Abstract
Provided is an ocean oil well hydraulic sliding sleeve device. The ocean oil well hydraulic sliding sleeve device comprises an upper joint, a liquid control pipeline, a liquid control pipeline joint, a piston, a hydraulic cylinder, a sliding sleeve, a spring, a body and a lower joint, wherein the upper joint is sequentially connected with the hydraulic cylinder, the body and the lower joint, the sliding sleeve, the spring are sequentially arranged in the body above the lower joint and below the hydraulic cylinder, the piston is arranged inside the hydraulic cylinder, and the liquid control pipeline and the liquid control pipeline joint are arranged on the upper joint. The ocean oil well hydraulic sliding sleeve device has the advantages of being capable of carrying out process measures such as well killing, chemical agent filling and workover treatment under the condition of not moving a pipe column and is convenient and quick; oil jacket intercommunication process can be carried out on ground and is simple, safe and quick; and opening and closing are reliable and opening and closing operation can be carried out repeatedly, and additional pipe column running is not needed. In addition, the ocean oil well hydraulic sliding sleeve device has the advantages of being short in operation period and low in cost and the like, and is mainly applied to ocean oil operation and production process.
Description
Technical field
The utility model relates to the oil exploitation downhole tool, particularly a kind of ocean oil well hydraulic sliding sleeve device.
Background technology
Existing oil well sliding bush apparatus, be generally mechanical type sliding sleeve or high-voltage switch gear formula structure, be installed on the darker position of down-hole string, for the oil field well switch contributes strength, but it exists following shortcoming or deficiency simultaneously: 1. mechanical type sliding sleeve switch must with special opening-closing tool under the winch wire band, open or close sliding sleeve, the aboveground operation of trivial operations, particularly marine oil is more numerous and diverse; 2. need be more with manpower and materials; 3. long construction period, cost is high; When 4. high-voltage switch gear uses, pressurize in oil pipe, discharge this switch, but it just can not close after opening, produce, must trip out tubing string and change, the number of times that this has just increased a lower tubular column has prolonged construction period, has improved cost of production.
Summary of the invention
The purpose of this utility model provides a kind of improved ocean oil well hydraulic sliding sleeve device, and shortcoming or deficiency that it can effectively overcome and avoid existing in the above-mentioned prior art have reduced the number of times of lower tubular column, shorten construction period, reduce production costs.
Ocean described in the utility model oil well hydraulic sliding sleeve device comprises top connection, liquid controling pipe line, liquid controling pipe line joint, piston, fluid cylinder, sliding sleeve, spring, body, lower contact.Described top connection is connected with fluid cylinder, body, lower contact in turn, and sliding sleeve, spring are installed in the body in the lower contact, under the fluid cylinder in turn, and piston is installed in the fluid cylinder, and liquid controling pipe line, liquid controling pipe line joint are installed in the top connection.
Wherein, on the described top connection middle wall liquid controling pipe line is installed, is connected with the liquid controling pipe line joint on this liquid controling pipe line.Described liquid controling pipe line is connected with liquid controling pipe line joint, fluid cylinder 5.Described sliding sleeve, body are provided with the corresponding mutually circulation passage of UNICOM.
The utility model has following advantage compared with prior art:
1, for the airtight producing well of oil jacket annular space provides a kind of connectivitv tool, fixed tubular column can carry out the technological measures such as kill-job, chemical injection, workover treatment, and is convenient and swift;
2, oil jacket connection operation is carried out on ground, and is easy, safe, quick;
3, switch is reliable, but the repeat switch operation must not play lower tubular column separately, and duty cycle is short, and cost is low.
Description of drawings
Fig. 1 is a kind of example structure schematic diagram of the present utility model.
The specific embodiment
Referring to Fig. 1, a kind of ocean oil well hydraulic sliding sleeve device comprises top connection 1, liquid controling pipe line 2, liquid controling pipe line joint 3, piston 4, fluid cylinder 5, sliding sleeve 6, spring 7, body 8, lower contact 9.Top connection 1 is connected with fluid cylinder 5, body 8, lower contact 9 in turn, and sliding sleeve 6, spring 7 are installed in the body 8 in the lower contact 9, under the fluid cylinder 5 in turn, and piston 4 is installed in the fluid cylinder 5, and liquid controling pipe line 2, liquid controling pipe line joint 3 are installed in the top connection 1.
On top connection 1 middle wall liquid controling pipe line 2 is installed, is connected with liquid controling pipe line joint 3 on this liquid controling pipe line 2.Liquid controling pipe line 2 is connected with liquid controling pipe line joint 3, fluid cylinder 5.Sliding sleeve 6, body 8 are provided with the corresponding mutually circulation passage of UNICOM.
During use, the utility model is by liquid controling pipe line 2 controls that are attached to oil-pipe external wall.When needs carry out oil jacket connection operation, to suppress by liquid controling pipe line 2 ground, pushing piston 4 and sliding sleeve 6 are descending, after sealing ring group on the sliding sleeve 6 moved past the through hole of body 8, interior accessibke porosity was corresponding, formed the oil jacket passage, keep hydraulic pressure, then this instrument is in open mode all the time; In the time of need to closing this passage, liquid controling pipe line 2 pressure releases, sliding sleeve 6 resets under spring 7 effects, and the sealing ring group separates the through hole of sliding sleeve 6 with body 8, external seal in forming, then this instrument recovers closed condition.But the utility model on flow string multiple switching, reuse the tubing string sealing after the not impact measure.
