More Information
Summary:The invention relates to a fracturing temporary plugging pitching process method based on perforation hole abrasion calculation, which comprises the following steps: S1, calculating the hole inlet abrasion amount of a perforation cluster under the erosion of fracturing prepad fluid and sand-containing fracturing fluid through a fluid-solid coupling numerical method, and updating the inlet diameter after hole abrasion; s2, according to the perforation cluster hole updating diameter, the temporary plugging ball diameter range and the temporary plugging ball number needed by temporary plugging are calculated; s3, adopting a fluid-solid coupling algorithm to analyze whether the pitching diameter and quantity design are appropriate or not, and if not, returning to B to adjust the design; s4, throwing the temporary plugging balls with different diameters into a shaft in batches through a ball throwing device; and S5, the temporary plugging ball is pumped to the target horizon perforation cluster.
