Description
Technical field
The present invention relates to a kind of oil exploration equipment, the multistage continuous ripening jar of particularly a kind of hydrophobic associated polymer.
Background technology
Polymer flooding is as one of important means of oil field development stable yields or raising the output, and at home and abroad onshore oil field has obtained extensive use.Major oil districts such as the grand celebration of China, triumph, Kelamayi have all carried out field test and have obtained immense success.Particularly Daqing oil field has got into the large-scale industrial application stage, and on the basis of waterflood recovery efficiency factor 42%, recovery ratio has improved 12% again behind the enforcement polymer flooding, makes ultimate recovery reach 55%.
Hydrophobic associated polymer is one type of polymer that on the hydrophily macromolecular chain, has a small amount of hydrophobic grouping; When the polymer concentration in the aqueous solution acquires a certain degree; The hydrophobic effect of hydrophobic grouping is associated polymer, has increased the hydrodynamics volume, thereby produces tangible viscosifying action.In salt solution, the hydrophobic association effect strengthens, and shows certain salt-resistance.Such material can be applicable in the polymer flooding pool technology under the high salinity, but because the introducing of hydrophobic grouping, its solvability in water also reduces.The dissolving, curing problem of polymer is one of technical barrier of this base polymer industrial applications of restriction always.The dissolving, curing time of hydrophobic associated polymer is significant to the offshore oilfield polymer displacement of reservoir oil; The long curing time means that needs increase the quantity or the volume of slaking jar; Certainly will conflict with offshore platform narrow space and limited carrying, thereby limit polymer displacement of reservoir oil tech applying of oil field at sea.
The dissolving, curing of polymer shortens the curing time of polymer in occupation of important position very in the polymer displacement of reservoir oil process, improves the treatment effeciency of polymer, reduces ripening device used occupation space simultaneously and offshore platform is recovered the oil has important practical significance.
At present, in the polymer displacement of reservoir oil process that occurs on market and the data dissolving, curing equipment of polymer mainly by the slaking tank body, be located at medium import, media outlet on the slaking jar; Axially be installed on shaft in the slaking tank body, be located at the paddle on the shaft and drive the drive motors of shaft rotation along the slaking tank body.Polymer in the above-mentioned dissolving, curing equipment is entered into by the medium import in the mixing chamber of slaking tank interior and is discharged by media outlet through after the stirring of paddle; The viscosity of medium and degree of mixing and mixture homogeneity are not enough; And the curing time of polymer is longer, and production efficiency is lower.
Summary of the invention
To the deficiency that prior art exists, it is big to the invention provides a kind of treating capacity, quick dissolving, curing hydrophobic associated polymer, and can obtain the hydrophobic associated polymer dissolving, curing device that viscosity is higher, mix.
For realizing above-mentioned purpose, the invention provides following technical scheme: the multistage continuous ripening jar of a kind of hydrophobic associated polymer includes the slaking tank body, is located at medium import, media outlet on the slaking jar; Axially be installed on shaft in the cavity of slaking tank body along the slaking tank body, be located at the paddle on the shaft and drive the drive motors of shaft rotation; It is characterized in that: be provided with a dividing plate of axially installing along the slaking tank body in the cavity of said slaking tank body at least; The axial both sides of dividing plate form independently mixing chamber respectively, and are evenly equipped with some flowing holes that run through dividing plate on the dividing plate; Shaft penetrates dividing plate and extends in each mixing chamber, is on the shaft in each mixing chamber to be respectively equipped with paddle, and is provided with seal between shaft and the dividing plate; Described dividing plate is provided with anti-loading in mixture and puts.
Adopt technique scheme,, the pocket in the slaking tank body is a plurality of relatively independent mixing chambers with this through with at least one dividing plate of axially installing along the slaking tank body is set in the slaking tank body; And extend on the shaft in each mixing chamber and be respectively equipped with independently paddle; Make this slaking tank body have a plurality of mixing chambers that can work independently, in use, after the medium import entering of hydrophobic associated polymer by the slaking tank body; Mixing through the several times mixing chamber is stirred; Viscosity, degree of mixing and the mixture homogeneity of the hydrophobic associated polymer of being discharged by media outlet are improved, and continuable feed are carried out in the medium import, make the work of carrying out that the slaking tank body continues; In the viscosity, degree of mixing and the mixture homogeneity that guarantee hydrophobic associated polymer, also improved production efficiency.(viscosity and the degree of mixing that are in the medium import department mixing chamber are minimum because viscosity that mixes relatively in each mixing chamber of being kept apart by dividing plate and degree of mixing are different; And the viscosity and the degree of mixing that are in the media outlet place mixing chamber are the highest); In order to prevent that the hydrophobic associated polymer in higher level's mixing chamber in the course of the work is back in the mixing chamber of subordinate; Between shaft and dividing plate, be provided with seal, on dividing plate, be provided with and prevent loading in mixture putting; Reach anti-purpose of mixing, further guaranteed viscosity, degree of mixing and the mixture homogeneity of hydrophobic associated polymer.
The present invention further is set to: prevent loading in mixture to put including the convexity of being located at some with the flowing hole corresponding settings of dividing plate on the one end end face of slaking tank body top, offer an end and mixing chamber conducting on each convexity respectively, the through hole of the other end and flowing hole conducting.
Adopt technique scheme; Be in and have pressure and delivery flow after the interior hydrophobic associated polymer of mixing chamber stirs through paddle; Impel a part hydrophobic associated polymer can be along the dividing plate advection; In the processing procedure of slaking tank body, should keep of the conducting of each mixing chamber through flowing hole on the dividing plate, prevent that again the hydrophobic associated polymer in higher level's mixing chamber is back in the mixing chamber of subordinate through flowing hole; The anti-convexity that loads in mixture in putting then can play the effect of keeping out advection hydrophobic associated polymer on dividing plate, and the through hole on the convexity can impel the conducting of subordinate's mixing chamber and higher level's mixing chamber.
The present invention further is set to: the seal between shaft and the dividing plate is the sealing ring that is sheathed between shaft and the dividing plate, and the sealing ring is with dividing plate and is fixedly connected, and is matched in clearance between sealing ring and the shaft.
Adopt technique scheme, through above-mentioned setting, seal not only can keep the sealing between shaft and the dividing plate, simultaneously shaft is rotated normally.
The present invention further is set to: paddle is the wide rachis stream of a last pushing-type oar; Paddle includes the wheel hub of fixing with the shaft socket and is distributed in 3-4 blades on the wheel hub; Each root of blade and shaft root and be between 40-60 degree, blade tip and angle b perpendicular to the shaft plane perpendicular to the angle a on shaft plane be in 15-30 spend between.
Adopt technique scheme, the design of special blade and angle has reduced the shear action that stirs, and the hydrophobic associated polymer after can guaranteeing to dissolve has higher viscosity, also can cut down the consumption of energy under the situation of assurance mixing quality.
Below in conjunction with accompanying drawing the present invention is further described.
