HJC Constitutive Model
The Holmquist-Johnson-Cook (HJC) constitutive model is a critical component, effectively characterizing large deformation behavior of rock materials under dynamic impact processes. It consists of an equation of state, a strength model, and a damage model, involving 21 parameters for accurate simulation. This model is crucial for understanding rapid changes in high strain rates during deflagration fracturing.
Deflagration Fracturing Mechanism
Deflagration fracturing creates a high-pressure environment that induces rock fragmentation and fracture formation. The process involves rapid combustion of gunpowder generating high-temperature, high-pressure gas. This pulse loading method releases significant energy, forming a fragmented zone and an initial crack zone, which enhances reservoir transformation.
Evaluation of Fracturing Effectiveness
The effectiveness of deflagration fracturing is assessed by analyzing the propagation range of deflagration waves and the volume of reservoir reforming. Simulation results show a nonlinear relationship between drug volume and deflagration reach, with larger drug volumes leading to greater energy release, increased reforming volumes, and improved production capacity.
