Description
Technical field
The present invention relates to a kind of carbon dioxide foam systems that with the addition of hydrophilic nano particle and preparation method thereof, belong to
Oil-Gas Field Development Engineering technical field.
Background technology
The burning of fossil fuel will produce substantial amounts of carbon dioxide, and the random discharge of carbon dioxide will cause greenhouse
Effect, endangers the weather safety of the mankind.With the increasingly raising that people require for carbon dioxide discharge-reduction, carbon dioxide buries
Deposit with having obtained more and more concerns using technology.
Carbon dioxide can interact with the crude oil in stratum, and playing reduces viscosity of crude, improves crude oil elasticity
The effect of energy, and nitrogen, air and methane gas are compared, carbon dioxide is low with the miscible pressure of crude oil, is led in oil field development
It is a kind of ideal oil displacement agent in domain.Therefore, during carbon dioxide being used crude oil production, it can both play and subtract
The effect of row, and the recovery ratio of crude oil can be improved, there is good social benefit and economic benefit.And since carbon dioxide is on ground
Viscosity is low under the conditions of layer, and big with the mobility ratio of crude oil, many stratum have heterogeneous feature in addition, therefore in oil displacement process
Gas channeling phenomenon easily occurs, causes the sweep efficiency to formation crude oil low, so as to reduce the oil displacement efficiency of carbon dioxide.Foam
The mobility of gas can be reduced, and there is selective shut-off to hypertonic stratum, can preferably solve problem above.Often
The carbon dioxide foaming foaming agent main component of rule is surfactant, and the heatproof of conventional surfactants, salt resistant character compared with
Difference, high temperature and high salinity condition stability inferior in the earth formation are poor, it is impossible to form the higher carbon dioxide foaming of quality.Liu
It is firelight or sunlight, Hua Qingchang oil reservoirs CO2Drive foam system evaluation study, Xi'an Petroleum University, 2012, the paper studies temperature, mineralising
The influences of the factor to the carbon dioxide foaming stability produced by surfactant such as degree.The result shows that surfactant ZY-1
The carbon dioxide foaming of generation half-life period when sodium chloride (NaCl) concentration is 1% is 9.17min, is partly declined when temperature is 60 DEG C
Phase is only 6.67min.
For this problem, there is researcher to propose to improve carbon dioxide foaming on ground by adding hydrophobic nano particle
Stability in layer.Li Zhaomin etc., SiO2Nano particle is with SDS to CO2The synergistic stability effect of foam, Northeast Petroleum University are learned
Report, in June, 2014, the 3rd phase, the document have studied hydrophobic type nano SiO 2 particle with anionic surfactant to two
Aoxidize the stablizing effect of carbon foam.The result shows that in SiO2Mass concentration is the dioxy obtained when 1.5%, SDS concentration is 0.25
Change carbon foam half-life period can reach 37.2min.However, hydrophobic nano particle cost is higher, and since hydrophobicity is strong, in water
In disperse that difficulty is big, and the foaming agent solution dispersion stabilization being prepared into is poor, therefore may will face in Oil Field application
Many construction technology problems.
Single hydrophilic nano particle dispersion can not play the role of stable foam, but since its surface can be by part
SURFACTANT ADSORPTION and produce synergistic effect, therefore with part surface activating agent suitably proportioning under, hydrophilic nano
Grain can also play the role of improving carbon dioxide foaming heatproof, salt resistant character.Further, since hydrophilic nano particle cost is remote
Less than hydrophobic nano particle, and it is easy to disperse in water, therefore, practical value is higher in Oil Field, has preferable
Application prospect.

Part, 0.2-0.8 parts of carbon dioxide, 100 parts of water.
According to the present invention, the preparation method of the carbon dioxide foam systems of above-mentioned addition hydrophilic nano particle, including step
It is rapid as follows：
(1) hydrophilic nano particle is added to the water and stirred evenly according to proportioning, then sequentially add nonionic table
Face activating agent and inorganic salts, ultrasonic disperse 3-5min；
(2) carbon dioxide 2-5min is continually fed into the system obtained to step (1), then with 7000-9000r/min's
Rotating speed stirs 3-5min min, to obtain the final product.
Hydrophilic nano SiO 2 particle of the present invention, can market buy, can be also prepared by the prior art.
The principle of the present invention：
Hydrophilic nano particle is predominantly located in liquid phase since hydrophilicity is too strong, it is impossible to gas-liquid interface is adsorbed onto, because
And stable foam can not be played the role of.The polar group of lauryl alcohol polyethylene glycol oxide polyethenoxy ether and the silicon of nano grain surface
Hydroxyl can be formed by hydrogen bond action and adsorbed so that and nano particle hydrophobic performance strengthens, and can be adsorbed onto on gas-liquid interface, so that
Stabilization is played to foam.And when laruyl alcohol polyoxyethylene poly-oxygen propylene aether excessive concentration, under the action of Van der Waals force,
Double-deck absorption can be formed between surfactant in particle surface so that particle hydrophilicity strengthens, and loses the effect of foam stabilizing.
Therefore, only under suitable proportioning, the two could play carbon dioxide foaming the stable effect of collaboration.
Compared to nitrogen and air, the solubility of carbon dioxide in water is larger, and diffusion velocity is very fast in the liquid phase, exacerbates
The disproportionation of carbon dioxide foaming, causes carbon dioxide foaming more unstable compared to nitrogen and air foam.And nanometer
Grain can reduce contact of the carbon dioxide with liquid phase when it is adsorbed onto on gas-liquid interface since size is much larger than surfactant
Area, so as to reduce disproportionation, enhances the stability of foam.In addition, the addition of nano particle can increase liquid phase
Viscosity, so as to slow down the drain age velocity of foam.And the addition of appropriate sodium chloride can reduce the surface potential of nano particle, subtract
Small intergranular electrostatic repulsion so that arrangement of the particle on gas-liquid interface is even closer, further increases carbon dioxide
The stability of foam.
The excellent technique effect of the present invention：
1st, by the compounding with nonionic surfactant, make can not the hydrophilic nano particle of independent foam stabilizing obtain foam stabilizing
Performance.Diffusion rate is very fast in the liquid phase for carbon dioxide, therefore the disproportionation of carbon dioxide foaming is formed compared to other gases
Foam become apparent, and since nano particle is larger compared to the size of surfactant, when it is adsorbed in gas-liquid interface
The contact area of carbon dioxide and liquid phase can be reduced, the disproportionation of foam is reduced, greatly improve carbon dioxide foaming
Stability.
2nd, hydrophilic nano particle has the characteristics that solid particle, and heatproof, salt resistant character are stronger, carbon dioxide foaming is existed
High temperature, high salt formation condition under still there is preferable stability, play the advantage of its displacement of reservoir oil.
3rd, hydrophilic nano particle is smaller compared to formation pore throat size, can freely migrate, stratum will not be damaged；
In addition, hydrophilic nano particle is easy to disperse in water, foaming agent system preparation method and site construction technology are simple, and compare
Hydrophobic nanoparticles are of low cost, it is easier to are promoted and applied in oil field.
