Abstract
The disclosure belongs to the technical field of well completion engineering in oil and gas engineering, and particularly relates to a high-flow-conductivity proppant and its preparation method. The high-flow-conductivity proppant includes dumbbell-shaped framework granules and an oil-soluble film coating layer coated on the surfaces of the framework granules; the oil-soluble film coating layer melts when meeting oil at the temperature of 30-120° C. The high-flow-conductivity proppant prepared by the method has low bulk density, and the problems that the traditional proppant cannot be transported to the far end of a crack, has poor flow conductivity and the like can be effectively solved.
