The upper end of the central tube is connected with the upper joint; the blocking seat is arranged in the middle of the central tube; the piston is arranged below the blocking seat; the inner tube, the lower seal sleeve, the bearing sleeve and the lower joint are arranged and connected in sequence outside the central tube; the pressure cap is arranged outside the upper end of the inner tube; the seal sleeve, the leather cup, the shrink sleeve and the outer slide sleeve are arranged in sequence below the pressure cap; the seal and the spacer are arranged below the pressure cap, on the seal sleeve and in the leather cup; the inner slide sleeves are respectively arranged below the lower seal sleeve, on the lower joint and inside the shrink sleeve and the outer slide sleeve. The utility model adopts the leather cup to protect a release device and has the characteristics of eroding resistance and good seal. The utility model is mainly applied in the technical tool of an oil exploitation horizontal well.
Description
One, technical field
The utility model relates to a kind of oil exploitation downhole tool, relates in particular under a kind of horizontal well towards packer.
Two, background technology
At present, the conventional packer of field use exists following shortcoming or deficiency: 1. in the process of sand washing, set very easily midway; 2. poorly sealed in the fluid cylinder, Yi Jinsha; 3. impact resistance is poor, can't realize the operation that washes down of horizontal well sand control pipe; 4. some quicksand oil reservoirs, sand washing can not rinse the surplus sand of horizontal segment fully.
Three, summary of the invention
The purpose of this utility model provides under a kind of improved horizontal well towards packer, has both overcome the shortcoming or the deficiency that exist in the above-mentioned prior art effectively, solves the problem that horizontal well limit bottom dashes again effectively.
Towards packer, comprise top connection, pressure cap, interior pipe, gland, sealing shroud, spacer, leather cup, contraction cover, lower sleeve gasket, inner sliding sleeve, outer sliding sleeve, block seat, single current ball, pressure-bearing cover, central tube, piston, lower contact, lock dog and the pin of giving up under the horizontal well described in the utility model.The central tube upper end is connected with top connection, in the middle part seat of blocking is installed, under this seat of blocking piston is installed, central tube is installed in turn outward and is connected with interior pipe, lower sleeve gasket, pressure-bearing cover and lower contact, the outer pressure cap that is equipped with in pipe upper end in described, gland, leather cup, contraction cover and outer sliding sleeve are installed under this pressure cap in turn, under the described pressure cap, on the sealing shroud, interior pipe is outer and leather cup in sealing shroud and spacer are installed in turn, under the described lower sleeve gasket, in the lower contact, in contraction cover and the outer sliding sleeve inner sliding sleeve is installed.
Wherein, described piston is located with lower contact and central tube respectively with the pin of giving up mutually by lock dog.Described lower contact is provided with inner convex platform, and this inner convex platform is provided with locked groove, and described lock dog matches with it.Described central tube is provided with boss, and looping space between interior pipe and the pressure-bearing cover.Described central tube is provided with and narrates the flowing hole that annular space is connected.
The utility model compared with prior art has the following advantages:
But 1, adopt leather cup to shrink protection releasing device, good seal, anti-washing away towards packer under the horizontal well;
2, ball seat adopts the bicone design, has not only guaranteed fall position but also guarantee can carry out the operation that washes down of horizontal well sand control pipe again by sealing effectiveness of spheroid.
