HYDRAULIC FRACTURING METHOD |
| 摘要 |
Methods relating to using fracturing fluids in fracturing process for fracturing of subterranean formations are provided. The methods comprise sequentially injecting into a wellbore, alternating stages of a low-viscosity fracturing fluid having a first viscosity and a high-viscosity fracturing fluid having a second viscosity, wherein there is a viscosity difference such that the first viscosity is lower than the second viscosity. |
