be achieved, cracks can be effectively supported, and therefore the follow-up closing condition is reduced, and finally the mining efficiency of the coal seam gas is effectively improved.
