Technical field
The utility model relates to sliding sleeve switch instrument, relates in particular to a kind of sliding sleeve switch instrument of the fluid pressure type for oil extraction in oil field.Belong to Offshore Engineering field.
Background technology
At present, the sliding sleeve switch instrument using on existing oil field, generally need to adopt steel wire operation to carry out action control to sliding sleeve; Due to used sliding sleeve switch instrument can not be selectively to certain sliding sleeve action, therefore, move certain sliding sleeve, be located at these all sliding sleeves more than sliding sleeve and be also difficult to the unwanted action of generation of avoiding; So, in the time that there is multiple sliding sleeve down-hole, the perseveration of sliding sleeve is also just increased, so, not only strengthen workload; And, in high angle hole and horizontal well, be difficult to remove switching sliding sleeve with steel wire operation.
Utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of sliding sleeve switch instrument of fluid pressure type, it utilizes the mode of hydraulic pressure to control the action of sliding sleeve switch instrument, thereby, can selectively object sliding sleeve be opened or be closed, the problem of effectively having avoided mechanical type sliding sleeve switch to exist; Not only improve operating efficiency, and, coordinate coiled tubing to be applied to horizontal well, manipulate the sliding sleeve of horizontal well, solve the problem of horizontal well sliding sleeve switch.
The purpose of this utility model is realized by following technical scheme:
A sliding sleeve switch instrument for fluid pressure type, is characterized in that: comprising: the inside of a central tube, this central tube is provided with a feed pathway, and central tube outside is provided with several shoulders, and central tube end is connected with a lower contact; Wherein, be set with a spring base on central tube, spring base is enclosed within on central tube after being connected with a baffle ring; One upper pressing cap, operation block, lower pressing cap are installed between spring base and baffle ring successively, and radial spring is also installed between spring base and operation block, the top of piston contacts with operation block, the bottom of piston is connected with lower contact, one sealing drum is installed in piston, an axle spring is installed between piston and lower contact.
The feed pathway of described central tube is linked up mutually with the feed pathway of sealing drum.
Described sealing drum is positioned a shoulder place of central tube.
Described operation block is to be made up of the identical fritter of several structures, and uniform along center line, on each fritter, is equipped with circular groove.
Described spring base is provided with circular groove, and this circular groove is corresponding with the circular groove of operation block, and radial spring is arranged between circular groove.
Between described central tube and lower contact, sealing drum and central tube, between sealing drum and piston, be equipped with the sealing of O RunddichtringO.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, it utilizes the mode of hydraulic pressure to control the action of sliding sleeve switch instrument, and when well head is suppressed, liquid flows from inlet opening enters, the operation block of sliding sleeve switch instrument is stretched out, and can move to target sliding sleeve; After release, the operation block of sliding sleeve switch instrument is retracted, and can not produce action to any sliding sleeve, only need move to target sliding sleeve; Reduce the switch motion unnecessary to other sliding sleeve, workload and operating risk, and, coordinate with coiled tubing, can be applied to horizontal well, solve the problem of horizontal well sliding sleeve switch, there is larger practical value.
