Overview

Randomized trial examines the impact of perforation patterns on fracture initiation in tight sandstone, revealing optimization strategies.

Key Points

  • The study aims to optimize fracture propagation during perforation fracturing by analyzing engineering parameters and introducing dimensionless parameters.
  • Conducted sensitivity analysis using the discrete lattice method.
  • Established single-cluster models for different perforation patterns and validated them against near-wellbore simulations.
  • Developed a multi-cluster fracturing model to analyze competitive propagation and geometrical patterns.
  • Helical perforation produced the highest breakdown pressure and largest initiated crack volume.
  • Increasing helical perforation diameter and depth while reducing density improved stimulated reservoir volume (SRV) and reduced SRV standard deviation.
  • Cluster length and spacing had limited effects on breakdown pressure but increasing them reduced SRV standard deviation.
