Abstract
The utility model relates to the technical field of continuous cycle drilling, in particular to an inner inserting-pulling connecting tool on a pipe wall. The tool comprises an inserting-pulling parent body and an inserting-pulling connector. The inserting-pulling parent body is designed on the hollow pipe wall. The inserting-pulling parent body comprises a connecting face and a ball groove. The inserting-pulling connector comprises lock balls, a sealing ring, a ball sleeve and an inserting-pulling sleeve. The ball sleeve is in a cylindrical pipe shape. Ten ball holes with incomplete circumference are formed in the end portion of the ball sleeve. The ball holes contract from inside to outside. The ball-shaped lock balls arranged from the inner side of the ball sleeve and then are distributed along the circumference direction. The lock balls can roll inside the ball holes in a limiting mode. The ball sleeve with the lock balls and the inserting-pulling sleeve are arranged outside an inner sleeve. A locating key groove is machined on the inserting-pulling sleeve. The key groove enables the inserting-pulling sleeve to be capable of moving axially. The inner sleeve, the inserting-pulling sleeve and the ball sleeve are limited in a locating mode through a locating key. According to the inner inserting-pulling connecting tool on the pipe wall, quick connection between a pipe wall upper side hole and the connecting tool is achieved, and safety and reliability of connecting and sealing are guaranteed.
Description
Technical field:
The utility model relates to a kind of continuous cyclic drilling technical field, particularly the interior plug fastening means on a kind of tube wall.
Background technology:
When oil drilling, implement not termination of pumping continuous cyclic drilling technology, can reduce down-hole pressure fluctuation when making a trip and making up a joint, reduce the generation of down-hole accident and complex situations.The continuous cyclic drilling technology is by continuous circulation pipe nipple and supporting interpolation type quick connection tool and supporting technology realization.Connect in advance two-position three way continuous circulation pipe nipple in the upper end of column to be accessed during execute-in-place, this pipe nipple can be realized vertical run and the interchannel conversion of side mouth, before connecing column, the side mouth pipeline that need will be connected with drilling fluid pump is connected to the side mouth position of two-position three way continuous circulation valve pipe nipple fast, and guarantee that this connection is safe and reliable, for the side cause for gossip with two-position three way continuous circulation pipe nipple now fast and safely is connected, need the interpolation type fastening means on a kind of tube wall of design, guarantee effective enforcement of continuous cyclic drilling technology.
The utility model content:
The technical problems to be solved in the utility model provides the interior plug fastening means on a kind of tube wall, and this instrument has been realized quick connection the between tube wall upper-side hole and fastening means, and it is reliable to guarantee to connect sealingly secure.Overcome existing not termination of pumping continuous cyclic drilling operation and lacked a kind of deficiency that realizes the instrument that fast and safely is connected between tube wall upper-side hole and fastening means.
Technical solution adopted in the utility model is: the interior plug fastening means on a kind of tube wall is comprised of plug parent and plug joint; The design of plug parent is on the tube wall of hollow, and the plug parent comprises joint face and pearl groove; The plug joint comprises the lock pearl, sealing ring, pearl cover and plug cover, the pearl cover is cylindrical tube, the end is furnished with ten circumferential imperfect hole of beads, from inside to outside narrow in the hole of bead, the ball catch pearl is from the pearl cover installed inside Later Zhou Dynasty, one of the Five Dynasties to distribution, in the hole of bead, can limitedly roll, the outside that is installed in inner sleeve is overlapped in pearl cover and plug with the lock pearl, plug puts and is processed with the positioning key keyway, and keyway makes the plug cover can move axially inner sleeve, pass through the positioning key positioning limit between plug cover and the pearl cover, overcoat is connected with the pearl cover by screw thread, between plug cover and the inner sleeve back-moving spring is installed, adapter sleeve is threaded connection interior and puts, and seals by sealing ring.
The beneficial effects of the utility model are: the utility model is owing to adopted the plug parent and plugged the mode that joint matches, thereby has a quick function that is connected that realizes between tube wall upper-side hole and fastening means, and it is reliable to guarantee to connect sealingly secure, after finishing using, the tube wall upper-side hole can be removed fast with fastening means and be connected.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in drawings, the interior plug fastening means on a kind of tube wall is comprised of plug parent and plug joint; The design of plug parent is on the tube wall of hollow, and the plug parent comprises joint face 10 and pearl groove 11; The plug joint comprises lock pearl 1, sealing ring 2, pearl cover 3 and plug cover 6, pearl cover 3 is cylindrical tube, the end is furnished with ten circumferential imperfect hole of beads, from inside to outside narrow in the hole of bead, ball catch pearl 1 is overlapped the 3 installed inside Later Zhou Dynasty, one of the Five Dynasties to distribution from pearl, in the hole of bead, can limitedly roll, be installed in the outside of inner sleeve 8 with the pearl cover 3 of locking pearl 1 and plug cover 6, be processed with the positioning key keyway on the plug cover 6, keyway can move axially plug cover 6, inner sleeve 8, pass through positioning key 4 positioning limit between plug cover 6 and the pearl cover 3, overcoat 5 is connected with pearl cover 3 by screw thread, between plug cover 6 and the inner sleeve 8 back-moving spring 7 is installed, adapter sleeve 9 is threaded connection on inner sleeve 8, and seals by sealing ring.
Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
