Description

Salt tolerant displacement composition and preparation method thereof
Technical field
The present invention relates to a kind of salt tolerant displacement composition 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 from 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 accessory substance such as the most or petroleum sulfonate of oil recovery surfactant application, heavy alkylbenzene sulfonate is modified Surfactant, be the characteristics of this kind of surfactant 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 synergy may be produced, increase salt-resistance.Patent U.S.Pat.No.4436672A alkane Base alcohol obtains alkylol polyglycidyl ether with glycidol 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 APES propane sulfonic acid salt；Patent U.S.Pat.No.2011015111A1 generates the ether containing chloro base, Ran Houjin with alhpa olefin and the chloro- 2- propyl alcohol reaction of 1,3- bis- 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 NaOH, sodium carbonate, 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 harmfulness 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 adding without 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-active 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 glycidol 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 chloro- 2- propyl alcohol reaction of 1,3- bis- Row sulfonating reaction, obtains a kind of new anion surfactant containing two sulfo groups.Patent U.S.Pat. No.4466891A provides a kind of APES propane sulfonic acid salt, and water-soluble and salt-resistance increases.
