摘要
Film coated particles for oil exploitation, fracturing proppants comprising the film coated particles and oil exploitation method using the fracturing proppants are disclosed. The film coated particles comprise skeleton aggregates and film which is oil-permeable and water-blocking covering the surface of the skeleton aggregates. The film coated quartz sand and the fracturing proppants are oil-permeable and water-blocking in conventional atmospheric pressure condition, and the resistance to oil permeation is remarkably lower than the resistance to water permeation in pressurized conditions. Thereby in oil exploitation industry, water output is reduced effectively and oil yield is increased.
