Description
Technical field
The present invention relates to the foam flooding finish in a kind of oil production.
Background technology
In order to improve the petroleum drilling and mining rate, in oil recovery, can select chemical oil displacement agent for use usually, wherein the foam flooding finish is a research direction.China invention CN1093589 has put down in writing a kind of foam compsoite oil drive method; The aqueous solution of selecting tensio-active agent, alkali, polymkeric substance for use is as oil-displacing agent; Alkali 0.5%-1.5% wherein, tensio-active agent 0.05%-0.5%, polymkeric substance 0.05%-0.5%; Be weight ratio, can improve oil recovery factor 25%-30%.But this prescription has been selected alkali for use, causes oil reservoir to block easily, problems such as permeability plugging, and emulsification of crude oil is serious, and extraction liquid profit is difficult to separate, for the refinery in downstream brings difficulty.The all not enough environmental protection of the composition that now a lot of in addition foam flooding finishes is selected can cause very big harm to environment in the water that permeates the ground.
Summary of the invention
The purpose of this invention is to provide a kind of foam flooding finish.
For realizing above-mentioned goal of the invention, technical scheme of the present invention is following:
A kind of foam flooding finish comprises the component of following weight part:
Further, said foam flooding finish comprises the component of following weight part:

Said tensio-active agent is selected from any in dodecyl alcohol polyoxyethylene ether sodium sulfate or the AMONYL 380LC.
Dodecyl alcohol polyoxyethylene ether sodium sulfate molecular formula is: C

AMONYL 380LC, molecular formula is: C19H38N2O3.
The action principle of this foam flooding finish is:
Enlarge the microcosmic swept volume: in the process of foam system displacement water drive irreducible oil, foam is the little macropore of intake resistance at first, and the foam that the pore space quilt that was occupied by water originally constantly injects is occupied.Because the resistance of bubble is greater than the resistance of flow; Follow-up displacing fluid can only be walked around bubble flow from the passage between bubble and rock and go into pore throat pore space less, that do not occupied by bubble; Foam also enters into hole and the venturi that is occupied by follow-up displacing fluid subsequently; Force the latter to get in the littler pore throat, this process make remain in that these water drives are not swept as yet and the fine porosity in irreducible oil come out by displacement.
Improve oil displacement efficiency: foam flooding has aqueous vapor and alternately injects same oil-displacement mechanism, but it alternately injects than aqueous vapor and have stronger mobility control ability, and stronger washing oil ability after the bubble burst, still has the microcosmic oil drive mechanism that aqueous vapor is alternately injected.
Enlarge macroscopical swept volume: foam flooding all has considerable influence to improving vertical sweep efficiency and plane wave and efficient, increases the resistance to flow of height infiltration fluid-channeling channel, reduces interlayer (or in layer) and disturbs, and adjusts relation in interlayer or the layer, improves the swept volume of oil reservoir
The invention has the beneficial effects as follows:
1. froth stability is good, and 50 ℃ of half foam life periods reach 400min, lather volume 330mL,
2. have high surface, need not outer adding assistant, just can reduce oil water interfacial tension significantly,
3. have strong washing oil ability, change the rock surface wettability,
4. product performance are stable, and good water solubility is good with various recovered water compatiblenesies, resisting high temperature, high salt, and 220 ° are not decomposed.
