Abstract
A provided oil displacement agent is prepared by compounding the following compositions: a) petroleum sulfonates accounting for 30%-70% of the total mass; b) a surfactant auxiliary agent accounting for 20%-30% of the total mass; c) a surfactant synergist accounting for 5%-15% of the total mass; and d) a surfactant solubilizer accounting for 3%-10% of the total mass. The beneficial effects comprise that the oil displacement agent is not added with alkalis, the production process does not pollute environment, the usage amount is 0.4%-0.6%, and the oil displacement agent is small in usage amount and low in cost.
Description
Technical field
The present invention relates to the chemical assistant field in tertiary oil recovery, especially relate to a kind of oil-displacing agent.
Background technology
The rational exploitation and utilization of petroleum-based energy has caused people's very big attention.Because first and second of routine total tar productivity of recovering the oil is not very high, generally only can reach 20%～40%, be up to 50%, also have 50%～80% crude oil to fail extraction.Therefore the in the situation that of being becoming tight in energy day, improving tar productivity has become the key subjects of oil production research, and tertiary oil recovery is a kind of method that especially effectively improves tar productivity.
At present, tertiary oil recovery research obtains people's generally attention with tensio-active agent and microbe oil production, surfactivity is driven and is demonstrated obvious superiority, wherein the main additive of oil driving liquid used is tensio-active agent, generally in using tensio-active agent, a certain amount of alkali or polymkeric substance are added therein, adding of alkali or polymkeric substance can make oil water interfacial tension lower, but, because alkali or polymkeric substance are adsorbed in a large number in stratum, stop up duct, stratum, destroyed stratal configuration, further exploitation has been brought to great difficulty.
Summary of the invention
The object of this invention is to provide a kind of oil-displacing agent that overcomes prior art problem.
Technical scheme of the present invention is: a kind of oil-displacing agent, is composited by following component:
A) sulfonated petro-leum, accounts for the 30%-70% of total mass;
B) surfactant adjuvant, accounts for the 20%-30% of total mass;
C) tensio-active agent synergistic agent 5%-15%;
D) surface active agent solubilization agent 3%-10%.
Further, described surfactant adjuvant is fatty alcohol-polyoxyethylene ether.
Further, described tensio-active agent synergistic agent is polyacrylamide.
Further, described surface active agent solubilization agent is ethanol.
Advantage and positively effect that the present invention has are: oil-displacing agent of the present invention does not need to add bases, environmentally safe in production process, and its consumption is 0.4%-0.6%, and usage quantity is little, and cost is low.
