Description

A kind of horizontal well automatic control water completion tubular column structure
Technical field
The present invention relates to petroleum oil well completions and underground work field, and in particular to a kind of horizontal well automatic control water completion tubular column knot Structure.
Background technique
Horizontal well can significantly improve single well productivity compared with straight well exploitation, be widely applied at home, outside at present.But Long horizontal well difference well section physical property, Produced Fluid Property are variant, there is a problem of that part well section is aqueous high, and aqueous excessively high meeting is significant The economic benefit of horizontal well is reduced, or even horizontal well is caused to break useless result.The side such as well logging, machinery, tracer is mostly used at present Method finds water exit end, then the method blocked using modes such as chemical water shutoff, water pack offs, operation process complexity, measure wind Danger is high, and reliability is bad.It is the automatic tune flow control water installations of representative although controlled level can be played to a certain extent using AICD The aqueous effect of well, but structure is complicated, expense is high, is not widely applied.
Application No. is CN106246143A to provide the water control method and its control water sand control pipe of a kind of water outlet oil reservoir, the dress Set can only for there are the long well section horizontal wells of edge-bottom water, and various different well section physical property can not be coped with, Produced Fluid Property respectively has difference Different long horizontal well, and there are following defects in setting for its device:
The technical solution is actually a Self-expandable packer, is applied to straight well, it is substantially accomplished that envelope Every the annular space of tool and ground interlayer, partition be tool above and below entire well section, i.e., can only it is more than implementation tool or with The complete packing of lower well section.
Summary of the invention
It is an object of that present invention to provide a kind of horizontal well automatic control water completion tubular column structures, can although solving existing apparatus The problem of effective water production control rate still can not effectively keep the output capacity of oil.
The present invention is achieved through the following technical solutions:
A kind of horizontal well automatic control water completion tubular column structure, including punch outer tube, punching inner tube and be uniformly arranged on punching Multiple hydroexpansivity rubber columns on outer wall of inner tube, punching outer concentric tube axle sleeve are located at outside punching inner tube and have between punching inner tube There is appropriately distance, punch and be evenly arranged with multiple first perforation on outer tube along its outer wall, punches equal along outer wall in inner tube It is even to be provided with multiple second perforation, between multiple hydroexpansivity rubber columns independently of one another.
The position of first perforation and the position of hydroexpansivity rubber column correspond, and the aperture of the first perforation and hydroexpansivity rubber The column cap shape of rubber column gel column matches.
The position and biperforate position of first perforation are to shift to install.
The hydroexpansivity rubber column is SAP material or modified hydroexpansivity rubber based on SAP.
The aperture of first perforation is greater than biperforate aperture.The aperture of first perforation is greater than biperforate aperture and sets Set, production fluid it is more largely is gathered in punching outer tube, punching inner tube between, and when it is aqueous gradually increase when, hydroexpansivity Rubber column can have time enough water swelling, and can effectively play the entrance for blocking water flooding.And in conjunction with multiple water Setting independent of each other between swollen property rubber column, can effectively control the moisture in production fluid it is more be retained in punching outer tube, It punches between inner tube, allows hydroexpansivity rubber column to there is longer time to be carried out according to water content different in production fluid independent Expansion, avoid misplacement oily in water exit end production fluid, improve oil yield.
The present invention is when implementing, after the tool tripping in pit shaft, due to having suitable distance, well between punching outer tube, punching inner tube Production fluid in cylinder can enter inner tube along outer tube tapping, finally flow out pit shaft.When production fluid moisture content increases, in water flooding Immersion under, be arranged in the hydroexpansivity rubber column water swelling of outer wall of inner tube, the outer tube tapping of corresponding position blocked, to control Water flooding processed enters pit shaft, controls the moisture content of pit shaft production fluid.The present invention by by between multiple hydroexpansivity rubber columns each other Independent setting enables to part is aqueous to increase the rubber column water swelling that not will cause large area, to fuel-displaced yield effect It is smaller.Simultaneously as gravitational differentiation, water flooding is usually located at lower wellbore, and crude oil is located at upper wellbore, goes out to lower part The closure of water section has no effect on the continuation output of crude oil, further mitigates the influence for blocking High water cut section to yield.
Compared with prior art, the present invention having the following advantages and benefits:
The present invention can automatically block High water cut net horizontal section by the improvement to structure, avoid horizontal well It looks for, a series of activities of water blockoff, with structure, simple, advantage of lower cost, construction is simple are easy, are not necessarily to final-period management, especially The present invention can also control water outlet on the basis of guarantee fuel-displaced yield.
