Description
Technical field
It is living with compound surface that the present invention relates to petroleum recovering technical fields more particularly to a kind of high salinity reservoirs displacement of reservoir oil
Property agent composition.
Background technique
Petroleum is a kind of sticky, dark brown liquid, referred to as " industrial blood ".There are stone in upper crustal some areas
Oil storage.Main component is the mixture of various alkane, cycloalkane, aromatic hydrocarbon, while being also non-renewable natural resources,
Irreplaceable role is played in terms of the energy, industrial chemicals and defense strategy.The exploitation of petroleum and oil field
Development process can be divided into three different stages: primary oil recovery, secondary oil recovery and tertiary oil recovery.Primary oil recovery and secondary oil recovery
It is all the oil recovery technique carried out using physical method.Wherein primary oil recovery is the self-spray for fully relying on the natural energy of bottom and carrying out
Exploitation, average are harvested less than 15%.After the completion of secondary oil recovery refers to primary oil recovery, i.e., using outer after stratum energy release
In the oil recovery technique of water filling or the gas injection of supplement energy, recovery ratio is about 30%-40%.As secondary oil recovery is after
The moisture content of phase, oil field mining liquid correspondingly gradually increase, and the economic benefit of oil extraction significantly decays.Secondary oil recovery descendant
Further increase oil recovery factor using distinct methods, the new technology used is referred to as tertiary oil recovery technology, also known as strengthens
Oil recovery technique.
Tertiary oil recovery refers to by injecting the oil production method that chemical substance displaces crude oil to underground, also known as improves recovery ratio
(EOR) method.There are many method for improving oil recovery, mainly have following some: note surfactant；Polymer injection thickening
Water；Caustic waterflooding is driven；Infuse CO2It drives；Note alkali adds polymer flooding；Inert gas injection drives；Infuse hydrocarbon miscible flooding；Combustion in situ；Steam injection
Drive etc..Wherein, surfactant flooding is that a kind of recovery ratio effect that improves is good, applied widely, the chemical flooding with development potentiality
Oil tech, most of oil field obtains relatively broad application at home at present.Using the most universal in domestic and international displacement of reservoir oil formula
Surfactant be anion sulfoacid salt and metal carboxylate, followed by non-ionic and amphoteric ion type, application is least
It is cationic surface active agent.Anionic surfactant when being applied in combination as the displacement of reservoir oil, need with alkali compatible use,
Middle heavy alkylbenzene sulfonate must then can be with weak base compatibility, although the presence of alkali is really to mentioning with highly basic compatibility, petroleum sulfonate
Certain effect is played for recovery ratio, the heavy alkyl benzene alkali system as used in grand celebration can be improved from the point of view of current application
Recovery ratio about 20% or so, but use of the alkali in system can act on behalf of negative make to the treatment process of injection process and Produced Liquid
With, such as serious scale formation can be caused, the processing of injection and Produced Liquid to displacing fluid causes serious influence.Together
When some field tests in recent years show due to using alkali, may cause oil well fouling, capillary channel blocking, it is serious very
It is scrapped to may cause oil well, the reason is that alkali may generate insoluble substance with the mineral qualitative response in rock or water flooding.Together
When existing surfactant salt resistant character resistant to high temperatures is poor, oil displacement efficiency is low.
