Durable 4 3/4" Downhole Mud Motor for Efficient Drilling Operations(Model 7LZ120x7.0)

Product Introduction

Engineered for demanding directional and horizontal drilling operations, the 7LZ120x7.0 (4 3/4") positive displacement mud motor delivers exceptional well trajectory control and reliable build rates. At the core of this power section is a stator formulated from specialized high-temperature resistant HNBR (Hydrogenated Nitrile Butadiene Rubber), paired with a rotor featuring an advanced HVOF (High-Velocity Oxygen Fuel) tungsten carbide coating. This meticulous surface treatment ensures an ultra-hard, wear-resistant interface that dramatically extends operational lifespan even in highly abrasive environments. Built to endure extreme downhole conditions, the motor maintains structural integrity and consistent torque output at elevated temperatures ranging from 150°C to 180°C. Furthermore, the specialized elastomers and sealed bearing assemblies offer superior resistance to corrosive oil-based muds (OBM) and high-salinity drilling fluids, providing operators with unwavering confidence when navigating complex geological formations. With a standard 1.5° fixed bend angle, 311 connection at the drill pipe end, and a 330 thread at the bit end, it guarantees stable mechanical coupling and optimal energy transfer, effectively minimizing non-productive downtime across demanding onshore oil and gas projects.

Technical Parameters

To maximize the rate of penetration (ROP) across varying stratigraphies, understanding the hydraulic and mechanical capabilities of your bottom hole assembly (BHA) is crucial. The 7LZ120x7.0 model features a 7:8 lobe configuration and a 4-stage power section, producing an optimal balance of torque and rotational speed. This specific lobe ratio makes it exceptionally compatible with modern PDC bits for medium-to-hard rock drilling, as well as tricone bits for specialized applications, ensuring efficient weight-on-bit (WOB) transfer and superior hydraulic horsepower utilization.

Product Uses

1. Conventional vertical oil & gas well drilling

This straight PDM mud motor provides steady, continuous torque for vertical borehole construction in onshore oil and gas fields. When paired with standard drill bits, it optimizes cutting efficiency in stable conventional formations. We also offer customization options, including 0° to 3° adjustable bent housings, to meet specific trajectory requirements.

2. Oil well workover & casing remediation

Highly effective for routine downhole maintenance tasks, including sand washing, wax clearing, and bridge plug milling. The precision-machined straight body passes smoothly through existing production casings, facilitating efficient wellbore restoration without damaging the internal tubular structures.

3. Shallow natural gas directional construction

This screw drilling tool supports precise deviation adjustments essential for shallow gas exploitation. It adapts readily to soft and medium-hard formations, while our OEM capabilities allow for tailored hydraulic parameter adjustments to suit unique surface gas field development projects.

4. Geothermal well exploration drilling

Perfectly suited for shallow to medium-depth geothermal resource extraction. The thermally stable elastomers and durable downhole motor components easily cope with the elevated formation temperatures and abrasive cuttings typically encountered during geothermal borehole construction.
