Abstract
The invention discloses a ball jumping type sliding sleeve device used under a well, and relates to the technical field of horizontal well completion practice staged fracturing sliding sleeves. The device is put down into the horizontal segment perforation position under the oil and gas well, a sealing ball of a needed specification is thrown from a well opening, when the sealing ball reaches a sectioning ball base of a ball jumping type sliding sleeve, the well opening is pressurized, the sealing ball is located on the sectioning ball base, and pressure difference is formed. When pressure reaches a shearing value of a shearing pin, the shearing pin is shorn, and a jet hole is opened. At the moment, the sealing ball penetrates through the sectioning ball base to continuously move downwards to a sectioning ball base of a next ball jumping type sliding sleeve, the well opening is continuously pressurized, a shearing pin is shorn, and a jet hole is opened. The multiple jet holes can be opened, and multi-stage fracturing is completed. The device is simple in structure, convenient to use, safe and reliable.
Description
Technical field
The present invention relates to the sliding sleeve scrap disassembling technical device field of oil-gas field fracturing completion practice staged fracturing.
Technical background
Differential the sliding in staged fracturing of horizontal well process of using at present.As needs carry out multistage pressure break, need throw at well head the ball sealer of a plurality of different size specifications, at well head, throwing once sealing ball can only pressure break one section.And need to stop ground pump truck and relevant device before each pitching.Downhole tool, in the process of termination of pumping repeatedly, startup pump, very easily causes downhole tool to damage or lost efficacy like this.Easily make fracturing work failure.Cause the waste of fracturing fluid, pressure break sand.
Summary of the invention
Purpose of design of the present invention is that a kind of of design need be thrown ball one time at well head, utilizes not termination of pumping to throw the jet orifice that a ball sealer is opened a plurality of sliding sleeves, realizes multistage pressure break.Avoid downhole tool to damage or lost efficacy, simple to ground operation requirements, operation safe is reliable.Jet orifice adopts independent cemented carbide body, avoids high pressure, high-velocity fluid directly to wash away instrument.
The ball formula sliding bush apparatus that jumps for down-hole, its top connection, sand-blasting drum, lower contact are threaded connection and form shell body jet mechanism; Be positioned at the in-house sliding sleeve of shell body jet and distinguish ball seat and connect and compose sealing mechanism by elastic claw form; Nozzle cage is on sliding sleeve, and sliding sleeve is fixed on sand-blasting drum inwall by cutting off.
Distinguish ball seat of the present invention, sliding sleeve, ball sealer, cut off composition sealing mechanism, the jet mechanism that sand-blasting drum, top connection, lower contact, nozzle form.The present invention compares with background technology has following feature: 1. need throw a ball sealer at well head and can realize multistage pressure break; 2, jet orifice direction is 45 ° obliquely, has avoided high-pressure fluid directly to wash away downhole tool; 3, be designed with the nozzle that is specifically designed to jet, nozzle adopts cemented carbide body, and intensity, flushing resistance are splendid; 4, cut off design below jet orifice, in assembling process, avoid like this sealing ring to be cut off hole and cut off.5, inner lock ring mechanism can guarantee that distinguish ball seat is all the time in softened state.Guarantee the concentric of distinguish ball seat.
Accompanying drawing explanation:
Accompanying drawing 1 is the ball formula sliding bush apparatus general assembly structural representation that jumps for down-hole, down-hole of the present invention
Accompanying drawing 2 ball sealers pass the ball formula sliding sleeve that jumps, and open the structural representation of jet orifice.
The specific embodiment
The ball formula sliding bush apparatus device that jumps for down-hole described in the present invention, structure as shown in Figure 1, down-hole is that top connection 1, sand-blasting drum 2, lower contact 10 are threaded connection and form shell body jet mechanism by the principal character of ball formula sliding bush apparatus of jumping, inner sliding sleeve 6 and distinguish ball seat 7 connect and compose sealing mechanism by elastic claw form, nozzle 3 is enclosed within above sliding sleeve 7, and sliding sleeve 7 is fixed on sand-blasting drum 2 inwalls formation the present invention by cutting off 5.In nozzle 3, jet orifice 4 adopts 45 ° of unhurried current forms; The seal groove bottom of sand-blasting drum is fixing with cutting off.Sliding sleeve adopts the elastic claw form of fluting, and distinguish ball seat adopts three lobes to form an integral body.
When ball sealer 9 is seated on distinguish ball seat 7, by well head, be forced into while cutting off 5 value for shear, ball sealer 9 drives distinguish ball seats 7 and sliding sleeve 6 integral body to move to right.Now, jet orifice 4 is opened.Elastic claw mechanism on sliding sleeve 6 moves to right to lower contact reducing place, the sliding sleeve 6 lower contact reducing place that fixes on.Continue well head pressurization, along with pressure raises, elastic claw is stretched out under 7 effects of distinguish ball seat, and distinguish ball seat 7 and ball sealer 9 spin off completely smoothly from sliding sleeve 3.Because distinguish ball seat 7 is now without any restraint forces.Ball sealer 9 also departs from distinguish ball seat.Distinguish ball seat 7 is stayed in lower contact.Ball sealer 9 continues to come downwards to another and jumps in ball formula sliding sleeve.Keep the constant next one ball formula sliding sleeve that jumps of opening of well head pressure.So, can open a plurality of distinguish ball seats.
