•It is used for staged fracturing in the string and staged fracturing in cementing, and the number of fractured layers is not limited. •The ID of all sliding sleeves is the same, and there is no...

•It is used for bridge plug perforation and block segmented fracturing, and the number of fracturing layers is not limited. •Automatic dissolution and pressurization without wellbore intervention.

•Using hydraulic drive cutting blade outer tensioning,rotary cutting string.

•Use the pressure differential generated by the piston nozzle to extrapolate the reaming blade to achieve the purpose of reaming.

•The tool can automatically adjust the drilling pressure according to the torque of the drill bit to ensure that the drill bit rotates at a nearly uniform speed. •The tool can prevent downhole...

•The tool is powered by drilling fluid, which causes the drill string to produce high-frequency axial vibration, thereby changing the static friction of the sliding drilling tool into dynamic...

In conjunction with the whipstock to mill out a window on the casing wall along the bevel of the whipstock.

The use of hydraulic pressure to set,and then the window milling cone is used,to mill out a window on the casing wall along the bevel of the whipstock.
