Description
Technical field
The present invention relates to a kind of displacement composition for high salinity reservoir and preparation method thereof.
Background technology
Through the exploitation of decades, many oil fields of China all enter high water cut stage, and yield is faced with decline, and development is strong
It is the important channel for improving oil recovery to change oil recovery.Tertiary oil recovery is, using means such as physics, chemistry and biologies, to continue out
Remaining oil under fief, in the method that this improves oil recovery factor.Recover the oil using surfactant in oil exploitation
Research originates in earlier 1930s, is developed so far, and has been an important means for improving recovery ratio in oil field,
There is very big progress in theory and practice.At present, following several injection systems have been basically formed：Active water drive,
Foam flooding, low interfacial tension system displacement of reservoir oil etc..After oil field enters high water-cut stage, remaining oil is with discontinuous oil film quilt
In the hole of reservoir rockses, it is viscap to act on oil droplet two main power for trap, if selected
Suitable surfactant system, reduces the interfacial tension between profit, make interfacial tension between oil reservoirs profit from 20～
30mN/m is down to relatively low or ultralow value (10-3～10-4MN/m), just can reduce oil droplet deformation when moving remaining oil to be brought
Resistance, so as to greatly improve oil displacement efficiency.
The oil refining by-product such as the most or petroleum sulfonate of oil recovery surfactant application, heavy alkylbenzene sulfonate is modified
Surfactant, the characteristics of this kind of surfactant be draw materials it is extensive, cheap, but, this kind of surfactant
There is also performance to be not sufficiently stable, salt tolerant especially the poor-performing of resistance to bivalent cation a series of problems, such as, it is impossible to suitable for height
The oil field block of salinity.The novel surfactant of multiple active function groups is introduced in same molecule, can be carried significantly
High surface, and synergism may be produced, increase salt-resistance.Patent U.S.Pat.No.4436672A alkane
Base alcohol obtains alkylol polyglycidyl ether with (+)-2,3-Epoxy-1-propanol reaction, then carries out sulfonation, obtains a kind of anion-nonionic table
Face activating agent；Patent U.S.Pat.No.4466891A provides a kind of alkylphenol polyoxyethylene propane sulfonic acid salt；Patent
U.S.Pat.No.2011015111A1 generates the ether containing chloro base, Ran Houjin with alhpa olefin and the reaction of bis- chloro- 2- propanol of 1,3-
Row sulfonating reaction, obtains a kind of new anion surfactant containing two sulfo groups.
Complex oil displacing technology is also a kind of method of important raising oil recovery, polymer, surfactant and alkali shape
Into ASP Oil-Displacing Technology China and foreign countries carried out some field tests, achieve good oil displacement efficiency.But it is existing
In some ternary composite oil-displacing systems, the alkali containing high concentration, such as sodium hydroxide, sodium carbonate etc., in use,
Huge injury is brought to stratum and oil well etc., the problems such as cause oil recovery well shaft fouling serious, Produced Liquid difficult treatment,
And the surfactant for being used is difficult to be biodegradable, and also there is certain hazardness to human body, such as：1991,
Zhao Guoxi exists《Surfactant physical chemistry》P495；1994, Liu Cheng《Surfactant is complete works of》Institute in P35
Disclosure.
A variety of drawbacks cause the application of ASP Oil-Displacing Technology to be very limited.By contrast, polymer and surface are lived
Property dosage form into binary combination flooding formula, due to being not added with alkali, thus above drawback can be avoided.But add in no alkali
In the case of entering, the activity of conventional surfactant can be greatly reduced, and not reach the requirement of the displacement of reservoir oil.In same molecule
The novel surfactant of multiple active function groups is introduced, surface activity is greatly improved, and collaboration may be produced and make
With increase salt-resistance.Patent U.S.Pat.No.4436672A alkylol obtains alkylol bunching with (+)-2,3-Epoxy-1-propanol reaction
Water glycerin ether, then carries out sulfonation, obtains a kind of anion-nonionic surfactant；Patent
U.S.Pat.No.2011015111A1 generates the ether containing chloro base, Ran Houjin with alhpa olefin and the reaction of bis- chloro- 2- propanol of 1,3-
Row sulfonating reaction, obtains a kind of new anion surfactant containing two sulfo groups.Patent U.S.Pat.
No.4466891A provides a kind of alkylphenol polyoxyethylene propane sulfonic acid salt, and water solublity and salt-resistance increase.
But, had much room for improvement using oil displacement efficiency of the displacement composition of existing surfactant on high salinity stratum.
