HYDRAULIC THRUSTER

Features:

• The thruster work by using drilling fluid hydraulics without consuming hydraulic power.
• The thruster is made up of one or more cylinders and can be used with down hole motor, which is applicable to any wells.
• With the long stroke length and the liquid elasticity absorption, the thruster can damp axial vibration effectively, and compensate slide drilling that is out of control.
• The design of choke spear enlarges the range of WOB and allows easy adjustment.
• Application of the thurster can bring better drillstring dynamics, resulting in increase of down hole motor life time, better direction behaviour and increase of penetration rate.
