| titleOfInvention | Intelligent oil displacement agent capable of automatically finding oil and preparation method thereof |
| abstract | The invention relates to an intelligent oil displacement agent capable of automatically finding oil and a preparation method thereof. The method comprises the following steps: mixing and stirring the sulfonate surfactant and the sulfate surfactant uniformly in a reaction kettle; adding a higher alcohol to the mixture; adding an oil-water recognition enhancer into the system; adding thiosulfate with the total mass of 2-5% into the system; and adding chloride into the system, and uniformly stirring to obtain the intelligent oil displacement agent. The oil displacement agent glue solution has the oil-water identification more than 100 times. |
