Viscous torques characteristics in a self-rotating jet bit with silicone oil-controlled rotational speeds
Rock-breaking drilling using a self-rotating jet bit with a controllable speed can improve the efficiency of coalbed methane development using the water jet tree-type borehole technology. The viscous torque generated by filling silicone oil inside the bounded annular column of the bit can control th...
