Description
Technical field
The invention belongs to oil field development technical fields, and in particular to a kind of ternary composite driving composition and its in chemical flooding
Application.
Background technique
With continually developing for oil field, the land main force oil field of China enters high recovery percent of reserves, high water cut stage.Old filed is steady
It produces, volume increase becomes important topic of the pendulum in face of oil field development worker.Using polymer flooding, ternary composite driving as the chemistry of representative
It drives the stable yields that raising recovery efficiency technique is domestic crude oil and is made that significant contribution.In Daqing oil field, using heavy alkylbenzene sulfonate
Strong base ternary composite driving (sodium hydroxide/heavy alkylbenzene sulfonate/polymer) technology of surfactant, which has entered, expands chemical industry
The industry application stage；Using the Weak Base ASP Flood (sodium carbonate/petroleum sulfonate/polymer) of petroleum sulfonate surfactant
The field test of technology also takes successfully and continues to expand field application scale.
Most representative surfactant product is heavy alkylbenzene sulfonate and petroleum sulfonate in ternary composite driving.Two
Raw material heavy alkyl benzene, distillate needed for person produces are cheap and easy to get, and the relatively conventional surfactant of simple production process, cost
It is low.But, since industrial by-products heavy alkyl benzene production capacity is limited, the scale of heavy alkylbenzene sulfonate field application is constrained；And
Petroleum sulfonate causes properties of product vulnerable to fraction oil quality shadow since raw materials for production aromatic rich cut oil component is excessively complicated
It rings, product stability is to be improved.Moreover, heavy alkylbenzene sulfonate and petroleum sulfonate salt tolerant and resistance to divalent ion ability compared with
Difference, it is difficult to the oil reservoir applied to high salinity, high divalent ion content.
Compared with other classes of surfactant, there are many excellent performances, such as pole by betaine type amphoteric surfac-tant
Good stability in hard water, salt tolerance, low toxicity, easily biological-degradable, the mild compatibility of performance are good etc..In addition, beet alkali surface activator
Also there is preferable chemical stability, good emulsibility, dispersibility and antistatic property, certain types also have sterilization and suppression mould
Property, viscoplasticity etc., application range is very extensive.
For conventional Long carbon chain dimethyl betaine since single hydrophobic chain is too long, dissolubility is poor to affect actual use.

A series of betaine type surfactant oil displacements.Such as aryl alkyl glycine betaine (CN102618244A), octadecyl hexyl first
Base carboxybetaine (Song Hongjuan, fine chemistry industry, 2015:32 (6)) and the alkyl polyoxyethylene ether beet with Ju Beite structure
Alkali (CN101745343A) etc..But aryl alkyl glycine betaine and octadecyl hexyl carboxybetaine preparation process compare
It is complicated；Synthesis material used in the alkyl polyoxyethylene ether glycine betaine of Ju Beite structure occupies shellfish Extra Old due to production technology and catalyst
The problems such as be difficult to obtain the large-scale raw material of industry.Moreover, the alkyl polyoxyethylene ether glycine betaine and octadecane of Ju Beite structure
The single dose of base hexyl carboxybetaine is difficult to reach ultralow interfacial tension with crude oil.For example, cetyl polyoxyethylene (3) ether
The ultralow interfacial tension range that hydroxypropyl carboxybetaine need to could reach in the case where adding weak base sodium carbonate with crude oil
(10-3The mN/m order of magnitude and following).Octadecyl hexyl carboxybetaine need to be with hexadecyldimethyl benzyl ammonium carboxybetaine and double
Dodecyl methyl carboxybetaine compounding could reach ultralow interfacial tension with crude oil.
