Abstract:

In traditional acid concentration models, acid flow in the fracture is assumed to be one-dimensional flow and piston-like displacement without considering the acid flow across the fracture height and the vertical variation of reaction rate due to formation heterogeneity. In reality, vertical acid flow must exist during fracture height expending. In this work a 3D numerical model of acid transport and reaction is derived with consideration of acid flow across the fracture height. With this model, acid concentration distribution along the fracture length, fracture width and fracture height can be simulated.

Key words: acid fracturing, 3D model, acid corrosion distance, simulation
