Description
Technical field
The present invention relates to a kind of displacement compositions and preparation method thereof suitable for high salinity stratum.
Background technology
By the exploitation of decades, many oil fields in China all enter high water cut stage, and yield is faced with decline, and development is strong
It is to improve the important channel of oil recovery to change oil recovery.Tertiary oil recovery is to continue exploitation ground using means such as physics, chemistry and biologies
Under remaining oil, the method that oil recovery factor is improved with this.The research that application surface activating agent recovers the oil in oil exploitation rises
Start from earlier 1930s, be developed so far, be an important means for improving recovery ratio in oil field, theoretical and
There is prodigious progress in practice.Currently, having basically formed following several injection systems：Active water drive, foam flooding, lower bound
Face tension system displacement of reservoir oil etc..After oil field enters high water-cut stage, remaining oil is with discontinuous oil film by trap in reservoir rocks
In hole, the two main power acted on oil droplet are viscaps, if selecting suitable surfactant body
System reduces the interfacial tension between grease, the interfacial tension between oil reservoirs grease is made to be down to relatively low or ultralow value from 20~30mN/m
(10-3~10-4MN/m), resistance caused by oil droplet deformation when remaining oil being made to move just can be reduced, to greatly improve displacement of reservoir oil effect
Rate.
Most still petroleum sulfonates of oil recovery surfactant application, the oil refining by-product such as heavy alkylbenzene sulfonate change
Property surfactant, the characteristics of this kind of surfactant is that materials are extensive, cheap, still, this kind of surfactant
A series of problems, such as there is performances to be not sufficiently stable, and the especially resistance to bivalent cation performance of salt tolerant is poor, is not applied for high mineralization
The oil field block of degree.The novel surfactant that multiple active function groups are introduced in the same molecule, is greatly improved surface
Activity, and synergistic effect may be will produce, increase salt-resistance.Patent U.S.Pat.No.4436672A alkylols and shrink
Glycerine reaction obtains alkylol polyglycidyl ether, then carries out sulfonation, obtains a kind of anion-nonionic surfactant；Patent
U.S.Pat.No.4466891A provides a kind of alkyl phenol polyoxyethylene ether propane sulfonic acid salt；Patent
For U.S.Pat.No.2011015111A1 with alhpa olefin and 1, the reaction of bis- chloro- 2- propyl alcohol of 3- generates the ether containing chloro base, then into
Row sulfonating reaction obtains a kind of novel anion surfactant of sulfo group containing there are two.
Complex oil displacing technology is also a kind of method of important raising oil recovery, polymer, surfactant and alkali
The ASP Oil-Displacing Technology of formation has carried out some field tests at home and abroad, achieves 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, in use, to stratum
Huge injury is brought with oil well etc., leads to that the fouling of oil recovery well shaft is serious, Produced Liquid processing is difficult, and is used
Surfactant be not easy to be biodegradable, and also have certain harmfulness to human body, such as：1991, Zhao Guoxi existed《It lives on surface
Property agent physical chemistry》P495；1994, Liu Cheng《Surfactant is complete works of》Content disclosed in P35.
Various drawbacks make the application of ASP Oil-Displacing Technology be very limited.In contrast, polymer and surface
The binary combination flooding formula that activating agent is formed, due to being not added with alkali, thus can be to avoid the above drawback.But it is added in no alkali
In the case of, the activity of conventional surfactant can be greatly reduced, and the requirement of the displacement of reservoir oil is not achieved.It is introduced in the same molecule more
The novel surfactant of a active function groups is greatly improved surface-active, and may will produce synergistic effect, increases anti-
Salt.Alkylol polyglycidyl ether is obtained by the reaction with glycidol in patent U.S.Pat.No.4436672A alkylols, then
Sulfonation is carried out, a kind of anion-nonionic surfactant is obtained；Patent U.S.Pat.No.2011015111A1 is with alhpa olefin and 1,3-
Two chloro- 2- propyl alcohol reactions generate the ether containing chloro base, then carry out sulfonating reaction, obtain a kind of novel sulfo group containing there are two
Anion surfactant.Patent U.S.Pat.No.4466891A provides a kind of alkyl phenol polyoxyethylene ether propane sulfonic acid salt,
Water-soluble and salt-resistance increases.
But the oil displacement efficiency using the displacement composition of existing surfactant on high salinity stratum is to be improved.
