Description
Technical field
The invention belongs to oil field development technical field, more particularly to a kind of oil recovery side of utilization alkaline electrolysises water drive oil
Method.
Background technology
Oil exploitation, after primary oil recovery and secondary oil recovery, there is also about 2/3rds crude oil and is trapped in oil reservoir, by
In the effect of capillary force, this part trap is stayed in thinner hollow billet duct, this partly oily displacement out, depend merely on increase
Pressure reduction is difficult to accomplish.In tertiary oil recovery technology, chemical flooding is one of important oil recovery technique, and including polymer flooding, live in surface
Property agent drive, caustic waterflooding and three kinds of matching used ternary composite drivings.However, all there is certain technology limitation in all kinds of chemical floodings
Property.Surfactant flooding has that activating agent sweep efficiency is low, oil displacement efficiency is poor, adsorption losses are more serious, activating agent is used
Amount is big, high cost, pollution environment the shortcomings of.Alkali drive occurs in alkali drive evolution and destructively descends rock composition, easily form thing
Therefore and the basic residual excessively factor such as destruction equipment when meeting faintly acid crude oil, quickly caustic waterflooding be just eliminated.Polymer flooding
There is also this follow-up production fluid difficult, pollution the problems such as.After ternary composite driving enters fouling peak period, machine-pumped oil well is due to knot
Dirt, leads to frequent holddown, and operating cost increases；Alkali in injection liquid and the Ore in stratum and the fluid in stratum occur anti-
Should, produce substantial amounts of inorganic scale, in stratum accumulation, the sour gas producing during neutralization reaction knows from experience corrosion pipeline material；
Do not consider the surfactant that soda acid generates when adding surfactant, will result in process and repeat, and increased cost；
These all have a strong impact on ternary composite driving exploitation benefit.But chemical combined flooding either improves oil recovery in tertiary oil recovery method
Rate amplitude, or reduces cost has very big development potentiality, therefore, develops efficient, cheap, non-environmental-pollution surface and lives
Property agent and oil displacement system are extremely urgent, to adapt to the situation that high-water-cut stage old filed improves recovery ratio further.
Content of the invention
It is an object of the invention to provide the oil recovery work of a kind of environmental protection, efficient, cheap utilization alkaline electrolysises water drive oil
Process, the method is active strong, and displacement efficiency is high；Environmental protection, non-secondary pollution；Raw material is easy to get, with low cost；Work
Skill simple it is easy to the advantages of construction.
The present invention is achieved through the following technical solutions:
A kind of method of utilization alkaline electrolysises water drive oil, using alkaline electrolysises water drive: electrolyzed alkaline water is mixed with water filling
Obtain oil driving liquid and be directly injected into water injection well carrying out water drive.
A kind of method of utilization alkaline electrolysises water drive oil, using electrolyzed alkaline water single well stimulation: by electrolyzed alkaline water and note
Water is mixed to get liquid injection producing well of handling up, the vexed well of closing well after injection, then opening well and making production again, and closed time is because of the viscosity of crude oil
Different and different, needing to refer to core physical simulation oil displacement experiment determines throughput time, and general closing well closed time is 1h-6d.
In the method for the both the above displacement of reservoir oil, the interpolation concentration of described oil driving liquid or liquid neutral and alkali of handling up electrolysis water needs basis
Oil driving liquid is determined with formation water salinity Experiment of Compatibility, on the basis of not producing alkaline sedimentation, real with the core physical simulation displacement of reservoir oil
Test as reference frame, select optimum concentration, the ph of general oil driving liquid or liquid of handling up is more than or equal to 8.
Described closed time determines according to core physical simulation oil displacement experiment result, and described closed time is general 1h-6d.

Water, after electrolysis installation is electrolysed, obtains strong basicity electrolytic aqueous solution, alkaline electrolysises through infiltration membrance separation
Water ph value is in 10-14.
Electrolysis water activity is stronger, needs sealing or airtight preservation during transport, and effect is unaffected substantially.Or
Job site is prepared, to ensure its active effect.
Electrolysis water be by water under electrolysis, with barrier film separate and generate acidic electrolytic water and electrolyzed alkaline water total
Claim.Electrolyzed alkaline water is the electrolysis water that water generates through electrolysis, is made up of 5-6 micel, and normal water is by 13 micels
Composition, this water activity is big, surface tension very little, and penetration is strong, dissolubility is high, has higher negative oxidation-reduction potential, is
A kind of soda acid solvent of green, is a kind of reaction cosolvent again.Therefore, electrolyzed alkaline water can increase its infiltration on stratum and expand
Scattered speed, reduce interfacial tension emulsified crude oil, strengthen crude oil fluidity, improve washing oil effect, with conventional surfactant drive and
Ternary composite driving is compared, and oil displacement efficiency is higher；Although electrolyzed alkaline water is in alkalescence, not as Caustic soda has counter ion, tool
There are stronger corrosion and fouling hidden danger, there is stronger rust inhibition, protection equipment and pipeline, alkali resistance Precipitation Potential on the contrary
By force；In addition, this water does not pollute to oil reservoir and environment, eventually revert to conventional water, there is no chemical contamination and subsequently secondary place
Reason cost.
The present invention has the advantages and positive effects that:
(1) electrolyzed alkaline water activity is high, and permeability is strong, big in oil reservoir diffusion rate, and washing oil displacement of reservoir oil degree is high.
(2) alkaline electrolysises water energy effectively reduces that crude oil surface tension is low, and emulsifying effectiveness is good.
