It is mobile.
(2) right-hand member of the well cementation sliding sleeve is, near one end of lower contact 22, to move right i.e. near the side of lower contact 22
To movement.
It will be appreciated by persons skilled in the art that above-mentioned being limited only to is easy to describe what the embodiment of the present invention was provided
Technical scheme, and the practical structures of the non-limiting well cementation sliding sleeve.Therefore items of the well cementation sliding sleeve that the embodiment of the present invention is provided
Part can connect from left to right successively, also can connect from right to left successively.
The operation principle of the well cementation sliding sleeve that the embodiment of the present invention is provided is as described below：
By top connection 1 and lower contact 22 by the well cementation sliding sleeve together with sleeve pipe connection, and with entering horizontal well under sleeve pipe
In, now sliding sleeve 25 is placed in the left end in sliding sleeve chamber 45.Open signal, electric pipe nipple I are sent by terrestrial radio dispensing device
Receive, identification open signal drives sliding sleeve 25 to move right in sliding sleeve chamber 45 so as to control hydraulic control pipe nipple II and commutation pipe nipple III
It is dynamic so that the first pressure break hole 17 connects with the second pressure break hole 18 and the 3rd pressure break hole 19, that is, open sliding-sleeve nipple IV.Now sliding
The pressure break through hole for connecting the well cementation sliding sleeve inner chamber and the horizontal well borehole wall is defined on set pipe nipple IV.So that be passed through the well cementation sliding
Fracturing fluid in set can carry out frac treatment by pressure break through hole to the well section peripheral region.After frac treatment terminates, no longer
Fracturing fluid is passed through in well cementation sliding sleeve, and shutdown signal is sent by terrestrial radio dispensing device.Electrically pipe nipple I is received, known
Other shutdown signal drives sliding sleeve 25 to be moved to the left in sliding sleeve chamber 45 so as to control hydraulic control pipe nipple II and commutation pipe nipple III so that the
One pressure break hole 17 is staggered with the second pressure break hole 18 and the 3rd pressure break hole 19, that is, close the sliding-sleeve nipple IV.
In the well cementation sliding sleeve provided using the embodiment of the present invention, keeping at a certain distance away on same sleeve pipe, it is more to connect
The individual well cementation sliding sleeve, one removes in horizontal well, and opens different well cementation sliding sleeves realizations to shale gas well water by remote control
The multistage fracturing operation of horizontal well section.
The well cementation sliding sleeve that the embodiment of the present invention is provided is operated using radio control, and control accuracy is high, timeliness is fast, sliding sleeve
Action is accurate；Simultaneously the well cementation sliding sleeve is easy to operate, can open repeatedly, simplifies fracturing operation, realizes to shale gas etc. very
The Efficient Development of rule oil-gas reservoir.
Specifically, for the fracturing effect being further ensured that when implementing pressure break, it is uniformly arranged along the circumference of sliding sleeve 25 multiple
First pressure break hole 17, correspondingly, arranges quantity identical and along sliding sleeve outer tube 16 circumferential equally distributed the on sliding sleeve outer tube 16
Two pressure break holes 18, and the position in the second pressure break hole 18 of correspondence arranges the pressure break hole of quantity identical the 3rd on sliding sleeve inner core 23
19.Uniform pressure break of the well cementation sliding sleeve to bottom around is so ensure that, is reduced because of adjacent well section caused by the unbalance stress of stratum
The possibility of sleeve pipe deformation, raising equipment uses degree of safety.With regard to the first pressure break hole 17, the second pressure break hole 18 and the 3rd pressure break hole
19 quantity is not specifically limited, and for example it can be 2,3,4 etc..
Additionally, sliding-sleeve nipple IV directly can be connected with lower contact 22, i.e., by sliding sleeve outer tube 16 and sliding sleeve inner core 23
Right-hand member connects lower contact 22, the left end closure sliding sleeve chamber 45 of now lower contact 22.But in order to improve sliding sleeve chamber 45 sealing and
Sliding-sleeve nipple IV and the connective stability of lower contact 22, the well cementation sliding sleeve that the embodiment of the present invention is provided is in sliding-sleeve nipple IV with
Bottom end cover 21 is additionally provided between joint 22.The left end of the bottom end cover 21 is connected with sliding sleeve outer tube 16 and sliding sleeve inner core 23, and
The left side of bottom end cover 21 has blocked the right part in sliding sleeve chamber 45, enhances the sealing in sliding sleeve chamber 45, contributes to realizing hydraulic control
Pipe nipple II and commutation pipe nipple III drive the moving left and right in sliding sleeve chamber 45 of sliding sleeve 25.The right side of the bottom end cover 21 and lower contact
22 left side connects, and sliding sleeve outer tube 16 and lower contact 22 are separated so that lower contact 22 is only connected with sliding sleeve inner core 23.
So when the well cementation sliding sleeve is connected on sleeve pipe, the operation to lower contact 22 does not interfere with the main part of well cementation sliding sleeve
Point, enhance the connective stability and safety in utilization of the well cementation sliding sleeve.Further, in the bottom end cover 21 and sliding-sleeve nipple IV
Seal assembly is provided with the junction of lower contact 22, the connective stability of inter-module and the sealing effect in sliding sleeve chamber 45 is improved
Really.For bottom end cover 21 is not specifically limited with the connected mode of sliding-sleeve nipple IV and lower contact 22, can be using threaded connection, weldering
Connect, rivet.
