Description
Technical field
The present invention relates to petroleum industry heavy crude reservoir to block up conditioning technology, the compound stifled tune liquid of more particularly to a kind of three-phase froth and system
Make method and application.
Background technology
Foam is because have the characteristics of Jia Min synergistic effects and high apparent viscosity, therefore can effectively block high permeability zone or macropore
Road, and with injection pressure rise, can gradually feed through in middle low permeability formation, effectively improve sweep efficiency.Simultaneously as foam flooding
System has the closure feature that reducing viscosity by emulsifying effect and water blockoff do not block up oil, therefore is widely used in oil reservoir and blocks up conditioning technology and chemical flooding
Improve the fields such as recovery ratio.But conventional two-phase foam system intensity is general weaker and under formation conditions（Especially high temperature bar
Under part）It is unstable, easily rupture, therefore block the term of validity can substantially shorten.For Edge water energy is big, steam driving exploitation is all
The heavy crude reservoir of phase length, if wanting to obtain comparatively ideal oil displacement efficiency, it is necessary to the blocking agent system grown using stabilization time.Research hair
Existing, the stability of three-phase froth system is typically up to 10~30 times of corresponding two-phase foam.
Three-phase froth is dispersion mixture that is mutually foamed by solid, liquid, gas and being formed.The forming process of three-phase froth
Mainly：Due to graviational interaction between base fluid motion and surface, solid particle is gentle to bubble out the chance now to contact with each other；Due to
Solid particle is approached to bubble, and the common water layer between solid particle and bubble is gradually squeezed away from crack, until solid particle
The hydrated sheath on surface and the hydrated sheath of bubble surface contact with each other；It is additional can be under effect, the gradual thinning formation water of hydrated sheath
Change film.Due to the unstability of hydration shell, solid particle and bubble further approach, and free energy reduces, and aquation film thickness is spontaneous
Thinning, solid particle is sent to bubble certainly and approached；Hydration shell is further thinning until rupture, solid particle and bubble contact are simultaneously attached
And three-phase froth is formed in walls.Solid phase particles carry out wedge-shaped arrangement, the borderline rows of bubble Plateau in bubble film
Liquid speed rate can be obviously reduced, and the obstacle mutually merged as bubble, increase the resistance of flow of fluid in liquid film, improve liquid film and glue
Elasticity and intensity, extend half foam life period.Solid phase particles can be accumulated in pore constriction after bubble burst, form machinery envelope
It is stifled.Because having the Jamin effect of foam and the mechanical blockage effect of particle concurrently, therefore three-phase froth system has stifled tonality well
Energy.

Formation fracture pressure, wellhead manifold rated operating pressure within.
The compound stifled tune liquid of three-phase froth of the present invention, raw materials used operation principle are as follows：Ultra-fine clay particle fineness compared with
Small, water imbibition is strong, and being dispersed in water has higher viscosity, and adhesive force is good, is main in the compound stifled tune liquid system of the three-phase froth
The solid-phase foam stabilizer wanted.When clay is impregnated in water, the kaolinite in clay can disperse the false hexahedron to form sheet
Particle, the surface and edge of particle can carry different electric charges, and in the presence of electric charge, each intergranular side mutually attracts with face,
Form scaffolding structure.After superfine cement adds, cement hydration reaction at initial stage is strong, simultaneously because cement granules are more than clay
Grain, and there is positive charge in cement particle surface, when cement granules and the false hexagonal flake clay particle in clay slurry meet,
Under different charge effects, the clay particle of sheet can be adsorbed on cement particle surface, the clay formed centered on cement
Cement spherical structure, increase system endoparticle particle diameter, strengthen the plugging strength of particle tamper.It is less when running into pore throat diameter
During layer, the clay cement granules in stifled tune system are easily accumulated in end face, three-phase froth system is separated into solid phase particles
And gas-liquid mixed phase.Due to containing hydrolyzed polyacrylamide, water soluble phenol resin crosslinking agent and organic chrome cross linker in system, three
Person can crosslink reaction under the conditions of the certain temperature containing gas and form gel foam, improve foam stability again.Have
Machine chromium cross linker and phenolic aldehyde the cross-linking system crosslinking time at 150 DEG C are about 90 min, are had under higher than 90 DEG C high temperature longer
Ageing time.Simultaneously as heat scatters and disappears and the heat-insulated of solid particle waits effect, the vapor (steam) temperature into deep has dropped
Low, the gel foam of formation is not easy to be destroyed.Lauryl sodium sulfate has preferable frothing capacity, with the presence of foam stabilizer
In the case of, the foam that the foaming agent foam is formed has higher stability, therefore at high temperature, high foaming agent also with compared with
Good performance.Sodium metasilicate is also known as waterglass, and it is good mud dispersant and structure-forming agent；Added in clay cement grout
During a certain amount of waterglass, the hydration capability and stability of clay particle improve, and waterglass can also be in hydrated cementitious mistake
Hydrated calcium silicate gel is formed in journey.The addition of waterglass can effectively adjust the speed of clay cement solidification, and can be in certain journey
Increase the impermeability of particle stack on degree.
The beneficial effects of the invention are as follows：The present invention be directed to current thick oil steam drive oil reservoir regular-type foam to drive effective period
Short, the problems such as action effect is poor and develop, stability is high, high temperature resistant, and heavy crude reservoir deep profile correction is driven suitable for high-temperature steam.This
Invention is by the foam profile to be succeeded in field practice in recent years, polymer transfer drive, inorganic particle transfer drive and surfactant
Transfer drive combines, and is made by the mechanical blockage of Jamin effect and inorganic particle blocking agent that foam is produced in earth formation deep
With realizing the plugging and profile con-trol in oil well oil reservoir deep；And the gas being passed through has supplement stratum energy, reduces viscosity of crude
Effect；Polymer has viscoplasticity simultaneously；Surfactant can effectively change the wetability of formation rock again, emulsified crude oil,
Sweep area and displacement efficiency are increased substantially, while steam injection profile is improved, realizes the purpose of steady output of oilwell synergy.
