Detailed description of the invention
This detailed description of the invention provides a kind of sleeve butt-buckling device, and it can solve and cause because treating to there is shelter above tie-back casing the problem that construction is failed.And in a preferred approach, can also solve because reservoir sand is many, the problem of suppressing pump caused, and easily there is poorly sealed problem after sleeve pipe make-up.
Please refer to Fig. 2-Fig. 4, the sleeve butt-buckling device that this detailed description of the invention provides comprises casing coupling 1, centralizer body 3 and dials hook guide shoe 4, and three is hollow tubular structures.Wherein, casing coupling 1 is for connecting the sleeve pipe waiting to send into down-hole, and one end of centralizer body 3 is fixedly connected with casing coupling 1, and the other end of centralizer body 3 is fixedly connected with group hook guide shoe 4.Particularly, three can be fixedly connected with in the following way, and casing coupling 1 bottom is inserted centralizer body 3 top inner via hole and welded, and centralizer body 3 bottom is inserted and dialled latus rectum in hook guide shoe 4 top and weld.Certainly, be also fixedly connected with by alternate manner, such as, pin joint, clamping etc.
It should be noted that, in this detailed description of the invention, by dial hook guide shoe 4 bottom arrange in order to snail hook shape structure.Setting like this, during as there being shelter on tie-back casing, be spiral hook formation owing to dialling hook guide shoe 4 bottom, this kind of structure can push shelter aside, to expose sleeve pipe top of fish, sleeve pipe top of fish is entered smoothly and dials in hook guide shoe 4, then buckled tightly by sleeve pipe.
In the preferred version that this detailed description of the invention provides, the lateral wall dialling hook guide shoe 4 is provided with axially extended groove structure.The quantity of groove can arrange many, and such as, can be specially 2 or 3 or 4 etc., its concrete quantity specifically can set according to actual conditions, does not do concrete restriction herein.And multiple groove can be evenly distributed on the outer peripheral face of group hook guide shoe 4.Setting like this, go into the well after sleeve pipe is connected make-up time, if having sand setting outside sleeve pipe, have axially extended groove owing to dialling on hook guide shoe 4, groove plays channeling, there will not be and suppresses pump phenomenon.
In the another kind of preferred version of this detailed description of the invention, the inwall of casing coupling 1 is removably provided with sealing ring 2.The quantity of sealing ring 2 can be specially 2, certainly, also can be other quantity, and such as 3,4,1 etc., its concrete quantity specifically can set according to actual conditions, does not do concrete restriction herein.Setting like this, when sleeve pipe make-up, sealing ring 2 can be fixed on sleeve pipe to buckle, improve make-up connect sealing.
In addition, two pin thread pipe nipple 5 can also be provided with in casing coupling 1, be buckled at casing coupling 1 internal thread by screwed connection, situation when being box cupling for use in parts casing pipe under make-up.
The sleeve butt-buckling device that this detailed description of the invention provides, in the construction of workover treatment change casing, first damaged sleeve pipe in well is taken out, again according to the button-type of down-hole casing top of fish, select the sleeve butt-buckling device of suitable type to carry out make-up, if the button-type pin thread of down-hole casing top of fish, select the instrument shown in Fig. 2, if the button-type of down-hole casing top of fish is box, select the instrument shown in Fig. 3.
G.I.H after this detailed description of the invention is connected with sleeve pipe, during down to 1m above apart from top of fish, record suspending weight, turn on pump rinses top of fish, slowly transfer casing string, gently slow-speed is pressed to the expectation make-up degree of depth, if have sand setting outside sleeve pipe, longitudinal groove is had owing to dialling on hook guide shoe 4, there will not be and suppress pump phenomenon, push aside to expose sleeve pipe top of fish by the hook of dialling dialled on hook guide shoe 4 as having on tie-back casing during shelter, sleeve pipe top of fish is entered smoothly and dials in hook guide shoe 4, termination of pumping, transferring sleeve pipe makes the screw thread of top of fish enter in centralizer body 3, under the centralizing function of centralizer body 3, slow-speed is drawn button and is made make-up device and down-hole casing realize being connected, then will buckle tightly with rotating disk, sealing ring 2 Sealed casing pipe is to buckle, improve the sealing that make-up connects, complete sleeve pipe make-up tieback.
