Abstract
A cross-scale wide-spectrum particle size plugging formula granularity analysis method includes: performing a size classification on a plugging material of a plugging formula; obtaining a particle size distribution of the plugging material by performing procession on each particle plugging material via a laser granularity analysis method and an imaging granularity analysis method, according to difference sizes thereof; obtaining the particle size distribution of the plugging formula by a weighted summation way, according to a granularity interval and an addition of each particle plugging material. The present disclosure can solve a problem that the particle size distribution of the plugging formula across multiple-scale ranges can't be effectively obtained, and perform granularity analysis on wide-spectrum particle size plugging formula spanning a micron-grade size, a millimeter-grade size, a centimeter-grade size and above, so as to effectively evaluate sealing ability of the plugging formula and provide reference for researchers to optimize the plugging formula.
