Abstract
A bottom part filling server comprises a sealing main body, sealing plugs, a sealer, a lengthened body, a sliding sleeve, a spring cylinder, a balance hole, a spring, a lower joint and a sealing element, and is characterized in that the lower end of the sealing main body is connected with the lengthened body, the spring cylinder and the lower joint in sequence; the sealer is mounted inside the sealing main body; the spring is arranged inside the spring cylinder and seated at the upper end of the lower joint; the sliding sleeve is arranged inside the spring cylinder and seated on the spring; and the sealing plugs are mounted inside the inner cavities of the sealing main body, the sealer and the sliding sleeve. The sliding sleeve switch structure provided by the utility model has the characteristics of convenient application, reliable sealing, extrusion circulation filling and well washing, and can be widely applied to the stratum sand control process tools for a petroleum open hole horizontal well, or a perforation horizontal well, or an inclined well, or a vertical well.
Description
One, technical field
The utility model relates to the oil exploitation sand preventing tool, a kind of bottom filling server that particularly matches with sand preventing tool.
Two, background technology
In the process for petroleum recovery, to stratum operation extruding (circulation) filling anti-sand of open-hole horizontal well, perforated horizontal wells, inclined shaft, straight well, for slurry and the underground work of acidifying dish the time, owing to lack reliable supporting packing tool, thereby sand setting, obstruction, card pipe, sand control pipe usually take place all incidents such as do not go out, have a strong impact on the progress of sand control engineering, sometimes also can cause the failure of sand-preventing process, increase and drop into, increase cost.
Three, summary of the invention
The new purpose of this practicality provides a kind of supporting bottom filling server, adopts sliding sleeve, sealing plug structure, and the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art reach safety, matching operation purpose.
Bottom filling server described in the utility model, comprise sealed body, sealing plug, sealer, extended body, sliding sleeve, spring strut, balance pipe, spring, lower contact and seal it is characterized in that described sealed body lower end in turn with extended body, spring strut is connected with lower contact, described sealer is installed in the sealed body, described spring is installed in spring strut, seat is in the lower contact upper end, sliding sleeve is installed in spring strut, seat is on spring, and sealing plug is installed on sealed body, sealer and sliding sleeve inner chamber.
Wherein, described sealer comprise the following pressure ring installed successively in the gland that is connected with the sealed body lower end and this gland top, down V-type circle, middle pressure ring, go up V-type circle and upper press ring.Described sealed body bottom is provided with internal thread, is meshed with the external screw thread of gland.Described spring strut top is provided with flow passage, and the bottom is provided with balance pipe.Screen pack and adjustable ring are installed in the described balance pipe.Described sealing plug upper and lower, extended body top, sliding sleeve upper and lower part are equipped with seal.Described sealing plug top is provided with the outer step that matches with shoulder in the sealed body top, and the bottom is provided with the outer step that matches with the sliding sleeve upper end.
Advantages such as the utility model compared with prior art has matching, good reliability, is widely used, rational in infrastructure simple, and sealing is reliable, and is supporting, easy to use.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the present utility model
Five, the specific embodiment
Consult accompanying drawing, a kind of bottom filling server comprises sealed body 1, sealing plug 3, sealer, extended body 10, sliding sleeve 11, spring strut 12, balance pipe, spring 15, lower contact 16 and seal 2.Sealed body 1 lower end in turn with extended body 10, spring strut 12 is connected with lower contact 16; Sealer is installed in the sealed body 1, and spring 15 is installed in spring strut 12, and seat is in lower contact 16 upper ends, and sliding sleeve 11 is installed in spring strut 12, and seat is on spring 15, and sealing plug 3 is installed on sealed body 1, sealer and sliding sleeve 11 inner chambers.
Sealer comprise the following pressure ring 8 installed successively in the gland 9 that is connected with sealed body 1 lower end and this gland top, down V-type circle 7, middle pressure ring 6, go up V-type circle 5 and upper press ring 4.Sealed body 1 bottom is provided with internal thread, is meshed with the external screw thread of gland 9.Spring strut 12 tops are provided with flow passage, and the bottom is provided with balance pipe.Screen pack 13 and adjustable ring 14 are installed in the balance pipe.Sealing plug 3 upper and lowers, extended body top, sliding sleeve upper and lower part are equipped with seal 2.Sealing plug 3 tops are provided with the outer step that matches with shoulder in sealed body 1 top, and the bottom is provided with the outer step that matches with sliding sleeve 11 upper ends.
During use, sealed body 1 is connected in the sand control pipe end, when being lowered to the precalculated position, sealing plug 3 is lowered in the sealed body 1, when not going extremely down, pipe box is pushed away for 11 times, open spring strut 12, set up sealing sand control passage with tubing string.Add the sandfilling sand control, after stowing pressure reaches definite value, on watch out for sandpipe post 1.5m, sliding sleeve 11 is just closed the sand control passage automatically under the effect of spring 15, anti-flushing well at this moment when well head loses sand, plays sand control pipe to ground getting final product.
