Abstract
The utility model discloses a cannula hollow integrated separated-zone water injection process adopting tubular pile. The tubular pile comprises a cannula, an oil pipe, and a testing water distributor, a one-way constant-pressure well cleansing valve and a packer arranged and connected with the oil pipe, and a sealing spile device which is connected with the on the one-way constant-pressure well cleansing valve and a packer is composed of a sealing outer barrel and a sealing plug. The utility model has the functions such as automatic shrinkage, separated-zone water injection, separated-zone testing, or reverse well cleanout when the packer is not moving, and may be widely applied to oil water injection processes.
Description
One, technical field
The utility model relates to oil exploitation underground water-injection tubing string, the hollow integrated stratified injection water technology tubing string of particularly a kind of cannula type.
Two, background technology
Existing laminated distributor under well water injection string, in the injecting process because of down-hole pressure and temperature fluctuation, make the underground water-injection tubing string produce wriggling up and down, the result causes packing element to damage, the lost of life, packer set lost efficacy, the seperated layer water injection failure, flood effectiveness does not reach designing requirement, thereby influences development effectiveness.
Three, summary of the invention
The purpose of this utility model provides the hollow integrated stratified injection water technology tubing string of a kind of improved cannula type; shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art; the protecting packer packing element is not damaged effectively; guarantee the seperated layer water injection effect effectively, improve the oilfield exploitation effect.
The hollow integrated stratified injection water technology tubing string of cannula type described in the utility model, comprise sleeve pipe, oil pipe and go up test injection well downhole flow regulator, unidirectional level pressure flushing valve and the packer that connects, also comprise the sealing Intubaction device that includes sealed outer cylinder and sealing plug that is connected on described unidirectional level pressure flushing valve and the packer.
Wherein, described sealing Intubaction device also comprises the connector that is connected in described sealed outer cylinder upper end and the lower contact of lower end, and inner chamber is installed on extension pipe and the top connection that plug and upper end thereof connect in turn.Packer is the Y445-115 type, installs in the sleeve pipe at the interlayer place of two oil reservoirs on the sealed outer cylinder.
The utility model has following advantage compared with prior art:
1, owing to adopted the hollow integrated tubular column structure of cannula type, seperated layer water injection effectively, tubing string can freely stretch and packing element is motionless, protects packing rubber sleeve effectively, prolongs its application life.
2, owing to adopted the aforementioned tube rod structure, can realize two-layer dispensing, zonal testing.
3, the replaceable two-layer water nozzle of a pulling is more conducive to seperated layer water injection effectively.
4, back-washable well makes water filling degree etc. better.
Four, description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the utility model intubation seal device structural representation.
Five, the specific embodiment
Referring to Fig. 1, Fig. 2, the hollow integrated stratified injection water technology tubing string of a kind of cannula type, comprise sleeve pipe 1, oil pipe 2 and go up test injection well downhole flow regulator 3, unidirectional level pressure flushing valve 4 and the packer 5 that connects, also comprise the sealing Intubaction device 6 that includes sealed outer cylinder 64 and sealing plug 66 that is connected on described unidirectional level pressure flushing valve 4 and the packer 5, sleeve pipe 1 bottom is artificial bottom of a well 7, is oil reservoir 8 outside the middle part.
Sealing Intubaction device 6 also comprises the connector 63 that is connected in described sealed outer cylinder 64 upper ends and the lower contact 67 of lower end, and inner chamber is installed on plug 66, extension pipe 62 and top connection 61 that its upper end connects in turn, and its external surface is installed on seal 65.Packer is the Y445-115 type, installs in the sleeve pipe at the interlayer place of two oil reservoirs on the sealed outer cylinder 64.
