The invention discloses an environment-friendly salt-resistant high-temperature-resistant oil displacement agent containing biological surfactant and used in the petrochemical industry. The oil displacement agent comprises, by weight, 0.1 to 1.2 parts of sodium surfactin, 5 to 8 parts of tea saponin modifier and 80 to 85 parts of water. According to the invention, the sodium surfactin, the tea saponin modifier and other auxiliary components are combined for preparation of the oil displacement agent; the oil displacement agent can be used for exploitation of high-water-content, low-permeability, thickened, high-temperature and high-salt oil reservoirs and can improve oil displacement efficiency, sweep efficiency and recovery efficiency; the tea saponin modifier is prepared from tea saponin extracted from tea seed meal, so cost for the raw materials of the oil displacement agent is reduced; moreover, because of the characteristics of the sodium surfactin and the tea saponin, the sodium surfactin can be decomposed into 4 single amino acids and the tea saponin can be naturally decomposed by microorganisms after demulsification of crude oil; and the separated oil displacement has excellent degradation performance, so secondary pollution caused by incapable degradation of the separated oil displacement is avoided and environmental protection effects are obtained.
Description
Technical field
The present invention relates to field of petroleum exploitation, be specifically related to the environment-friendly type salt tolerant high temperature resistance oil-displacing agent of a kind of petrochemical complex containing biological surfactant.
Background technology
Oil is Energy resources important in productive life, along with oil is constantly exploited, oil field enters High water cut, hyposmosis, viscous crude, high temperature, high salt mining period mostly, residue oil reservoir is distributed in the larger place of the exploitation difficulty such as the extremely strong carbonate rock fractured cave of heterogeneous body mostly, uses traditional oil-displacing agent cannot carry out exploitation effectively reliably.Although some scholar has developed a series of novel surfactant for oil production, still there is the problems such as usage quantity is large, oil-displacing agent cannot be degraded in it.
Summary of the invention
The object of the present invention is to provide a kind of petrochemical complex with containing the environment-friendly type salt tolerant high temperature resistance oil-displacing agent of biological surfactant, oil displacement efficiency and sweep efficiency can be improved, increase recovery ratio, and usage quantity is little, degradation property after breakdown of emulsion is excellent.
For achieving the above object, the present invention adopts following technical scheme to implement:
Petrochemical complex is with containing the environment-friendly type salt tolerant high temperature resistance oil-displacing agent of biological surfactant, and its component comprises the Bacillus subtilus lipopeptid sodium of 0.1 ~ 1.2 weight part, the tea saponin modification agent of 5 ~ 8 weight parts, the water of 80 ~ 85 weight parts.
Further:
Its component also comprises the linear alkylbenzene sulfonate of 4 ~ 6 weight parts, the trimethyl-glycine of 4 ~ 6 weight parts.
The structural formula of tea saponin is:
In order to just as statement, in the present invention, its structural formula is reduced to MCOOH;
In the present invention, the tea saponin modification agent of indication is the composition of following structural formula:
CH
3CH
2C(COOCM)
3-n(CH
2OH)
n
Wherein: n is 0 or 1 or 2; Preferred n=3.
The following two kinds scheme is preferably adopted to produce for above-mentioned tea saponin modification agent:
The reaction principle of first scheme is:
Catalyzer used can be toluene sulfonic acide, Anhydrous potassium carbonate, and preferably select cerous sulfate/gac solid-carrying type tosic acid as catalyzer, the material ratio of reaction is 3.5:1, and temperature of reaction is 90 ~ 95 DEG C.
The reaction principle of alternative plan is:
MCOOH+SOCl
2→MCOOCl+HCl+SO

nMCOOCl+CH
3CH C(CH
2OH)
3→CH
3CH
2C(COOCM)
3-n(CH
2OH)
n+nHCl
In alternative plan, the first stage material ratio of reaction is 1.1:1, temperature of reaction is 20 ~ 25 DEG C, and the addition of subordinate phase TriMethylolPropane(TMP) is 1/3 (mole inventory) of thionyl chloride dosage in the first stage, and temperature of reaction is 40 ~ 45 DEG C.
Certain those of ordinary skill in the art can according to above-mentioned disclosed reaction mechanism, chooses corresponding material ratio and temperature of reaction to obtain the production rate of optimum tea saponin modification thing.
Sodium bacillus subtilis lipopeptide uses as tertiary oil recovery tensio-active agent, and oil water interfacial tension can be made under extremely low concentration conditions also to reach 10
-3the mN/m order of magnitude; The degradation property of Bacillus subtilus lipopeptid sodium is excellent simultaneously, natural decomposition can become 4 kinds of single amino acid; Tea saponin is the byproduct that the tea dregs of rice are prepared feed and removed, it directly discharges usually used as sewage, tea saponin has excellent emulsification, dispersion, moistening, foam performance, HLB value reaches 16, but its solvability in water is limited, therefore carry out modification to tea saponin in the present invention, improve the solvability of tea saponin and promote the ability that it reduces oil water interfacial tension further, modified tea saponin becomes efficient three oil-displacing agents with Bacillus subtilus lipopeptid sodium compatibility.
In addition, can also optionally add the auxiliary components such as linear alkylbenzene sulfonate, trimethyl-glycine, methyl glucamine, coconut oil fatty acid monoethanolamide, to improve the sodium salt high temperature resistant property of oil-displacing agent further, but, it should be noted that the selected auxiliary component added should be easy to natural degradation.The linear alkylbenzene sulfonate selected in the present invention, trimethyl-glycine, methyl glucamine, coconut oil fatty acid monoethanolamide are all can the chemical composition of rapid and natural degraded, ensure the feature of environmental protection of oil-displacing agent.
Above-mentioned disclosed sodium bacillus subtilis lipopeptide, tea saponin modification thing and other auxiliary component are arranged in pairs or groups the oil-displacing agent be mixed with mutually, it can be used for High water cut, hyposmosis, viscous crude, high temperature, the exploitation of high salt form oil reservoir, improve oil displacement efficiency and sweep efficiency, increase recovery ratio, and tea saponin modification agent is the tea saponin modification extracted from the tea dregs of rice to be obtained, reduce the raw materials cost of oil-displacing agent, and after the crude oil demulsification taked, due to sodium bacillus subtilis lipopeptide, the characteristic of tea saponin, sodium bacillus subtilis lipopeptide can resolve into 4 kinds of single amino acid, tea saponin can by microorganism natural decomposition, the degradation property of the oil-displacing agent be separated is excellent, avoid the oil-displacing agent be separated cannot degrade and cause secondary pollution, play the effect of environmental protection.
The oil-displacing agent of such scheme composition, can reach 10 when less concentration
-3the ability of the oil/water interfacial tension of mN/m, can save consumption more than 2 times relative to the general oil-displacing agent be made up of common heavy alkyl sulfonate, trimethyl-glycine and Gemini surface active agent, and oil displacement efficiency improves about 15%.
