Abstract:

Perforation is important to fracture initiation and propagation in horizontal wells.This study puts forward an in-plane perforation methodology to decrease the breakdown pressure and improve the fracture-wellbore connection,and large-scale polyaxial tests are deployed to confirm the idea.The breakdown pressure of the tests is compared to those of four models,and also the fracture geometry is observed and analysed.The tests show that the in-plane perforation which means perforation holes and tunnels in the same plane and perpendicular to the minimum horizontal stress reduces the breakdown pressure effectively,and also reduces the near wellbore tortuosity and improves the fracture-wellbore connection.These observation and findings could be used to optimize the perforation and fracturing jobs on site.

Key words: Breakdown pressure, Fracture geometry, Horizontal well, Large-scale polyaxial test, In-plane perforation, Perforation penetration depth
