Description
Technical field
The utility model relates to the used a kind of instrument of oil recovery field, oil field water injection well, belongs to a kind of lesser calorie apart from segmentation water distribution packer.
Background technology
The water injection technology of field use is main with bridge-type eccentric water distribution technology at present, receives the restriction of pulling operating distance, and its card distance is generally more than 7 meters.Two little one anti-, technology water distribution card such as integrated is apart from less relatively with one heart, but exist test technology complicated, use the shortcoming that progression is limited, testing efficiency is low, be difficult to satisfy further segmentation needs of taping the latent power of oil field late high water content period development phase.
Summary of the invention
In order to solve the problem that exists in the background technology; The utility model provides a kind of lesser calorie apart from segmentation water distribution packer, and this instrument becomes one two-stage bridge-type eccentric injection well downhole flow regulator and one-level packer, has realized two intervals of one-level water distribution packer injection allocation; Dwindle water distribution card distance, improve to survey and transfer efficient.
The technical scheme of the utility model is: this lesser calorie comprises top connection and test short circuit apart from segmentation water distribution packer, and the test short circuit is connected through tubing thread with top connection; The top connection lower end is connected with upper joint sleeve, and centralizer body is housed in the upper joint sleeve, and the upper joint sleeve lower end connects main body; Centralizer body is fixedly connected with main body with cock through set bolt, and main body lower end outer wall is connected with intermediate connecting sleeve, and main body lower end inwall is connected with central tube; Central tube is provided with guide way in the top, is provided with the well-flushing sliding sleeve in the annular space outside the central tube of main body below, and the intermediate connecting sleeve lower end connects glue tube base, protection packing element, spacer ring, cartridge; The cartridge below is provided with adapter sleeve, and adapter sleeve is connected with clip spring seat through the deblocking pin, and clip spring seat is with setting sleeve outward; The setting sleeve upper end is connected with adapter sleeve through setting pin; Setting sleeve is equipped with jump ring in the lower end, and the setting sleeve outer wall is with lower joint sleeve, and lower joint sleeve is connected with lower contact; Be provided with between lower contact and the setting sleeve and set piston, set the corresponding central tube of piston and have inlet opening.
The utlity model has following beneficial effect: lesser calorie becomes one two-stage eccentric injection mandrel and one-level compression packer apart from segmentation water distribution packer, and two seating nipples of two-stage eccentric injection mandrel are reduced to one.Drop into the binary channels water distribution plug in the eccentric orfice of seating nipple, two water nozzles are housed on this blanking plug, corresponding lesser calorie is apart from segmentation water distribution packing element two intervals up and down respectively.When carrying out flow allocating; A pulling can be allocated two water filling intervals simultaneously; When having solved two layers of the common bridge-type eccentric injection well downhole flow regulator of employing two-stage injection allocation; Receive the fabrication of pulling behaviour distance bound apart from bigger problem, make the water distribution card, make simultaneously to survey and transfer efficient to be improved apart from narrowing down to 0.7 meter by original 7 meters.Because lesser calorie has adopted eccentric branch to annotate structure apart from the water distribution packer, not limited by progression when therefore using.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing, this lesser calorie comprises top connection 2 and test short circuit 1 apart from segmentation water distribution packer, and test short circuit 1 and top connection 2 are connected through tubing thread; Top connection 2 lower ends are threaded with upper joint sleeve 5 spiral shells, are provided with sealing ring 3 between top connection 2 and the upper joint sleeve 5, and centralizer body 4 is housed in the upper joint sleeve 5; The upper joint sleeve 5 lower ends main body 8 that is threaded, centralizer body 4 is fixedly connected with main body 8 with cock 7 through set bolt 6, in main body 8 eccentric orfices blanking plug 9 is housed; The eccentric orfice at blanking plug 9 places communicates with the eccentric orfice at cock 7 places, and main body 8 lower end outer wall threads are connected with intermediate connecting sleeve 10, and main body 8 lower end inner threads are connected with central tube 13; Central tube is provided with guide way 12 in 13 tops, and guide way 12 is connected with main body 8 through key 11, is provided with well-flushing sliding sleeve 14 in the annular space outside the central tube 13 of main body 8 belows; The well-flushing sliding sleeve 14 sealing ring holder 16 that has been threaded is equipped with backbone sealing ring 15 in the sealing ring holder 16, intermediate connecting sleeve 10 lower ends connect glue tube base 17, protection packing element 18, spacer ring 19, cartridge 20; Glue tube base 17 lower end screw threads are connected with adapter sleeve 21, and adapter sleeve 21 is connected with clip spring seat 24 through deblocking pin 23, and clip spring seat 24 is with setting sleeves 26 outward; Setting sleeve 26 upper ends are connected with adapter sleeve 21 through setting pin 22; Setting sleeve is equipped with jump ring 25 in 26 lower ends, and setting sleeve 26 outer walls are with lower joint sleeve 28, and lower joint sleeve 28 is threaded with lower contact 29; Be provided with between lower contact 29 and the setting sleeve 26 and set piston 27, set piston 27 corresponding central tubes 13 and have inlet opening.
During packer setting, central tube 13 is suppressed, pressure gets into through the hole of central tube 13 bottoms; Promotion sets on the piston 27 and moves; Promote setting sleeve 26, cut off and set pin 22, jump ring 25 is stuck on the clip spring seat 24 can't move down; Setting sleeve 26 promotes adapter sleeve 28 extruding packing elements simultaneously, makes packer setting.During water filling; Central tube comes the up and down inlet opening while feed liquor of water from seating nipple 8; Get into packer top oil reservoir behind the water nozzle on the last inlet opening water inlet process blanking plug 9; Descending behind 9 times water nozzles of following inlet opening water inlet process blanking plug along the annular space between intermediate connecting sleeve 10 and seating nipple 8 main bodys, walk around packer through the well-flushing passage and get into lower floor.During well-flushing, oil sets annular space comes water to push well-flushing sliding sleeve 14 open, walk around packer through the well-flushing passage and get into lower floor, once more during water filling under central tube pressure well-flushing sliding sleeve 14 playback again make about zonal isolation.During deblocking, the upper lifting pipe post is cut off deblocking pin 23, and the packing element homing is put, the packer deblocking.
