Downhole Shaft Type Positive Displacement Mud Motor
7 5/8" Drilling Tool Downhole Shaft Type Mud Motor
Product Overview
Downhole drilling motor is a powerful and reliable positive displacement motor. The motor generates an optimum balance of rotational speed and high torque to drive a variety of drill bits at speeds that maximize tool life and performance.We offers a choice of flow rates, speeds, and torques to match a wide range of operational parameters. we are used in applications such as straight hole drilling, directional (steerable) drilling, horizontal drilling, hole opening, and re-entry(work over).
We can produce series of downhole motors in different sizes, as Φ57(21/4"),Φ73(23/4"),Φ89(31/2"),Φ95(33/4"),Φ120(43/4"),Φ127(5"),Φ165(61/2"),Φ172(63/4"),Φ178(7"),Φ185(71/4"),Φ197(73/4"),Φ203(8"),Φ216(81/2"),Φ244(95/8"), etc.
Types & Capabilities
In accordance with the actual drilling needs, we push out high, midiem and low speed downhole motors, of a variety of types with different functional configuration and application for all working conditions.
- Oil-stransmission shaft type ealed It improves the working condition of thrust bearing and radial bearing, and increases the life span of each single trip.
- Bend angle adjustable type We equip the motors with adjustable bend housing in different types and sizes, and through which before dropping we can adjust the bend angle.
- Saturated saltwater mud resistance type The special coating on the rotor with strong ability of anti-corrosion and wear-resistance enables the motor to work stably for a long time in the condition of saturated saltwater mud.
- Impact Resistance Type We adopt a series of shock absorbers to lighten or eliminate bit jumping and impact shock occurring in drilling, protect the drilling tools avoiding damage, increase service life and ensure the drilling safe and efficient. ( style impact resistance downhole motor is our new technology patent products. Patent No ZL2011 2 0000193.2)
