Abstract
The invention discloses a kind of Multiple-stage underground liquid-sand separator, solve existing oil water separator and block inlet opening because of alluvial sand setting, and then make the problem of separator cisco unity malfunction.This separator comprises central tube and is equidistantly enclosed within the some Settlement Cups on central tube, wherein Settlement Cup cup bottom surface is many faceted pebbles shape, sand setting hole is had at the outer fin root of many faceted pebbles shape bottom surface of cup, the quantity in the sand setting hole in each Settlement Cup is 2 ~ 6, the sand setting hole dislocation of upper and lower Settlement Cup is arranged, the aperture in sand setting hole is 1 ~ 4mm.This separator achieves the separation of liquid, sand, thus guarantees that the single-well injection-production technique in oil field is able to smooth enforcement.
Description
Technical field
The present invention relates to a kind of underground liquid sand separator that field of oil field oil extraction uses.
Background technology
The applicant is in the multilayer uniform-flow-type coalescence oil-water separator of invention in 2010, its patent No. is 201010110839.2, through this onsite application in 2 years, although oil-water separation is good, but have a large amount of sand setting in separator, these sand settings can make the inlet opening on blocking central tube, finally cause water-oil separating to complete.
Summary of the invention
The object of this invention is to provide a kind of Multiple-stage underground liquid-sand separator, solve existing oil water separator and block inlet opening because of alluvial sand setting, and then make the problem of separator cisco unity malfunction.
For achieving the above object, the technical scheme that the application adopts is: Multiple-stage underground liquid-sand separator, comprise central tube and be equidistantly enclosed within the some Settlement Cups on central tube, wherein Settlement Cup comprises cup and cup, cup bottom surface is many faceted pebbles shape, between the outer fin of many faceted pebbles and horizontal line, angle α is 30 ° ~ 60 °, the central tube that the cup of Settlement Cup is corresponding with the annular space between central tube has one group of isometrical inlet opening; Achieved a fixed connection by the mode of locating dowel and locating hole grafting between adjacent two Settlement Cups; On above-mentioned central tube, cover has upper positioning sleeve, is fixed after the lower end of upper positioning sleeve and the spacing hole grafting of uppermost Settlement Cup by screw and central tube, and on the cup of nethermost Settlement Cup, cover has lower positioning sleeve, and lower positioning sleeve is fixed by screw and central tube; It is characterized in that: have sand setting hole at the outer fin root of many faceted pebbles shape bottom surface of cup, the quantity in the sand setting hole in each Settlement Cup is 2 ~ 6, and the sand setting hole dislocation of upper and lower Settlement Cup is arranged, the aperture in sand setting hole is 1 ~ 4mm.
Underground liquid sand separation method: during for underground liquid sand separation, under oil well pump, place the many groups of underground liquid sand separators combined by series system, liquid sand mixed liquor first flows through each Settlement Cup on separator central tube, by the acting in conjunction of many glasss, liquid is significantly reduced in the decrease speed of Settlement Cup, relatively improves the decrease speed of sand.When oil reservoir sand aggregate and precipitate is in Settlement Cup, Settlement Cup is discharged in the sand setting hole via longitudinal upper Heterogeneous Permutation, and liquid then enters pumping passage by the inlet opening of central tube or enters the annular space of Settlement Cup and oil well casing.
Beneficial effect of the present invention:
1, Multistage settling cup is divided into some parts liquid, sand mixed liquor, is controlled by rational pressure reduction, makes each Settlement Cup can independent effect, and longitudinally on Multistage settling cup can share and play a role;
2, the quantity of all inlet openings can design according to the Liquid output of different oil well, ensure that liquid, sand carry out fully effective separation in Settlement Cup;
3, Heterogeneous Permutation sand setting hole bottom Settlement Cup, its role is to enter the sand aggregate and precipitate in Settlement Cup, reduces the decrease speed of liquid in Settlement Cup, the decrease speed of sand relatively to improve;
4, overcome existing all kinds of separation method and there is the difficulty that cannot realize liquid, sand separation, single-well injection-production technique is protected, ensure that technique is normally carried out.
Accompanying drawing explanation
Fig. 1 is the structural representation of Settlement Cup.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the structural representation of Multiple-stage underground liquid-sand separator.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Shown in Fig. 1 composition graphs 2,3: Multiple-stage underground liquid-sand separator of the present invention, comprise central tube 1 and be equidistantly enclosed within the some Settlement Cups 2 on central tube 1, gap is had between adjacent Settlement Cup 2, described Settlement Cup 2, comprise cup 4 and cup 5, wherein cup 4 bottom surface is many faceted pebbles shape, and between the outer fin of many faceted pebbles and horizontal line, angle α is 30 ° ~ 60 °, and faceted pebble and ridge line section potential energy enough make oil droplet collide coalescence, assemble formation larger diameter oil droplet; The central tube 1 that the cup 4 of Settlement Cup 2 is corresponding with the annular space between central tube 1 has one group of isometrical inlet opening 3.
The upper edge of Settlement Cup 2 is the zigzag matched with 4 watts, the cup bottom surface prismatic of Settlement Cup 2 above below, the cup 5 of Settlement Cup 2 has bar v notch v 6, the both sides of cup 5 are fixed with limited post 8 respectively, there is the spacing hole 7 matched with limited post 8 upper end of cup 5, limited post 7 on upper Settlement Cup 2 cup 6 is inserted in the spacing hole 6 in next Settlement Cup 2 cup 5, achieve the connection between Settlement Cup 2, this connected mode plays the effect of stabilizing solution sand separator.
On above-mentioned central tube 1, cover has upper positioning sleeve 9, fixed by screw and central tube after the lower end of upper positioning sleeve 9 and spacing hole 7 grafting of uppermost Settlement Cup 2, on the cup 5 of nethermost Settlement Cup, cover has lower positioning sleeve 11, lower positioning sleeve 11 is fixed by screw and central tube 1, and upper positioning sleeve 9 plays fixing whole Settlement Cup effect with lower positioning sleeve 11.
Have sand setting hole 10 at the outer fin root of many faceted pebbles shape bottom surface of cup 4 in addition, the quantity in the sand setting hole 10 in each Settlement Cup 2 is 2 ~ 6, and the sand setting hole 10 of upper and lower Settlement Cup 2 misplaces and arranges, the aperture in sand setting hole 10 is 1 ~ 4mm.
Under this underground liquid sand separator is arranged on oil well pump, the multicomponent that can be installed in series under oil well pump is from device.This separator by changing the number of the area of passage of inlet opening 3, the number of inlet opening 3 and Settlement Cup 2 and the area of passage in sand setting hole 10, the number in sand setting hole 10 realizes liquid sand separation, and meets on-the-spot actual needs.
The present invention can also be applicable to liquid, the sand separation in other field except oil field.
