✦ Synopsis

Horizontal well hydraulic fracturing is a complex technology and there is no clear understanding about the mechanics of hydraulic fracturing. The Fluid-solid coupling elements were used to describe the behavior of rock, and the pore pressure cohesive elements were employed to simulate the process of fracture initiation and propagation. The fluid flow in the fractures and fracturing fluid leakoff effects were also taken into account. By adopting field data, the staged fracturing process of a horizontal well in Daqing Oilfield, China was simulated. The simulated results are fit well with the field treatment data.
