  • Publication number: 20120088699
    Abstract: The present invention discloses coated particles for oil recovery, a fracturing propping agent that comprises the coated particles, and an oil recovery method that utilizes the fracturing propping agent. The coated particles comprise particles of aggregates and an oil-permeable and water-proof film coated on the particles of aggregates. The coated quartz sand and fracturing propping agent are oil-permeable and water-proof under normal atmospheric pressure, and have oil permeation resistance much lower than water permeation resistance in pressurized state. Therefore, when the coated quartz sand and fracturing propping agent are applied in the oil recovery industry, they can effectively reduce the volume of produced water and increase the oil yield.
