Abstract
The utility model discloses a separated injection device and relates to a device which is capable of achieving separated layer water infections. The separated injection device comprises a sleeve and sealing and separating devices. A plurality of sealing and separating devices is arranged inside the sleeve. The sleeve is divided into a plurality of cavities by the plurality of sealing and separating devices. Connecting pipes are arranged inside each cavity. One end of each connecting pipe is arranged in the corresponding cavity of the sealing and separating device. A current control device is arranged at the other end of each connecting pipe, and a water filling opening is arranged on the outer wall of each cavity. According to the separated injection device, the sealing and separating devices can be arranged correspondingly according to waiting water injection layers. Water is injected to corresponding geological stratification through the sleeve.
Description
Technical field
The utility model relates to a kind of flushing device, but particularly a kind of device of seperated layer water injection.
Background technology
Present southern oil field deeply buried reservoir, water injection pressure is high, and injection water quality is not up to standard, oil cylinder corrosion structure is serious, and the pulling side is joined loaded down with trivial details, is hampered, falls, meets that to block phenomenon frequent, cycle is long and success rate is lower, and for many years, zonal injection technology all adopts 1 grade of 2 grades of location water injection through tubing and casing, can't realize the cover guarantor, cause cover to decrease, overlap change seriously, the overhaul probability is high, and the tubing string period of validity is short, potentiality of remaining oil can not fully effectively excavate, and is difficult to satisfy oil field development to the demand of each level.
Summary of the invention
The utility model proposes a kind of device of realizing seperated layer water injection.
A kind of dispenser described in the utility model, comprise sleeve and packing device, described inside pipe casing is fixedly provided with several packing devices, these packing devices are divided into several cavitys with sleeve pipe, be equipped with a tube connector in each cavity, one end of each tube connector all is arranged in the corresponding packing device cavity, and the other end links to each other with flow control apparatus for water, and is equipped with a water filling port on the chamber wall of each cavity.
Preferably, described flow control apparatus for water is valve.
Preferably, described packing device is Y111 type packer.
Preferably, described packing device is Y211 type packer.
Dispenser described in the utility model can be treated to come the corresponding packing device of arranging of water filling layer to corresponding geological stratification water filling by sleeve pipe by basis.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, the 1-sleeve pipe; The 2-packing device.
The specific embodiment
A kind of dispenser described in the utility model, comprise sleeve and packing device 2, the described packing device Y111 of the present embodiment type packer, sleeve pipe described in the utility model 1 inside is fixedly provided with several Y111 type packers, these Y111 type packers are divided into several cavitys with sleeve pipe 1, are equipped with a tube connector in each cavity, and an end of each tube connector all is arranged in the corresponding cavity, the other end links to each other with valve, and is equipped with a water filling port on the chamber wall of each cavity.
During use, open valve, according to the corresponding tube connector of water filling needs conducting, by the water filling port on the chamber wall of corresponding packer cavity current are exported to and to treat accordingly the water filling layer.
The present embodiment is substantially the same manner as Example 1, and difference is that packing device 2 described in the utility model is Y211 type packing device.
