Abstract
The invention relates to a temperature-resisting anti-salt surfactant compounding system and a compounding method thereof. The compounding system is prepared from, by weight, 55-70 parts of main agents, 15-30 parts of anionic surfactants, 5-15 parts of additives, 2-10 parts of sacrificial agents and 5-10 parts of deionized water; the general molecular formula of the main agents is CnH(2n+1)COO(CH2CH2O)mCH2CH2SO3M, wherein M represents alkali metal sodium or potassium, n represents any one integer from 12 to 18, and m represents any one integer from 3 to 7. The compounding system serves as an oil-displacing agent to be used for tertiary oil recovery and has the advantages that the oil-displacing agent is verified through a homogeneous core oil-displacing test under the high-temperature and high-mineralization-degree conditions, and the crude oil recovery ratio can be increased by more than 30 percent.
Description
Technical field
The invention belongs to oil recovery field, be specifically related to a kind of temperature resistant antisalt surfactant compound system and preparation method thereof.
Background technology
China's main oilfield is through once with after secondary recovery entering high water-cut stage, crude production rate declines year by year, for improving oil recovery factor, develop remaining reserves to greatest extent, the use binary of tensio-active agent, the tertiary oil recovery of ternary composite driving technology have played very important effect in guarantee oilfield stable production high yield.
Because the environment of subsurface deposit is very complicated, under many oil reservoirs are in " three is high " condition of high temperature, high salinity, high contents of calcium and magnesium ion, this just requires that tensio-active agent will have good heatproof, anti-salt, anti-high valence ion ability.At present for the tensio-active agent of tertiary oil recovery, much in the underground water of high salinity, high contents of calcium and magnesium ion, easily there is layering or Precipitation, simultaneously chemical structure malleable, compound system poor stability under the high temperature conditions, in oil displacement process, easily produce serious chromatographic separation, cause oil displacement efficiency poor.So tertiary oil recovery is in the urgent need to the oil-displacing agent of development of new, make it both environmentally friendly, readily biodegradable significantly can reduce oil water interfacial tension when not adding alkali again, and then environmental protection, improves the recovery ratio of crude oil economically.
Summary of the invention
The object of the present invention is to provide a kind of temperature resistant antisalt surfactant compound system and preparation method thereof, not containing the aromatic nucleus such as benzene, naphthalene in formula system, there is the advantages such as temperature resistant antisalt, environmental protection, readily biodegradable, inexpensive, high interfacial activity, and low price.
The technical solution adopted for the present invention to solve the technical problems is: a kind of temperature resistant antisalt surfactant compound system, is made up of the component of following weight proportion:
Particularly, described host general molecular formula is C
nh
2n+1cOO (CH
2cH

mcH
2cH
2sO
3m, in formula, M is alkali metallic sodium or potassium, and n is any one integer in 12-18, and m is any one integer in 3-7.
Particularly, described anion surfactant is one or more in alkylbenzene sulfonate, sulfonated petro-leum, petroleum carboxylate, succsinic acid sulfonate, alkylphenol polyoxyethylene sodium sulfonate and sodium carboxymethylcellulose pyce.
Particularly, described additive is one or more in alcohols, ethers, salt analog assistant, and alcohol analog assistant is amylalcohol, ethylene glycol, Virahol; Ethers auxiliary agent is ethylene glycol monobutyl ether, the only butyl ether of Diethylene Glycol; Salt analog assistant is sodium-chlor, Repone K.
Particularly, described sacrifice agent is one or more in the complex compound of sodium lignosulfonate, chrome lignosulfonate.
Above-mentioned temperature resistant antisalt surfactant compound system, preparation method is performed as follows:
1) under 35 DEG C of condition of normal pressure, by host, anion surfactant, 50% deionized water join in reactor, fully stir 1.5-3h;
2) by residue 50% deionized water, additive, sacrifice agent mixing and stirring, 1-2h is stirred;
3) by step 2) stir after material be transferred to step 1) material in, stir and namely obtain compound product in 0.5-2.5 hour.
In actual applications, due to the difference of oil field block, reservoir condition is inconsistent, and the composition of crude oil, underground water, clay mineral is different, therefore just various combination, different ratios can be selected to carry out for different reservoir conditions composite, to reach best oil displacement efficiency.
Compound system of the present invention is used for tertiary oil recovery as oil-displacing agent, has the following advantages: oil-displacing agent of the present invention, under high temperature, high salinity condition, confirms through the test of homogeneous core flooding test, can improve oil recovery factor more than 30%.
Oil-displacing agent of the present invention is at Shengli Oil Field Cheng Bei mono-district Ng
4-5profit system under, when total mass concentration is 0.1%-0.6%, ultra low interfacial tension value can be reached; System is deoxygenation nitrogen envelope under reservoir temperature, still can reach ultra low interfacial tension value, have good thermostability through 60 days.
In compound system, host is sulfonate, is particularly applied to Shengli Oil Field, after composite with the anion surfactant such as sulfonated petro-leum, not easily " chromatographic separation " occurs in the earth formation.The most general using method in present oil field is undertaken composite by nonionic and anion surfactant, but this flooding system easily occurs serious " chromatographic separation " in the earth formation, thus cannot realize its optimal design.
