Mechanical hydraulic type switchable fracturing slide sleeve

The utility model relates to the technical field of oil production engineering, in particular to a mechanical hydraulic type switchable fracturing slide sleeve which is used in segment multistage fracturing operation of a horizontal well. The mechanical hydraulic type switchable fracturing slide sleeve comprises an upper connector, a slide sleeve body, a lower connector, a fixing dowel, sealing rings, vulcanized rubbers and a cutting dowel, wherein the upper connector and the lower connector are in thread connection and fixed through the fixing dowel, the upper portion and the lower portion of the slide sleeve are in sealing connection with the upper connector and the lower connector through the sealing rings, and the slide sleeve and the lower connector are fixed through the cutting dowel, rectangular spraying holes are formed in the lower connector and distributed evenly along the circumferential direction, the vulcanized rubbers are directly vulcanized on the lower connector, the outer diameter of the upper portion of the slide sleeve is different from that of the lower portion of the slide sleeve, a groove is formed in the slide groove, and a spring claw is arranged at the upper end of the slide sleeve. The mechanical hydraulic type switchable fracturing slide sleeve is designed for increasing fracturing segments, sanding size and fracturing pertinence of a segment multistage fracturing operation pipe column of the horizontal well, is mainly used for segment multistage fracturing operation of uncased holes or the cementing horizontal well, and has the advantages of being accurate in positioning, high in operation efficiency and large in inner drift diameter.
