Torque impact generator



Product Description:LHE7701/LHE7702/LHE7703  Impact torque generator to be in the process of drilling with PDC bit are used together, the torque surge generato


Product Introduction


Product Description:LHE7701/LHE7702/LHE7703


  Impact torque generator to be in the process of drilling with PDC bit are used together, the torque surge generator connected to the PDC drill bit, drilling fluid kinetic energy can be transformed to the stability, uniform low-rising, high-frequency pulse torque impact, the impact and drill rotating system to produce torque is passed to the bit at the same time, a combination that can improve drilling speed, reduce slippage, sticking phenomenon, at the same time to reduce or eliminate the harmful vibration of the bit hard formation drilling process, protect the drill bit, at the same time of improving ROP (rate of penetration), prolong the service life of drill bit.

 

Speciality


◆ The mud kinetic energy is converted into torsional high frequency impact energy and transferred to PDC bit to improve the drillability of hard formation

◆ Increase the stability of PDC bit and eliminate errors and faults in directional well operation
 
◆ Increase the rate of mechanical penetration in harder rock formations

◆ Reduced trip times, cost savings and drilling time

◆ Increases bit life
 

 

Application


◆ This product is suitable for the down-set key type mud pulse generator, used for downhole drilling while surveying, producing mud pulse signal, and can be used for oil well deviation measurement, coal exploration, geological exploration and other fields
