Note 2: Stabilizer’s OD, shape and length can be made as per customer’s request.

Note 3: The data listed above is general, which shall be finalized by customer based on drilling condition

and requirement.

2.2 Negative Pressure Pulse Tool (NPP)

NPP is designed on the basis of the principle that turbine stator and rotor is taken as the

power source to drive a planar valve, which can instantly interrupt or connect high-speed

fluids, then a negative pressure pulse is subsequently generated under the valve, and the

negative pressure pulse can be amplified and intensified by applying Helmholz resonator.

The tool integrates the advantages of rock breaking by hydraulic impact jetting and local

underbalanced rock breaking, which greatly enhances the drilling efficiency and the

migration effect of downhole cuttings. The average rate of penetration (ROP) is improved by

15-50% compared to that of normal pulse jet flow.

2.3 Oscillating Hammer

Oscillating hammer is characterized by its hydraulic incentive mechanical vibration

mechanism, which has circumferential vibration and axial vibration. Circumferential

vibration is stimulated by the impact force that is produced by the eccentric vortex of the

conjugating sealing process of the stator and the rotor, axial vibration is induced by the

hydraulic harmonic wave.

Features:



1) Reducing the drill string friction.

2) Improving the Tool Face control and ROP by cooperating with steering motor

system.

3) Reducing the stick-slip, improving the lifetime of bit and the departure of drill

string.

4) No negative influence on MWD systems.

Oscillating Hammer Performance Parameter

2.4 Motor Impactor

Motor impactor is powered by mud motor, which can create and transmit high frequent

impact force. Motor impactor can induce the BHA to make benign vibration, overcome drag

and friction, rotate and break the rock through impact force, thereof improve ROP.

Features:

1) No negative influence on the MWD systems.

2) Applicable for all kinds of drilling fluid, including air and Nitrogen system

(Multiphase flow system)

3) No limitation to the pump rate.

Motor Impactor Performance Parameter

2.5 Shock Antifriction Generator

When cooperated with Oscillating hammer, it can produce 3D vibration movement. When

Oscillating hammer’s pressure pulse work on the pressure-bearing surface of Shock

Antifriction Generator, the mandrel of Shock Antifriction Generator transmits the pressure

pulse into mechanical motion, thus complete the vibration. Shock Antifriction Generator can

effectively reduce the friction of the BHA with steering motor, improve the WOB

transmission, thus improve the max drilling depth and Tool Face controllability, reduce

downhole vibration, and improve ROP.

Features:

1) Improving ROP

2) Reducing the risk of stuck pipe and stick-slip.

3) Controlling torque vibration, prolonging lifetime of drill string.

4) Reducing motor braking, prolonging lifetime of motor.

5) Reducing Tool Face orienting time.

6) Reducing drill pipe buckling.

7) Reducing WOB required on the surface.
