Description
Technical field
The invention belongs to oil field development technical field, and in particular to a kind of ternary composite driving compositionss and its in chemical flooding
Application.
Background technology
With continually developing for oil field, Chinese land main force oil field enters high recovery percent of reserves, high water cut stage.Old filed is steady
Produce, volume increase becomes the important topic put in face of oil field development worker.Chemistry with polymer flooding, ternary composite driving as representative
Drive the stable yields that raising recovery efficiency technique is domestic crude oil and be 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 has been enter into expanding 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 scene applies scale.
In ternary composite driving, most representational surfactant product is heavy alkylbenzene sulfonate and petroleum sulfonate.Two
Person's production needed raw material heavy alkyl benzene, distillate are cheap and easy to get, and the relatively conventional surfactant of simple production process, cost
It is low.But, as industrial by-products heavy alkyl benzene production capacity is limited, constrain the scale of heavy alkylbenzene sulfonate scene application;And
Petroleum sulfonate is excessively complicated due to raw materials for production aromatic rich cut oil component, causes properties of product easily to receive fraction oil quality shadow
Ring, product stability has much room for improvement.And, heavy alkylbenzene sulfonate and petroleum sulfonate salt tolerant and resistance to divalent ion ability compared with
Difference, it is difficult to be applied to high salinity, the oil reservoir of high divalent ion content.
Compared with other classes of surfactant, betaine type amphoteric surfac-tant has many excellent performances, such as pole
Good stability in hard water, salt tolerance, low toxicity, easily biological-degradable, moderate performance compatibility are good etc..Additionally, beet alkali surface activator
Also there is preferable chemical stability, good emulsibility, dispersibility and antistatic behaviour, some types also have sterilization and press down mould
Property, viscoelasticity etc., range of application is quite varied.
Conventional Long carbon chain dimethyl betaine is long due to single hydrophobic chain, its dissolubility is poor have impact on it is actually used.

The problems such as be difficult to obtain the large-scale raw material of industry.And, the alkyl polyoxyethylene ether glycine betaine of Ju Beite structures and octadecane
The single dose of base hexyl carboxybetaine is difficult to reach ultralow interfacial tension with crude oil.For example, cetyl Polyethylene oxide (3) ether
The ultralow interfacial tension scope that hydroxypropyl carboxybetaine could need to be reached with crude oil in the case of addition weak base sodium carbonate
(10-3The mN/m orders 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.
