Description
Technical field
The present invention relates to the foam flooding oil preparation in a kind of oil exploitation.
Background technology
In order to improve petroleum drilling and mining rate, generally can select chemical oil displacement agent in oil recovery, wherein foam flooding oil preparation is one and important grinds
Study carefully direction.Chinese invention CN1093589 describes a kind of foam compsoite oil drive method, selects surfactant, alkali, polymer
Aqueous solution as oil displacement agent, wherein alkali 0.5%-1.5%, surfactant 0.05%-0.5%, polymer 0.05%-0.5%, all
For weight ratio, oil recovery factor 25%-30% can be improved.But this formula has selected alkali, easily cause oil reservoir and block, infiltration
Degradation problem under rate, and emulsification of crude oil is serious, and Produced Liquid profit is difficult to separate, and the refinery for downstream brings difficulty.Additionally existing
In the composition environmental protection all not that a lot of foam flooding oil preparationes selects, environment can be caused by the water that permeates the ground the biggest harm.
Summary of the invention
It is an object of the invention to provide a kind of foam flooding oil preparation.
For realizing above-mentioned goal of the invention, technical scheme is as follows:
A kind of foam flooding oil preparation, including the component of following weight portion:
Further, described foam flooding oil preparation includes the component of following weight portion:
Further, described foam flooding oil preparation includes the component of following weight portion:
Further, described foam flooding oil preparation includes the component of following weight portion:
Further, described foam flooding oil preparation includes the component of following weight portion:
A Alkylbenzensulfonate 40 parts
Surfactant B 10 parts
50 parts of E water,
Surfactant B therein can directly use buys the high-temp foaming agent inspiring confidence in Coase Petrotechnik Ltd. from Dongying City
FQ-1, is mainly composed of nonionic ethers and fluorocarbon surfactant mixture, directly can be buied by market.
The molecular structural formula of described Alkylbenzensulfonate is as follows:
R1、R2、R3For H, CH3、C2H5、C3H7、C4H9、C5H11、C6H13、C7H15Any one middle group, institute
State group and be linear chain structure.
The preferred R of described Alkylbenzensulfonate3-C4H9、R2-C7H15、R1-C7H15Straight chained alkyl.
It is arbitrary that described surfactant is selected from Brij 35 sodium sulfate or cocamido propyl betaine
Kind.
Brij 35 sodium sulfate molecular formula is: C12H25O(C2H4O)nSO4Na, the water of its 70% content conventional
Solution, is abbreviated as AES-2EO-70.
Cocamido propyl betaine, molecular formula is: C19H38N2O3.
The action principle of this foam flooding oil preparation is:
Expand microcosmic swept volume: during foam system displacement water drive residual oil, foam initially enters the macropore that resistance is little
Road, occupied by the foam that the interstitial space being originally occupied by the water constantly is injected.Resistance due to bubble is more than the resistance of liquid stream,
Follow-up displacing fluid can only be walked around bubble from the passage between bubble and rock and flow into pore throat interstitial space less, that do not occupied by bubble,
Foam is also into the hole occupied by follow-up displacing fluid and venturi subsequently, forces the latter to enter in less pore throat, this process
Make to remain in these water drives not yet sweep and fine pore in residual oil by displacement out.
Improve oil displacement efficiency: foam flooding has the mechanism of oil displacement that water alternating gas injection is same, but its relatively water alternating gas injection has more
Strong fluidity control ability, higher washing oil ability, after bubble burst, still there is the micro scale sweep mechanism of water alternating gas injection.
Expand macroscopic view swept volume: foam flooding all has considerable influence to raising vertical sweep efficiency and plane sweep efficiency, increase height
The flow resistance of infiltration fluid-channeling channel, reduces interlayer (or in layer) interference, adjusts relation in interlayer or layer, improve the ripple of oil reservoir
And volume
The invention has the beneficial effects as follows:
1. foam stability is good, 50 DEG C of half foam life periods up to 400min, foam volume 330mL,
2. there is high surface, need not outer adding assistant, it is possible to oil water interfacial tension is greatly lowered,
3. there is strong washing oil ability, change wettability of rock surface,
4. properties of product are stable, and good water solubility, good with various recovered water compatibilities, resisting high temperature, high salt, 220 ° are not decomposed.
