RHEOLOGY CONTROLLED HETEROGENEOUS PARTICLE PLACEMENT IN HYDRAULIC FRACTURING |
| 摘要 |
A method of treating a subterranean formation penetrated by a wellbore includes preparing a treatment fluid with shear thinning, non-monotonic rheological properties, injecting the treatment fluid into the subterranean formation, and inducing shear rate softening phase transition in the treatment fluid. The non-monotonic rheology properties can be such that in the relationship between shear stress (s ) versus strain rate ( / ), where fx < j2 < /3 < /4, the shear stress values are s? < s2, (T3 < <T4, and <T3 < <T2. The method can heterogeneous Iy deposit proppant or solid acid in a fracture. A system to fracture a subterranean formation includes the fracturing fluid, a wellbore to inject the fracturing fluid to propagate a fracture in the formation, and a rate controller to inject the fracturing fluid into the subterranean formation at a minimum volumetric rate to provide a shear stress at an inlet to the fracture that exceeds CT2 - The method and system can achieve heterogeneous particle placement with either proppant or solid acid. |
