Abstract
The utility model provides an outer sliding sleeve type releasing tool for anti-sand process, comprising an upper joint, a lower joint, a central axis, an outer tube, the short piece of the washing pipe, a partial flow head, a partial flow seat, a steel ball, and a tripping ball plate. The upper joint is connected on the upper end of the central axis, the partial flow head is connected on the lower end of the central axis, and a releasing sliding sleeve is arranged on the exterior of the central axis. The outer tube is connected on the releasing sliding sleeve, and the lower end of the outer tube is connected with the lower joint. The partial flow seat and the short piece of the washing pipe are orderly connected on the partial flow head. The steel ball and the tripping ball plate are installed on the partial flow seat. The utility model adopts the releasing structure of the outer sliding sleeve type, and has the advantages that the sliding space is long enough, the upper and the lower dead points can be effectively controlled, and the releasing procedure can be smoothly carried out. The utility model can be used for the anti-sand technology of the sand exclusion.
Description
One, technical field
The utility model relates to the oil exploitation downhole tool, relates in particular to a kind of outer sliding sleeve sand control releasing tool.
Two, background technology
The back-off sand control releasing tool of The field all is an inner sliding sleeve formula structure at present, its shortcoming and defect is because its inner space is limited, there are not enough sliding distances, there is the dead point in the motion, therefore, is difficult to guarantee the trouble-free operation of giving up, produce difficulty in case give up, will directly influence carrying out smoothly of whole sand-preventing process and subsequent handling, cause incuring loss through delay construction period, increase the adverse consequences of cost.
Three, summary of the invention
The technical problems to be solved in the utility model provides a kind of improved outer sliding sleeve sand control releasing tool, shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art, that guarantees to give up carries out smoothly, safety, moves the sand-preventing process measure on schedule.
Outer sliding sleeve sand control releasing tool described in the utility model, comprise top connection, lower contact, axle, outer tube, washing pipe pipe nipple, shunt head, distributary base, steel ball and kick back, described axle upper end connects top connection, the lower end connects shunt head, the sliding sleeve of giving up is installed in the outside, connects outer tube on this sliding sleeve of giving up, and the outer tube lower end connects lower contact, connect distributary base and washing pipe pipe nipple on the described shunt head successively, install steel ball and kick back on the distributary base.
Wherein, the described sliding sleeve of giving up is that an end is provided with inside and outside shoulder and externally threaded tubular structure, and it is provided with shoulder in the spline grooved; Described axle is provided with the outer lug boss that matches with the interior shoulder of the spline grooved of the sliding sleeve of giving up; Be installed on movable sealing inside and outside the described sliding sleeve of giving up with its motion; Described outer tube is provided with and connects with other instrument and prevent the outer gingival cyst of mucous gland in the newborn button that it moves up; Be installed on body resistance-strengthening tablets in the described lower contact.
The utility model compared with prior art has following advantage:
1, adopts the outer sliding sleeve formula structure of giving up, have sufficiently long sliding space, can effectively control bottom dead centre, make that the operation of giving up is smooth and easy carries out.
2, adopt movable sealing, improve the bearing pressure of instrument.
3, the gingival cyst of mucous gland in the newborn button that is provided with on the outer tube has been created the condition that connects with other instrument and has been improved safety of the present utility model and reliability.
