摘要
FIELD: hydraulics.;SUBSTANCE: invention relates to an integrated device for sealing wells, performing underground blasting for loosening and water injection in deep wells. The combined device comprises a capsule plug, an outer capsule, an inner capsule, a tube for injecting water into the capsule, a tube for injecting water into a borehole, and a cone plug. The two ends of the outer capsule and the inner capsule are respectively secured to the capsule plug and the cone plug; the capsule plug, the conical plug, the outer capsule and the inner capsule form a closed, hollow cylindrical cavity. The middle part of the capsule plug is provided with a first opening section, and the middle part of the conical plug is provided with a second opening section; the middle part of the inner capsule is a hollow conduit, and the two ends of the hollow conduit correspond to the first opening section and the second opening section, respectively. The borehole water injection tube passes through the hollow cylindrical cavity, and the two ends of the borehole water injection tube respectively pass through the upper ends of the capsule plug and the cone plug; a part of the pipe for pumping water into the borehole, located in the hollow cylindrical cavity, is telescopically wound on the outside of the inner capsule. The tube for injecting water into the capsule passes through the capsule plug and into the hollow cylindrical cavity.;EFFECT: increased efficiency of the device and implementing the integration of sealing wells, water injection and blasting.;10 cl, 4 dwg
