At present, the sliding sleeve purposes of using in the oil field operation mainly is water detection, water blockoff, controls by the mode that cable is lowered to.Patent 98235710.9 has been introduced the sliding bush apparatus of a kind of oil well water detection, water blockoff.All designed spring detent in the sliding sleeve top of this device and the lower limit body, after being lowered to corresponding interval with downhole tool is supporting, with cable on-off controller is lowered to, on ground on-off controller is powered, strut the butt joint pawl of on-off controller, make it to match with sliding sleeve upper end spring detent, portable cable is gone up in the power supply back, sliding sleeve is up, and derailing switch is opened, and tubing and casing is communicated with; The butt joint pawl of on-off controller shunk and transfer, strut the butt joint pawl, make it with the lower limit body on spring detent match, last portable cable, sliding sleeve is descending, derailing switch cuts out, the corresponding interval of shutoff.Patent 94204743.5 has been introduced a kind of rod-pumped well sleeve type water detection water blockoff connection and has been made device, and this device is made up of sliding sleeve water blockoff device and switch instrument.Sliding sleeve water blockoff device places the down-hole, and the switch instrument is ground control motor switch instrument.Adopt the switch instrument cable to be lowered to the mode of switch instrument and kit during operation, open and close sliding sleeve water blockoff device, realize the water blockoff function by the mode that raises and decentralizes.
Above-mentioned dual mode all needs to stop the oil well ordinary production, and adopts the mode that is lowered to cable, has increased the activity duration, and only has been used for water detection and water blockoff.
The utility model content
The purpose of this utility model is: a kind of interlayer control valve that is used for completion is provided, to the flow regime that changes downhole fluid under the situation that does not stop to produce, accurately controls flowing of downhole fluid.
The technical solution adopted in the utility model is: be used for the interlayer control valve of completion, mainly be made up of top connection, last overcoat, inner sliding sleeve, following overcoat and lower contact.Top connection has centre bore, and there is external screw thread at the top connection two ends, it is characterized in that: be connected with overcoat on the external screw thread of top connection lower end.Be connected with following overcoat at the lower end of last overcoat screw thread, be connected with lower contact at the lower end screw thread that descends overcoat.Top connection can link to each other with oil pipe with lower contact, and the interlayer control valve that will be used for completion is connected the down-hole and keeps a grip on.On the inwall of last overcoat and following overcoat an inner sliding sleeve is arranged, inner sliding sleeve has centre bore for the cylinder bodily form, on the outer wall of inner sliding sleeve annular piston is arranged, and the annular piston of inner sliding sleeve is in the annular groove of last outer casing inner wall.Hydraulic channel on the upper end of last overcoat has, last hydraulic channel UNICOM inner sliding sleeve annular piston upper space, last hydraulic channel feed liquor can promote annular piston and move down; In the upper end of last overcoat following hydraulic channel is arranged, following hydraulic channel UNICOM inner sliding sleeve annular piston lower space, following hydraulic channel feed liquor can promote annular piston and move up.Stream with uniform distribution road on the wall of following overcoat.When inner sliding sleeve during, can stop up the runner on the overcoat wall down to lower slider.
After making the inner sliding sleeve downslide arrive the precalculated position, stop it free movable in inner chamber, play certain sealing function simultaneously, outside down, put the damping rubber circle, the position of damping rubber circle is in the cannelure on following outer casing inner wall top.
In order to improve the sealing performance at inner sliding sleeve two ends, on the inwall of last overcoat and following overcoat, sealing ring is arranged respectively.
In order to improve the sealing of inner sliding sleeve annular piston, on inner sliding sleeve annular piston outer wall, sealing ring is arranged.
For in hydraulic failure, when inner sliding sleeve can not slide, the employing instrument directly promotes the inner sliding sleeve motion in oil pipe, in the top and bottom of inner sliding sleeve inwall a groove is arranged respectively.
Be connected by two 15 millimeters the hydraulic line that is lowered between the tubing and casing annular space between down-hole interlayer control valve in the utility model and the ground, suppress the duty of interlayer control valve under the control well by ground, thereby can be under the situation that does not stop to produce the casing programme reprovision, accurately the control downhole fluid is mobile, thereby has saved the activity duration.Interlayer control valve master among the present invention is used for the separate zone production of oil well and closes and adopt, and can be used for the oil reservoir water blockoff
The beneficial effects of the utility model: the utility model is used for the interlayer control valve of completion, can suppress the action of driving sliding sleeve by hydraulic line on ground, under the situation that does not stop to produce, change the down-hole flow regime, thereby reach the purpose that multiple zone is produced under the control well.And have processing, an advantage easy for installation.
