Types | Sand carrying ability | Fracture making ability | Damaging | Cost | Confection |
Reactive water fracturing fluid | Weak low viscosity, transport propping agent relay on the displacement, usually short transport distance | Weak low viscosity, limited transformation scale; the vertical extension of fissures are difficult to control | Low | Low | East to confect and not limited by temperature |
Gelled fracturing fluid | Strong transport propping agent relaying on viscosity and displacement, long transport distance | Strong high viscosity, the displacement, transformation scale and vertical extension of fissures are easy to control | High | High | Complex and high quality requirements |
Clean fracturing fluid | Strong transport propping agent relaying on the viscosity and displacement, long transport distance | Strong high viscosity, the displacement, transformation scale and vertical extension of fissures are easy to control | Medium | High | High quality requirements and limited by temperature |
Foam fracturing fluid | Strong transport propping agent relaying on the viscosity and displacement, long transport distance | Strong high viscosity, the displacement, transformation scale and vertical extension of fissures are easy to control | Low | High | Easy to confect, complicated construction procedure |
