Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model blanking plug push loading head embodiment one；
Fig. 2 is the schematic diagram of the utility model blanking plug push loading head embodiment two.
Embodiment
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment one of the blanking plug push loading head of the utility model：
As shown in Figure 1, blanking plug push loading head includes top connection 1, top connection 1 is equipped with radial perforation 14, is easy to and pulling
Device is connected.Top connection 1 includes the epimere 11 equipped with radial perforation 14 and is provided with externally threaded hypomere 12, in epimere 11 and hypomere
Be provided between 12 it is outer turn edge 13, its middle and lower sections 12 extends downwardly and has top connection endoporus.In the external screw-thread of hypomere 12
Lower shell 2 is set with, lower shell 2 includes thread set in the internal thread segment 21 of 1 epimere of top connection and under internal thread segment 21
The rubber sleeve construction section 22 of side.Inwardly it is convexly equipped with inside turn edge 23 in the lower end of lower shell 2, turn edge 23 forms can be with
Make the through hole that blanking plug passes through.
In use, installing rubber sleeve 3 on rubber sleeve construction section 22, it is threadedly coupled top connection and lower shell again afterwards, makes
Rubber sleeve is fitted between the end of top connection 1 and turn edge 23.Wherein, the design internal diameter of rubber sleeve 3 is less than blanking plug pressure
Lid outside diameter 1mm, while as seen from Figure 1, the design internal diameter of rubber sleeve 3 is identical with the design internal diameter of top connection endoporus, and
The aperture of the through hole formed less than turn edge 23.The through hole that turn edge 23 is formed is formed is directed to leading in rubber sleeve by blanking plug
To passage.
Rubber sleeve is pressed therebetween by top connection and the interaction of lower shell and is ensured not when being extruded
Understand play up or down.
The specifically used process of the blanking plug push loading head of the utility model is as follows：, will be stifled during pulling assembled in situ blanking plug
Fill in device insertion pressing and sending head, when the gland of blanking plug is partially exposed to rubber sleeve, rotates blanking plug and firmly compression screws in, make
Elastic deformation occurs for rubber sleeve 3, and the blanking plug screwed in rubber sleeve 3 is subject to the elastic acting force of rubber sleeve 3, with blanking plug
Rotation is fully screwed into rubber sleeve, completes the assembly connection of blanking plug and pressing and sending head.Afterwards by the top connection 1 of pressing and sending head with throwing
After the pulling pawl connection for dragging for device, you can go into the well and carry out the operation for throwing blanking plug.Reach behind injection well downhole flow regulator position by blanking plug deliver into
In the inclined hole of injection well downhole flow regulator, make blanking plug setting in injection well downhole flow regulator.Test winch above carries steel wire makes pressing and sending head and blanking plug by pulling force
Separation, and the tension force that blanking plug is separated with rubber sleeve when caused frictional force makes to rise on test winch reaches 1.2-1.5kN, compared with
Normally having gone up winch load 0.5-0.9kN is higher by 0.5-0.6kN or so, therefore, Tensity size when being risen by testing on winch
It may determine that whether blanking plug normally knocks down injection well downhole flow regulator.
In the present embodiment, rubber sleeve is made using nitrile rubber, and durability is good, rubber after being used continuously 20-30 times
Set still has no noticeable wear or damage.During onsite application, it is desirable to keep cleaning in rubber sleeve to be beaten without greasy dirt, drying, blanking plug
Drag for bar and the cleaning drying of gland periphery.
Even if with the access times increase of rubber sleeve, abrasion is more, and the clamping force of rubber sleeve declines, it is only necessary to is connect by
Head and lower shell screwed apart, the rubber sleeve more renewed.At the same time can also be according to the blanking plug of different model and size more
The rubber sleeve of different model is changed, adapts to the requirement of a variety of different blanking plugs.
Compared with using the pressing and sending head of peg type in the prior art, the blanking plug push loading head in-site installation letter of the utility model
Single, delivery conveniently, pin fracture will not occurs because the reason for concussion during going into the well and cause blanking plug to drop.Even if throw not
Enter blanking plug, the phenomenon that the pulling pawl of throw in catcher will not be caused due to coming off for pin to be classified as occurs.
In the present embodiment, the outside of top connection is provided with annular groove 15, in use, installing the sealing of O shapes in annular groove
The sealing structures such as circle, seal the gap between top connection and lower shell, prevent the liquid of outside from entering in the gap.
The specific embodiment two of the utility model blanking plug push loading head：
As shown in Fig. 2, essentially consisted in the difference of embodiment one：In the above embodiments, rubber sleeve is fitted in
Between the end face of top connection and lower shell turn edge, in the present embodiment, top connection turn edge 3 is provided with top connection 1, under
Lower shell turn edge 4 is set on cylinder 2, rubber sleeve 5 is pressed between top connection turn edge 3 and lower shell turn edge 4.By upper
Mutual assembling between connector 1 and lower shell 2 can realize the removable installation of rubber sleeve 5.
In the above embodiments, rubber sleeve has elasticity and forms elastic rubber set.The endoporus of elastic rubber set constitutes
Elastic clip tieholen, elastic clip tieholen, which has, clamps hole wall.In above-described embodiment, after elastic rubber set is pressed onto position, lower cylinder
The upper surface of body and the outer lug top pressure of top connection coordinate, and prevent the overvoltage to elastic rubber set.
In above-described embodiment, the connection mode between top connection and lower shell in other embodiments may be used to be threadedly coupled
By take it is other in a manner of be attached.
The specific embodiment of the utility model blanking plug pulling device, blanking plug pulling device include throw in catcher, throw in catcher
Including throw in catcher main body and pulling pawl, blanking plug push loading head is installed on pulling pawl, its structure and the knot in above-described embodiment
