  • Method for optimizing perforation parameters to maintain uniform fracture growth in multi-stage hydraulic fracturing of horizontal well
    Patent number: 10677961
    Abstract: A method for optimizing perforation parameters to maintain uniform fracture growth in multi-stage hydraulic fracturing of horizontal well and device therefor are provided. The method includes steps of: S1: collecting the geological and engineering parameters of the targeted pay zone, and estimating the net inlet pressure of fractures within the targeted fracturing stage of horizontal well; S2: calculating the perforation friction coefficient required for maintaining the uniform fracture growth in multi-stage hydraulic fracturing of horizontal well; S3: calculating the perforation characteristic parameter; and S4: determining the optimized perforation parameters. The method considers the stress heterogeneity, the stress shadowing and the perforation erosion in the process of dynamic hydraulic fracturing propagation, and also the influence of perforation erosion.
