The utility model discloses the new gluing core of environmentally friendly closed rotating blowout preventer, it includes actuating sleeve（1）, hexagon socket head cap screw（2）, O-ring（3）, nut（4）, glue core（5）, gluing core cup（6）And bolt（7）, actuating sleeve（1）With gluing core cup（6）Between using some high intensity hexagon socket head cap screw（2）Connection, actuating sleeve（1）With gluing core cup（6）If between by arterial highway fluorubber material O-ring（3）Sealed, glue core（5）Pass through nut（4）It is locked at actuating sleeve（1）Bottom, gluing core cup（6）The bolt of bottom（7）For connecting other parts, the new gluing core of environmentally friendly closed rotating blowout preventer is monolithically fabricated.Gluing cored structure of the present utility model is simple, firm and reliable connection, it is to avoid during the reversion of kelly bar driver drives rotation assembly the problems such as caused thread looseness, seal failure, it is ensured that sealing reliability, service life is improved, makes under balance pressure drilling work more efficiently.
Description
Technical field
The utility model is related to the environmentally friendly closed rotating blowout preventer of under balance pressure drilling, and in particular to environmentally friendly closed rotation is anti-
The new gluing core of spray apparatus.
Background technology
Current under-balanced drilling technology has evolved into ripe, and it finds and reservoir protec-tion and improve the side such as bit speed
The effect in face is also accepted.With developing rapidly for petroleum industry, field of oil drilling using under-balanced drilling technology as
A kind of one preferred technique.Environmental renovation is carried out energetically by country simultaneously, and the production equipment to petroleum industry proposes higher requirement.
Gluing core is the important component of rotation assembly, and actuating sleeve bottom connection glue core, glue core sealing drilling rod works as drill with ferrule
When bar driver drives actuating sleeve rotates, actuating sleeve just drives gluing core cup, gluing core to rotate together, and then drives whole bearing
Assembly rotates.
The gluing core of current rotation assembly is as shown in figure 1, the gluing core used both at home and abroad is all by actuating sleeve, gluing core
Seat, gluing core cup, upper gland composition, upper gland, using being threadedly coupled, are easy to occur with gluing core cup among using process
The situation that upper gland unclamps with gluing core cup screw thread, and gluing core print seat and gluing core cup sealing are poor.
The content of the invention
The purpose of this utility model is：A kind of gluing core of environmentally friendly closed rotating blowout preventer is provided, existing rotation is solved
Turn the problem of assembly is easily unclamped using upper gland among process with gluing core cup screw thread and gluing core print seat and gluing core cup is close
It is the problem of envelope property difference, simple in construction, it is safe and reliable, improve the operating efficiency of under balance pressure drilling.
Technical solution of the present utility model is：The environmentally friendly new gluing core of closed rotating blowout preventer includes driving
Set, hexagon socket head cap screw, O-ring, nut, glue core, gluing core cup and bolt, using some high between actuating sleeve and gluing core cup
The hexagon socket head cap screw connection of intensity, if being sealed between actuating sleeve and gluing core cup by the O-ring of arterial highway fluorubber material, glue
Core is by nut check in actuating sleeve bottom, and the bolt of gluing core cup bottom is used to connect other parts, is monolithically fabricated environmental protection close
The new gluing core of enclosed rotating blowout preventer.
The beneficial effects of the utility model are：Make that the gluing cored structure of rotation assembly is simple, firm and reliable connection is effectively kept away
The problems such as caused thread looseness, seal failure during the reversion of kelly bar driver drives rotation assembly is exempted from, it is ensured that sealedly
Reliability, substantially increases the service life of product, makes under balance pressure drilling work more efficiently.
Brief description of the drawings
Fig. 1 is former under balance pressure drilling gluing cored structure schematic diagram.
Fig. 2 is gluing cored structure schematic diagram of the present utility model.
In figure：1 actuating sleeve, 2 hexagon socket head cap screws, 3O type circles, 4 nuts, 5 glue cores, 6 gluing core cups, 7 bolts.
Embodiment
Technical solutions of the utility model are further illustrated below in conjunction with the accompanying drawings.
As shown in Fig. 2 the environmentally friendly new gluing core of closed rotating blowout preventer include actuating sleeve 1, it is hexagon socket head cap screw 2, O-shaped
Circle 3, nut 4, glue core 5, gluing core cup 6 and bolt 7, using interior the six of some high intensity between actuating sleeve 1 and gluing core cup 6
Corner bolt 2 is connected, if being sealed between actuating sleeve 1 and gluing core cup 6 by the O-ring 3 of arterial highway fluorubber material, glue core 5 leads to
Cross nut 4 and be locked at the bottom of actuating sleeve 1, the bolt 7 of 6 bottoms of gluing core cup is used to connect other parts, is monolithically fabricated environmental protection close
The new gluing core of enclosed rotating blowout preventer.
