Durable 6-3/4" PDM Mud Motor for Efficient Drilling Operation(Model 7LZ172x7.0)

Product Introduction

The Model 7LZ172x7.0 Positive Displacement Motor (PDM) is a meticulously engineered downhole mud motor measuring 8.4 meters in overall length. Upon physical inspection, operators will immediately notice the heavy-duty, abrasion-resistant metallic finish—cool to the touch and carrying the faint, distinct scent of industrial protective fluids. The precisely machined 4 1/2 IF thread at the drill pipe end pairs perfectly with a 4 1/2 REG connection at the bit end. These API-standard connections ensure a secure, vibration-dampening assembly for stable torque transfer deep underground. The internal architecture features an optimized stator and rotor configuration crafted from highly wear-resistant elastomer, designed specifically to handle extreme pressure differentials. This core power section translates fluid hydraulic energy into continuous, high-torque mechanical power. Complementing this is a heavy-duty bearing and transmission system equipped with a high-strength universal shaft, guaranteeing smooth power delivery and exceptional impact resistance even when encountering sudden lithology changes. By effectively boosting penetration rates and resisting wear in harsh subterranean environments, this mud motor serves as an indispensable tool for complex oil and gas well construction.

Technical Parameters

Product Uses

1. Conventional vertical oil & gas well drilling

This straight PDM mud motor provides steady, unyielding torque for vertical borehole drilling of onshore oil and gas wells. By matching regular drill bits, it drastically improves drilling efficiency and stabilizes penetration in conventional formations. The optimized power section ensures consistent RPMs, helping crews reach target depths faster without premature wear on the elastomer components.

2. Oil well workover & casing remediation

It applies perfectly to routine downhole maintenance tasks including sand washing, wax clearing, and bridge plug milling. The straight body smoothly passes through narrow casings, restoring wellbore integrity. The heavy-duty bearing system absorbs the intense radial shocks generated during milling operations, preventing secondary damage to the existing infrastructure.

3. Shallow natural gas directional construction

Featuring a 0-3° adjustable bent housing mechanism with precise scale markings and an anti-drop gear design, this tool supports the slight deviation adjustments essential for shallow gas exploitation. It adapts seamlessly to soft and medium-hard formations, optimizing surface gas field development while allowing operators to securely and rapidly adjust the wellbore trajectory angle on-site.

4. Geothermal well exploration drilling

Highly suitable for shallow geothermal resource drilling projects. The durable downhole motor copes effortlessly with common formation temperatures and intense abrasion. The wear-resistant rubber stator maintains its structural integrity against the abrasive cuttings typical of geothermal exploration, ensuring continuous progress for borehole construction in challenging rock layers.
