Hydraulic jet fracturing string introduction
 
Though hydraulic abrasive perforating after forming channels in the

reservoir then continue jetting， under the action of high pressure water

jet the pore formed and pressurized while enhancing annulus pressure,

when the bore pressure exceed formation breakdown pressure the layer

breakdown immediately, then realize hydraulic jet fracturing.

The concept of hydraulic jet fracturing：
