Description
Technical field
The present invention relates to fractured horizontal well wellhead assembly technical field, more particularly to a kind of multifunctional well head automatic ball-throwing dress
Put.
Background technology
In recent years, the large-scale application with staged fracturing of horizontal well technology at home, low-permeability oil deposit fractured horizontal well
Important breakthrough is achieved in terms of renovation technique, also the very big development efficiency and recovery ratio that improve shale gas.Staged fracturing well
Mouth not only carries the functions such as huge discharge pressing crack construction, well control, and substantial connection equipment and the safety of workmen.But mesh
Before, the pressure break special high-pressure rig tool of domestic Staged Fracturing Technique In Horizontal Wells complete sets of Techniques is more based on manually operated, scene
There is very big potential safety hazard and defect in implementation process, be in particular in the following aspects：Two workmens are needed to exist
Wellheadpressure controlled valve, coordinates difficulty big, cumbersome, and labor intensity is high, and reliability is low, easily causes security incident；State
Interior ball injector is complicated, and ball-handling precision is low, it is impossible to continuous pitching, reduces the operating efficiency of pressure break, and pitching number
It is limited, it is impossible to carry out multistage pressure break.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it is an object of the invention to provide a kind of multifunctional well head automatic ball-throwing
Device, with simple in construction, can continuously pitching, operating efficiency is high, the characteristics of can carrying out multistage pressure break.
In order to achieve the above object, the technical solution adopted by the present invention is：
A kind of multifunctional well head automatic ball-throwing apparatus, including matrix 2, rotating disk 4 is provided with the top of matrix 2, and described turns
The center of disk 4 is provided with ratchet 5, is provided with the hole for placing steel ball 3, described matrix 2 and opens on rotating disk 4 around ratchet 5
There is guide pipe 1, rotating disk 4 can be alignd in hole with guide pipe 1 by rotation, and passage, the bottom of guide pipe 1 are provided with the bottom of matrix 2
Portion is connected with passage, and described rotating disk 4 drives it to rotate by drive device.
Described rotating disk 4 is first-class to be set up separately and is equipped with eight holes, and one of them is solid hole.
Described drive device includes the push rod 9 being connected with rotating disk 4, and push rod 9 passes through double toggles 15 and reset with connecting rod 10
Spring 8 is connected, and to be rigidly connected between connecting rod 10 and alignment pin 11, connecting rod 10 is connected with the rotating shaft 12 being assemblied on matrix 2, even
Bar 10 is driven by hydraulic cylinder 14.
The described upper end of matrix 2 is provided with top cover 7, and rotating disk 4 is assemblied in the He of matrix 2 by two thrust ball bearings 6 up and down
Between top cover 7.
The beneficial effects of the invention are as follows：
The present invention rotates rotating disk using ratchet and connecting rod mechanical mechanism, can control continuous pitching, simple and reliable, adopts
Rotated with driven by rotary disc steel ball, reach steel ball and specify placement position to deliver automatically, without the size by controlling steel ball size
Pitching, extends the use scope of ball injector, and improves ball-handling precision, can be under conditions of well head fracturing unit is not stopped
Continuous several times pitching is carried out, while fracturing cost can be reduced.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is top view of the invention.
Embodiment
Detailed narration is made to the structural principle and operation principle of the present invention below in conjunction with the accompanying drawings.
Reference picture 1, Fig. 2, guide pipe 1 aligns with the passage of steel ball 3 on matrix 2 to be connected by screw in the left side of matrix 2, on
Rotating disk 4 of the portion with ratchet 5 is assemblied between matrix 2 and top cover 7 by two thrust ball bearings 6 up and down, top cover 7 and matrix 2
It is bolted, push rod 9 is connected with connecting rod 10 by double toggles 15 and back-moving spring 8, is between connecting rod 10 and alignment pin 11
It is rigidly connected, connecting rod 10 is connected with the rotating shaft 12 being assemblied on matrix 2, and right end cap 13 is connected by bolt with matrix 2 and top cover 7
Connect, hydraulic cylinder 14 is assemblied on matrix 2, the piston rod of hydraulic cylinder 14 is connected by chute with connecting rod 10.
Hydraulic cylinder 14 can both realize control process, simple in construction, and operation is easy.
Remote control can be realized, is conducive to well head automated production, the security of pressing crack construction is improved.
The operation principle of the present invention：
(1) install：Ball injector is arranged on the hydraulic control plug valve of well head pressure break production tree.
(2) ball is filled：Top cover 7 is opened when filling ball, will not have porose entity part and the steel ball passage on matrix 2 on rotating disk 4
Alignment, then by steel ball 3 from small to large successively in the direction of the clock mounted in rotating disk 47 holes in, after the completion of top cover 7.
