FILM COATED PARTICLES FOR OIL EXPLOITATION AND OIL EXPLOITATION METHOD USING THE SAME

摘要

Film coated particles for oil exploitation, fracturing proppants comprisingthe film coatedparticles and oil exploitation method using the fracturing proppants aredisclosed. Thefilm coated particles comprise skeleton aggregates and film which is oil-permeable andwater-blocking covering the surface of the skeleton aggregates. The filmcoated quartzsand and the fracturing proppants are oil-permeable and water-blocking inconventionalatmospheric pressure conditions, and the resistance to oil permeation isremarkably lowerthan the resistance to water permeation in pressurized conditions. Thereby inthe oilexploitation industry, water output is reduced effectively and oil yield isincreased.
