Method and tool for rapidly crushing oil meter sleeve annulus cement

The tool for rapidly breaking the oil meter sleeve annulus cement is composed of a composite breaking tool and a screw-in type nozzle bin, and an upper connector, an upper mounting hole, a lower mounting hole, a water hole and a drill bit are arranged on a body of the composite breaking tool; a high-frequency sound wave generating bin is installed in a center hole in the center of the interior of the body, and screw-in type nozzle bins can be installed in upper and lower installation holes. The invention further provides a method for breaking the oil meter casing annulus cement through the tool. The method comprises the steps of engineering logging, shaft sealing through a temporary barrier, guiding tracing pipe descending, process pipe column descending, cement breaking, process pipe column lifting, oil-string casing taking-out and the like. The problems of offset cutting, slow footage and long construction period during casing milling of the oil-string casing in the casing taking and replacing construction
