Description

Tea saponin modification agent and its oil displacement agent of preparation
It is on December 01st, 2014, Application No. the applying date that the present invention, which is,：201410718901.4, entitled " stone The divisional application of the patent of invention of environment-friendly type salt tolerant high temperature resistance oil displacement agent of the oiling work containing biological surfactant ".
Technical field
The present invention relates to field of petroleum exploitation, and in particular to a kind of petrochemical industry uses the environment-friendly type containing biological surfactant resistance to Salt high temperature resistance oil displacement agent.
Background technology
Oil is important energy resources in production and living, as oil is constantly exploited, and oil field enters High water cut mostly, low Infiltration, viscous crude, high temperature, high salt mining period, remaining oil reservoir are distributed in the exploitation such as heterogeneous extremely strong carbonate rock fractured cave mostly The larger place of difficulty, effectively reliable exploitation can not have been carried out using traditional oil displacement agent.Although some scholars have developed Going out a series of novel surfactant is used for oil exploitation, but it is still present that usage amount is big, oil displacement agent can not degrade Problem.
The content of the invention
The environment-friendly type salt tolerant high temperature resistance containing biological surfactant is used to drive it is an object of the invention to provide a kind of petrochemical industry Finish, can improve oil displacement efficiency and sweep efficiency, increase recovery ratio, and usage amount is small, the degradation property after demulsification is excellent.
To achieve the above object, the present invention, which is adopted the following technical scheme that, is implemented：
A kind of environment-friendly type salt tolerant high temperature resistance oil displacement agent of petrochemical industry containing biological surfactant, its component includes 0.1~ Hay bacillus lipopeptid sodium, the tea saponin modification agent of 5~8 parts by weight, the water of 80~85 parts by weight of 1.2 parts by weight.
Further：
Its component also includes linear alkylbenzene sulfonate (LAS), the glycine betaine of 4~6 parts by weight of 4~6 parts by weight.
The structural formula of Tea Saponin is：
In order to which as stated, its structural formula just is reduced into MCOOH in the present invention；
Signified tea saponin modification agent is the composition of following structural formula in the present invention：
CH3CH2C(COOCM)3-n(CH2OH)n
Wherein：N is 0 or 1 or 2；It is preferred that n=3.
It is preferred to use the following two kinds scheme for above-mentioned tea saponin modification agent to produce：
The reaction principle of first scheme is：
Catalyst used can be toluene sulfonic acide, Anhydrous potassium carbonate, preferably from cerous sulfate/activated carbon solid-carrying type to first Benzene sulfonic acid is as catalyst, and the material ratio of reaction is 3.5:1, reaction temperature is 90~95 DEG C.
The reaction principle of alternative plan is：
MCOOH+SOCl2→MCOOCl+HCl+SO2
nMCOOCl+CH3CHC(CH2OH)3→CH3CH2C(COOCM)3-n(CH2OH)n+nHCl
In alternative plan, the material ratio of first stage reaction is 1.1:1,20~25 DEG C of reaction temperature, the hydroxyl of second stage three The addition of methylpropane is 1/3 (mole inventory) of thionyl chloride dosage in the first stage, reaction temperature is 40~ 45℃。
Certain those of ordinary skill in the art can choose corresponding material ratio and anti-according to reaction mechanism disclosed above Temperature is answered to obtain the production rate of optimal tea saponin modification thing.
Sodium bacillus subtilis lipopeptide is used as tertiary oil recovery surfactant, and profit is may be such that under extremely low concentration conditions Interfacial tension can also reach 10-3The mN/m orders of magnitude；The degradation property of hay bacillus lipopeptid sodium is excellent simultaneously, can natural decomposition into 4 Plant single amino acid；Tea Saponin is the byproduct that tea seed cake prepares feed removing, and it is directly discharged usually as sewage, Tea Saponin tool Have it is excellent emulsify, disperse, moistening, foam performance, HLB value reaches 16, but its dissolubility in water is limited, therefore in this hair Tea Saponin is modified in bright, improving the dissolubility of Tea Saponin and further lifting it reduces the energy of oil water interfacial tension Power, modified Tea Saponin and hay bacillus lipopeptid sodium compatibility are into efficient three oil displacement agents.
Furthermore it is also possible to the addition linear alkylbenzene sulfonate (LAS) of selectivity, glycine betaine, methyl glucamine, coconut oil The helper components such as fatty monoethanol amide, further to improve the sodium salt high temperature resistant property of oil displacement agent, it should be noted, however, that It is that the helper component of selected addition should be easy to natural degradation.Linear alkylbenzene sulfonate (LAS), the beet selected in the present invention Alkali, methyl glucamine, coconut oil fatty acid monoethanolamide are all the chemical constituents for being capable of rapid and natural degraded, it is ensured that driven The feature of environmental protection of finish.
Sodium bacillus subtilis lipopeptide, tea saponin modification thing and other helper components disclosed above is collocated with each other the drive being configured to Finish, 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 that the tea saponin modification extracted from tea seed cake is made, reduce the raw material of oil displacement agent into This, and after the crude oil demulsification taken, due to the characteristic of sodium bacillus subtilis lipopeptide, Tea Saponin, sodium bacillus subtilis lipopeptide can resolve into 4 kinds Single amino acid, Tea Saponin can be by microorganism natural decomposition, and the degradability of the oil displacement agent of separation is excellent, it is to avoid the oil displacement agent of separation It can not degrade and cause secondary pollution, play the effect of environmental protection.
The oil displacement agent of such scheme composition, 10 are can reach in less concentration-3The energy of mN/m oil/water interfacial tension Power, consumption 2 can be saved relative to the general oil displacement agent being made up of common weight alkyl sulfonate, glycine betaine and Gemini surface active agent More than times, oil displacement efficiency improves 15% or so.
