Abstract
The utility model relates to a perforation seperated layer water injection integration tubular column belongs to oil field exploitation technical field. By oil pipe, go up water injection mandrel, packer, down water injection mandrel, ball seat, perforation rifle constitutes, oil pipe, go up water injection mandrel, packer, water injection mandrel, ball seat, perforation rifle threaded connection in proper order down, the packer is located between water injection mandrel, the lower water injection mandrel. The beneficial effects of the utility model are that through the combination that utilizes water injection mandrel, packer and perforation rifle, solve the loaded down with trivial details problem of well workover in -process process, can realize once accomplishing perforation, water injection process, convenient operation improves the efficiency of construction, practices thrift the operating cost.
Description
Technical field
The utility model relates to perforation seperated layer water injection integrated pipe column, belongs to oilfield exploitation technical field.
Background technology
Seperated layer water injection is a kind of important way of oil-field flooding, is the Main Means improving injection-production relation.At present, well dispensing normally first descends entrance aperture tubing string, trips out perforation tubular column after perforation, then under enter water injection string, need three times tubing strings to complete dispensing.If overflow is large in well after perforation, also needs to increase kill-job operation, just can complete water injection string.So not only increase the labour intensity of operating worker, and add operating cost.
Patent No. CN201320004996 discloses a kind of separate layer water injection string.Comprise oil pipe, at least two packers, at least two injection well downhole flow regulators, ball seat and device for plug of sieve tubes.Wherein, packer is identical with the quantity of injection well downhole flow regulator, and fewer than the quantity of oil reservoir one, oil reservoir is at least 3 layers.By the improvement of structure, effectively improve to survey and adjust efficiency, save pulling cost.But cannot perforation be realized, seperated layer water injection is once constructed.
Summary of the invention
The purpose of this utility model is to overcome the defect that in above-mentioned prior art, operation is loaded down with trivial details, provides a kind of perforation, water injection integral pipe column, realizes the object of fast hierarchical water filling after water injection well perforation.
The utility model is made up of oil pipe, upper injection well downhole flow regulator, packer, lower injection well downhole flow regulator, ball seat, perforating gun, and oil pipe, upper injection well downhole flow regulator, packer, lower injection well downhole flow regulator, ball seat, perforating gun are threaded successively, and packer is between upper injection well downhole flow regulator, lower injection well downhole flow regulator.
The beneficial effects of the utility model are the combinations by utilizing injection well downhole flow regulator, packer and perforating gun, solve the problem that in well workover process, operation is loaded down with trivial details, can realize once completing perforation, water filling operation, easy to operate, improve efficiency of construction, save operating cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
As shown in Figure 1, the utility model the utility model is made up of oil pipe 1, upper injection well downhole flow regulator 2a, packer 3, lower injection well downhole flow regulator 2b, ball seat 6, perforating gun 7, oil pipe 1, upper injection well downhole flow regulator 2a, packer 3, lower injection well downhole flow regulator 2b, ball seat 6, perforating gun 7 are threaded successively, on the tubing string of packer 3 between upper injection well downhole flow regulator 2a and lower injection well downhole flow regulator 2b.
Be serially connected with damper 4 between described packer 3 and perforating gun 7, tubing string that perforation causes can be eliminated axially or radial vibrations, avoid damaging packer 3.
Described packer 3 model is Y221, with upper injection well downhole flow regulator 2a, lower injection well downhole flow regulator 2b with the use of, can seperated layer water injection be realized.
To sleeve pipe drifting, after scraping, lower entrance aperture water injection integral pipe column, magnetic orientation school packer 3 and perforating gun 7 degree of depth qualified after, upper lifting pipe post 1.6m, rotate forward with hydraulic tongs, lower drain line 1 makes packer 3 setting, setting spatial load forecasting is at 8-12t, suppress with cementing truck and ignite perforating gun 7, drop on valve ball 5 to ball seat 6, the interface channel of sealing perforating gun 7 and ball seat more than 6 tubing string, injection well downhole flow regulator 2a in pulling, the blanking plug of lower injection well downhole flow regulator 2b, upper injection well downhole flow regulator 2a, lower injection well downhole flow regulator 2b is respectively to the stratum water filling of correspondence, one-trip string can realize perforation, the object of seperated layer water injection.
