Abstract
The invention discloses more ethoxylated oil acid esters multi-element compounds of the double perfluoro decyl silicon of a kind of methyl and the preparation method and application thereof, which is combined by perfluoro decane, two silicon fluoride of monomethyl, ethylene oxide and oleic acid；Preparation method includes being warming up to 150~170 DEG C of addition ethylene oxide, oleic acid being added after reaction, finally adjusts pH to 7~8 perfluoro decane and monomethyl difluoro silane mixture, acidification.The multi-element compounds of the present invention are applied to carry out foam flooding in oil field.The multi-element compounds of the present invention can not only simply and efficiently blister, and foam stabilizing effect is good, and chromatographic isolation will not occur when can migrate in the earth formation, and especially foam flooding effect is good in hypotonic, water-sensitive oil field；Preparation method is simple simultaneously, and operability is strong, at low cost.
Description
Technical field
The invention belongs to foam flooding finish field more particularly to a kind of more ethyoxyl-oleic acid of the bis- perfluoro decyl silicon-of methyl-
Ester multi-element compounds and the preparation method and application thereof.
Background technology
The exploitation that aerated fluid is applied to oil field at home and abroad has more than 40 years history, aerated fluid the conventional displacement of reservoir oil,
Transfer drive, steam bubble drive, steam bubble handle up, cyclic steam foam flooding, the water pumping gas production of aqueous gas well, sand-flushing, drilling well,
All various aspects in the oil-gas field developments such as profile control, water blockoff, acidification, well cementing of cement and pressure break are applied, and are achieved willing
Fixed effect.Largely practice have shown that, foam flooding is the important means for protecting oil reservoir, preventing oil layer pollution, improving oil and gas production.
As the degree of recognition of foam technology is continuously improved in people, foam flooding means and foam flooding finish will become tertiary oil recovery
One of leading technology.There are a large amount of hypotonic water-sensitive oil fields in oil field, the big multichannel of the oil field stratum is narrow, permeability pole
Low, oil reservoir is migrated difficulty in the earth formation, and it is mostly the water-sensitive formations such as montmorillonite that stratum, which is constituted, and water-swellable will be originally narrow
Channel block causes oil extraction operation that can not carry out.Therefore, conventional water drive or water base foam can not be taken to drive the oil reservoir
Oil.
The oil-based foam displacement of reservoir oil is the effective means to solve the above problems.Using oily (usually using diesel oil or mineral oil) as continuously
The foam flooding finish of phase is referred to as oil-based foam oil displacement agent.Compared with water base foam oil displacement agent, oil-based foam oil displacement agent it is main
Feature is energy high temperature resistance, has very strong inhibition and salt resistance, resistant to pollution ability, lubricity is good, and can be effectively prevented from water drive
Caused by the stratum such as montmorillonite expansion passage the problem of, mitigate the damage to oil-gas Layer.But oil phase compares the surface of water phase
Can be extremely low, formation of foam is difficult, and is not easy to stablize, and conventional blister agent can not form oil-based foam, seriously affect oil-based foam
The development of oil displacement agent.Currently, oil-based foam oil displacement agent is mainly made of oil, water, foaming agent, foam stabilizer, emulsifier etc..System with
Water is dispersed phase, and using oil as continuous media, the materials such as addition emulsifier, foaming agent, foam stabilizer are formed by similar oils property
Emulsion foam system, also known as inverse emulsification foam flooding finish, grease volume ratio is in (50~80):(50~20) left and right.So
And with the necessary each component synergistic effect of conventional oil base foam flooding agent that emulsifier, foaming agent, foam stabilizer form, shape can be played
The purpose of oil displacement efficiency is realized at oil-based foam.Due to its in chemical constitution, functional group and polarity there are larger difference,
Serious chromatographic isolation can occur when migrating in stratum, the different location in stratum is respectively at so as to cause each component, it can not
Synergy embodies, and in turn results in oil-based foam and cannot achieve oil displacement efficiency.O ' Neil et al. have studied a kind of oil-based foam stream
Body, the oil-based foam fluid include mainly liquid control, Nephew class foaming agent, Pity vinegars, iron or lead crosslinking agent, gas etc.；Wherein liquid
It can be diesel oil, the other aliphatic hydrocarbons of kerosene person that state, which is dazzled,；Foaming agent selects fluorinated surfactant.Specific steps include：By diesel oil,
1.0%HF-2 (fiuorinated acrylic copolymer resin), 0.15%HG-2 (phosphate fat) and 0.15%HX-2 (iron adhesive) are mixed
It closes, using whisking at a high speed after device whisks 2min, gas release 47%, half-life period is more than 1h.Oil base bubble has been carried out in heart-to-heart talk et al.
