Abstract
The utility model discloses a rotation-proof tooth type drillable ball injection sliding sleeve which comprises an upper connector, a middle tube and a lower connector. The upper connector, the middle tube and the lower connector are sequentially connected in a threaded mode from top to bottom and sealed. A plurality of side holes and a plurality of shear pins are arranged in the outer wall of the middle tube, and lower connector rotation-proof teeth are arranged on the upper end of the lower connector. A rotation-proof ball seat and a rotation-proof inner sliding sleeve which are connected through threads are arranged in the middle tube, and ball seat rotation-proof teeth are arranged in the middle of the outer wall of the rotation-proof ball seat. Upper rotation-proof teeth capable of being matched with the ball seat rotation-proof teeth are arranged on the upper end of the rotation-proof inner sliding sleeve, and lower rotation-proof teeth capable of being matched with the lower connector rotation-proof teeth are arranged on the lower end of the rotation-proof inner sliding sleeve. According to the rotation-proof tooth type drillable ball injection sliding sleeve, the rotation-proof teeth are arranged in the sliding sleeve so that relative rotation is generated, and drilling, milling and secondary measure reconstruction can be achieved in construction. A maximum circulation channel is provided for production of a large well section.
Description
Technical field
The utility model relates to the tooth-like pitching sliding sleeve that bores of a kind of oil, natural gas extraction instrument, particularly a kind of anti-rotation.
Background technology
Horizontal well can effectively improve well yield, improve the reserves use rate, reduces integrated cost, has therefore become one of oil gas field enterprise-essential development scheme.For low permeability oil field, acidifying, fracturing reform are the important means of reservoir stimulation.
The segmentation modification measures is again method commonly used at present, in the horizontal well in segments transformation process, needs to use the sliding sleeve switch instrument, by pitching, make ball be seated at ball seat, form sealing, oil pipe is suppressed, and cuts off shear pin, the promotion sliding sleeve is descending, exposes the measure passage, finishes modification measures.But this instrument is used for the sliding sleeve switch of horizontal well acidifying, pressure break and also has following problem in application: 1. when carrying out the multistage measures to reform, because multistage sliding sleeve fuse internal diameter is too little, diminish thereby cause producing passage, to such an extent as to influence exploitation effect to target zone to a certain extent; 2. because this time tubing string belongs to disposable tubing string, after transformation is finished, when thinking again target zone to be transformed, need trip out original tubing string, carry out oil-gas Layer again and transform operation, difficulty of construction is big, and the cycle is long.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of increase and produces passage, can carry out the tooth-like pitching sliding sleeve that bores of anti-rotation of secondary measures to reform.
To achieve these goals, the technical solution of the utility model is as follows:
The tooth-like pitching sliding sleeve that bores of a kind of anti-rotation, comprise top connection, intervalve and lower contact, described top connection, intervalve and lower contact are threaded successively from top to bottom and form sealing, described intervalve outer wall is provided with a plurality of side openings and a plurality of shear pin, described lower contact upper end is provided with the lower contact antiturning pitch, described intervalve inside is provided with by the anti-rotation ball seat that is threaded and anti-rotation inner sliding sleeve, described anti-rotation ball seat outer wall middle part is provided with the ball seat antiturning pitch, described anti-rotation inner sliding sleeve upper end is provided with the last antiturning pitch that can cooperate with the ball seat antiturning pitch, and described anti-rotation inner sliding sleeve lower end is provided with the following antiturning pitch that can cooperate with the lower contact antiturning pitch.
Described anti-rotation ball seat inwall is formed with ramp and lower inclined plane in both sides up and down.
Described anti-rotation inner sliding sleeve is two ends and intervalve formation sealing up and down.
The endoporus of described lower contact is up big and down small taper.
The tooth-like pitching sliding sleeve that bores of anti-rotation of the present utility model by antiturning pitch is set, prevents that sliding sleeve inside from producing relative rotation, and can be implemented in the construction to bore to mill and the secondary measures to reform, for the production of long well section provides circulation to greatest extent.
Description of drawings
The tooth-like structural representation that bores the pitching sliding sleeve of anti-rotation that Fig. 1 provides for the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, the tooth-like pitching sliding sleeve that bores of a kind of anti-rotation of the present utility model, comprise top connection 1, intervalve 2 and lower contact 10, described top connection 1, intervalve 2 and lower contact 10 are threaded successively from top to bottom and form sealing, described intervalve 2 outer walls are provided with a plurality of side openings 11 and a plurality of shear pin 7, described lower contact 10 upper ends are provided with lower contact antiturning pitch 9, described intervalve 2 inside are provided with anti-rotation ball seat 13 and the anti-rotation inner sliding sleeve 14 by being threaded, described anti-rotation ball seat 13 outer walls middle part is provided with ball seat antiturning pitch 4, described anti-rotation inner sliding sleeve 14 upper ends are provided with the last antiturning pitch 5 that can cooperate with ball seat antiturning pitch 4, and described anti-rotation inner sliding sleeve 14 lower ends are provided with the following antiturning pitch 8 that can cooperate with lower contact antiturning pitch 9.
Described anti-rotation ball seat inwall is formed with ramp 20 and lower inclined plane 21 in both sides up and down.
Described anti-rotation inner sliding sleeve is two ends and intervalve 2 formation sealings about in the of 14.
The endoporus 19 of described lower contact 10 is up big and down small taper.
The tooth-like pitching sliding sleeve that bores of the anti-rotation that the utility model provides, its course of work is as follows:
Ball is dropped into by the instrument epimere, and it drops on the ramp of anti-rotation ball seat 13 along top connection 1, thereby makes these anti-rotation ball seat 13 inner hypomeres of going up separate.Along with liquid continuous this anti-rotation sliding sleeve top that enters, the thrust that ball is subjected to increases gradually.When thrust exceeded the break limit of shear pin 7, uniform shear pin 7 was all cut off, anti-rotation inner sliding sleeve 14 and anti-rotation ball seat 13 mounted thereto under the promotion of ball whole shift to intervalve 2 the bottom.Along with relatively moving of anti-rotation inner sliding sleeve 14, the a pair of sealing ring 3 on anti-rotation inner sliding sleeve 14 tops moves past the side opening 11 on the intervalve 2, when the side opening 11 on the intervalve 2 exposed fully, the jump ring 6 on the anti-rotation inner sliding sleeve 14 was opened, and was stuck in the jump ring groove 15 of intervalve 2 bottoms.When needs enlarge the production passage or carry out the secondary measures to reform, follow under the revolving force effect at the pressure that bores illing-drilling head, the following antiturning pitch 8 of anti-rotation inner sliding sleeve 14 lower ends and 9 engagements of the lower contact antiturning pitch of lower contact 10 upper ends, the ball seat antiturning pitch 4 of anti-rotation ball seat 13 and 5 engagements of the last antiturning pitch of anti-rotation inner sliding sleeve 14, realize anti-rotation, thereby the drillability that can bore sliding sleeve is opened fully.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but this embodiment is included within the scope of the present utility model.
