Abstract
The utility model relates to a layering release combination packer device. The layering release combination packer device comprises an oil well pump anchor, a balance piston packer, a pressure communication valve, a bidirectional plugging self-sealing setting ball seat and a pressure drop throttler, the layering release combination packer device can be used in a multi-stage mode, and 3-5 oil layers can be used in series simultaneously. An oil well pump is anchored through the oil well pump anchor and is anchored in a coaxial and bidirectional mode to avoid stroke loss of the oil well pump, and oil pipes are prevented from moving; the packer is of a balance piston design structure; and the bidirectional plugging self-sealing setting ball seat achieves forward and backward bidirectional plugging of the packer. The layering release combination packer device can achieve layering release, is free of new operation, replacement of the packer, and stopping of a well, and meanwhile, reduces environmental pollution caused by operation.
Description
Technical field
The utility model belongs to the oilfield production technical field, relates to a kind of layering and discharges the combination packer device.
Background technology
Packer is the important downhole tool during oilfield is produced, but existing packer is single-unit, can only oil reservoir of shutoff.In actual production, oil reservoir often multilayer is fuel-displaced, and it is fuel-displaced directly to affect other oil reservoir behind single the layer water breakthrough, just need to stop well in the production, again operation proposes existing working string, changes packer, this replacing downhole tool is that a very large cost drops into, the work production expense is increased, cause simultaneously oil well to stop production, impact is produced, reduce oil production, also can bring serious environment pollution in the operation process.
Summary of the invention
The purpose of this utility model is to overcome shortcomings and deficiencies of the prior art, provides a kind of layering to discharge the combination packer device.
Layering described in the utility model discharges the combination packer device, comprises oil well pump anchor, dummy piston packer, pressure intercommunicating valve, two-way shutoff self-sealing setting ball seat, pressure drop restriction choke, multistage use, the use of connecting simultaneously of 3-5 oil reservoir.Utilize oil well pump anchor grappling oil well pump, coaxially bidirectionally anchoring is avoided the oil well pump loss of plunger stroke, avoids the oil pipe play; Packer adopts the dummy piston project organization; Two-way shutoff self-sealing setting ball seat is realized positive and negative two-way plugging packer.
By in advance designing requirement with the tubing string for preparing down to projected depth, when treating that tubing pressure is the 10MPa left and right sides, voltage stabilizing 15min, after no longer changing, pressure stability is pressurized to about 20MPa, realize the sealing of oil pipe and casing annulus, reach the layering purpose, open the pressure drop restriction choke this moment.During workover treatment, reduce lifting load and realize that layering discharges, and guarantees device security.
The utlity model has good beneficial effect, the use of connecting simultaneously of 3-5 oil reservoir, layering discharges, need not be from new operation, need not change packer, need not stop well, reduce simultaneously the environment pollution that operation brings.

The specific embodiment
Layering discharges the combination packer device as shown in the figure, comprises oil well pump anchor 1, dummy piston packer 2, and pressure intercommunicating valve 3, two-way shutoff self-sealing setting ball seat 4,5, three oil reservoir series connection of pressure drop restriction choke are used.Pass through oil well pump anchor 1, dummy piston packer 2 between per two oil reservoirs, pressure intercommunicating valve 3, two-way shutoff self-sealing setting ball seat 4, pressure drop restriction choke 5 are separated, utilize oil well pump anchor 1 grappling oil well pump, coaxially bidirectionally anchoring is avoided the oil well pump loss of plunger stroke, avoids the oil pipe play; Packer adopts the dummy piston project organization; Two-way shutoff self-sealing setting ball seat 4 is realized positive and negative two-way plugging packer.
