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
