Full-bore cementing and fracturing sliding sleeve system

A full-bore cementing and fracturing sliding sleeve system, comprising a plurality of soluble plungers and a plurality of sliding sleeves;

• wherein
• the soluble plunger comprises a soluble ball, a rubber cylinder, two pressure ring assemblies, a wedge-shaped body, a slip, a ball seat, a body tube, an elastic tube and a front seat;
• an opening is arranged at a top of the ball seat, an inner wall of the ball seat is provided with a step for clamping the soluble ball, an outer wall of a bottom end of the ball seat is in threaded connection with the body tube, starting from the ball seat, the pressure ring assembly, the rubber cylinder, the pressure ring assembly, the wedge-shaped body, the slip and the elastic tube are sequentially sleeved outside the body tube, the wedge-shaped body is fixed on the body tube by a plurality of first shearing pins in a circumferential array, an outer wall of the wedge-shaped body adapts to an inner wall of the slip by an inclined plane, the elastic tube is fixed on the body tube by a plurality of second shearing pins in a circumferential array, the front seat is in threaded connection with a bottom of the body tube, a plurality of elastic sheets are arranged on an outer wall of the elastic tube in a circumferential array, a bottom end of the elastic sheet is in an acute angle structure, a top end of the elastic sheet is in an obtuse angle structure, and a strip-shaped groove penetrating through the elastic tube is arranged on each of two sides of the elastic sheet;
• a clamping groove is arranged on an inner wall of the sliding sleeve, a bottom end of the clamping groove is in an acute angle structure, the plurality of sliding sleeves are assembled together in the order of gradually increasing lengths of the clamping grooves from top to bottom, and the clamping groove is used to clamp an elastic sheet corresponding to the soluble plunger.