The foam stabilizer DRI- of 0.1% foaming agent DRI-YF-1 and 2% is added in foam drilling fluid technical research in 100ml diesel oil
YW-1 is the chief component of oil-based foam drilling fluid, is evaluated foam volume, half-life period, rheological characteristic, as a result
Show that foam volume reaches 500ml, half-life period 630s, half-life period and foam volume reach the more excellent level in the world.But
It is that the composite request that above two oil base oil displacement agent can not meet foaming and foam stabilizing simultaneously (usually foams 300%, foam stabilizing
More than 1h).Therefore, how to reach the relative equilibrium of the two, while meeting above-mentioned requirements, have become the most important thing of research.
In addition, above-mentioned oil displacement agent is mostly mix reagent, migration in the earth formation can generate migration because of molecular results and polar difference
The difference of speed leads to chromatographic isolation phenomenon, and each component synergistic effect is caused to weaken, even lose.
In conclusion existing, there is an urgent need for one kind simply and efficiently to blister, and foam stabilizing effect is good, more particularly in the earth formation
The oil-based foam oil displacement agent that chromatographic isolation will not occur when migration, to improve hypotonic, water-sensitive oil reservoir oil recovery effect.

Alkane (ethyoxyl) is linked in a molecule compound that comes from different backgrounds and possess different abilities, and it imitates the blistering of perfluoro decane with high-flexibility
Fruit has certain facilitation.Preferably, n can be 10~18 in the multi-element compounds.
The method that the present invention prepares the more ethyoxyls of the bis- perfluoro decyl silicon-of methyl-- oleate multi-element compounds, including it is as follows
Step：By perfluoro decane and monomethyl difluoro silane mixture, acidification is warming up to 150~170 DEG C of addition ethylene oxide, after reaction
Oleic acid is added, finally adjusts pH to 7~8.
Furtherly, the molar ratio of perfluoro decane and two silicon fluoride of monomethyl can be 1 in the preparation:0.25~1.5.Perfluor
The molar ratio of decane and ethylene oxide can be 1:2.5~20.The molar ratio of perfluoro decane and oleic acid can be 1:0.25~1.2.
Furtherly, in the preparation, two silicon fluoride of perfluoro decane Yu monomethyl of addition is under the conditions of 50~70 DEG C
React 1~2h.1~2h is reacted after adding ethylene oxide.1.5~2h is reacted after adding oleic acid.
The more ethyoxyls of the bis- perfluoro decyl silicon-of methyl-- oleate multi-element compounds answering in the displacement of reservoir oil of oil field of the present invention
With.
Advantageous effect：Compared with prior art, remarkable advantage of the invention is：The multi-element compounds can not only it is simple,
It efficiently blisters, and foam stabilizing effect is good, chromatographic isolation will not occur when can migrate in the earth formation, be more suitable for hypotonic, water-sensitive
Foam flooding finish in oil field, oil recovery effect is good, particularly with medium oil content (oil content 70-80%), high wax foam system
Using effect protrude；Preparation method is simple simultaneously, and operability is strong, at low cost.
