Abstract
The invention discloses a kind of nano silica compound oil displacement agent and flooding methods, oil displacement agent is injected into low oil production area, oil displacement agent is prepared from the following raw materials in parts by weight: 25-40 parts of straight chain fatty acid alkanolamide, 30-60 parts of Alkylbenzensulfonate, 10-15 parts of tetrakis hydroxymetyl phosphonium sulfuric, 13-24 parts of bi-quaternary ammonium salt, 22-30 parts of biological enzyme, 5-10 parts of nano silicon dioxide sol, poly- silicon nano material 5-15 parts, 15-30 parts of glucoside, 10-30 parts and chelating agent 5-10 parts of alkyl glycosides.It contacts underground dewatered oil with oil displacement agent, the abundant displacement of crude oil in rock core is come out, can be used for the secondary oil recovery of low-permeability oil deposit.
Description
Technical field
The present invention relates to technology of reservoir sweep field more particularly to a kind of nano silica compound oil displacement agents and flooding method.
Background technique
Low-permeability oil deposit is polymerized alone can only improve recovery ratio 5% or so on the basis of water drive when object drives, independent surface is living
Property agent drive it is also not high, in addition middle and high infiltration oil reservoir use preferable ternary composite oil-displacing system, because the presence of alkali can cause stratum
And pit shaft fouling, this is extremely disadvantageous for low-permeability oil deposit.Polymer/surfactant binary complex ties up to porous
It can reduce oil water interfacial tension in the flow event of medium, change the wetability of porous media to reduce capillary resistance, make
Emulsification of crude oil forms emulsion, improves oil recovery factor.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of nano silica proposed is multiple
Close oil displacement agent and flooding method.
To achieve the goals above, present invention employs following technical solutions:
A kind of nano silica compound oil displacement agent and flooding method, oil displacement agent are injected into low oil production area, oil displacement agent
It is prepared from the following raw materials in parts by weight: 25-40 parts of straight chain fatty acid alkanolamide, 30-60 parts of Alkylbenzensulfonate, four
10-15 parts of methylol sulfuric acid phosphorus, 22-30 parts of biological enzyme, 5-10 parts of nano silicon dioxide sol, gathers by 13-24 parts of bi-quaternary ammonium salt
5-15 parts of silicon nano material, 15-30 parts of glucoside, 10-30 parts and chelating agent 5-10 parts of alkyl glycosides.
The beneficial effects of the present invention are: contacting underground dewatered oil with oil displacement agent, by the abundant displacement of crude oil in rock core
Out, it can be used for the secondary oil recovery of low-permeability oil deposit.
Specific embodiment
Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described,
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
A kind of nano silica compound oil displacement agent and flooding method, oil displacement agent are injected into low oil production area, oil displacement agent
It is prepared from the following raw materials in parts by weight: 25-40 parts of straight chain fatty acid alkanolamide, 30-60 parts of Alkylbenzensulfonate, four
10-15 parts of methylol sulfuric acid phosphorus, 22-30 parts of biological enzyme, 5-10 parts of nano silicon dioxide sol, gathers by 13-24 parts of bi-quaternary ammonium salt
5-15 parts of silicon nano material, 15-30 parts of glucoside, 10-30 parts and chelating agent 5-10 parts of alkyl glycosides.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
