High-Performance 3 3/4 Inch Oil-Resistant PDM Drilling Mud Motor(Model :9LZ95x7.0)

Product Introduction

Engineered specifically for demanding oil-based mud environments, the 3 3/4 Inch Oil-Resistant PDM Drilling Mud Motor (Model: 9LZ95x7.0) delivers exceptional downhole stability and precise trajectory control. At the core of this positive displacement motor lies a highly accurate multi-axis CNC-milled rotor, featuring a highly durable wear-resistant and anti-corrosive surface coating. This metallic rotor works in perfect interference fit with our proprietary anti-swelling rubber stator, custom-injected to withstand the chemical degradation typically caused by oil-based drilling fluids. You can physically feel the precise engineering in the smooth rotation and tight tolerances that prevent fluid bypass. Equipped with a standard 1.5° fixed bend angle and a 110mm stabilizer, it ensures reliable directional steering. The tool incorporates industry-standard NC31 threading at the drill pipe end and a 2 7/8 REG connection at the bit end, ensuring secure and immediate integration into your existing drill string. By maintaining consistent torque output under severe pressure drops, this mud motor dramatically extends operational periods before maintenance is required, making it an indispensable asset for complex directional and horizontal well construction.

Technical Parameters

The following technical parameters detail the precise operational capabilities of the 9LZ95x7.0 model. Engineered for metric and British system compatibility, this motor maintains a maximum power output of 81KW (108hp) and a maximum torque of 3209 N.m. The 9:10 lobe configuration and 4-stage design ensure optimal fluid displacement and rotational stability under a working pressure drop of 4.0 Mpa. Operators must adhere to these specifications, including the recommended flow rate of 450-900 LPM and a maximum weight on bit (WOB) of 55 KN, to maximize penetration rates and protect the elastomeric stator components from premature wear.

Product Uses

1. Conventional vertical oil & gas well drilling

This straight PDM mud motor provides steady, uninterrupted torque for the vertical borehole drilling of onshore oil and gas wells. By matching perfectly with regular PDC or tricone drill bits, it significantly improves drilling efficiency and rate of penetration in stable, conventional formations.

2. Oil well workover & casing remediation

Highly effective for routine downhole maintenance tasks, this tool excels in sand washing, wax clearing, and bridge plug milling operations. The streamlined straight body design allows it to pass smoothly through existing well casings, facilitating efficient wellbore restoration without damaging the internal metallic surfaces.

3. Shallow natural gas directional construction

The precision-engineered screw drilling tool supports slight deviation adjustments crucial for shallow gas exploitation. Its responsive steering capabilities adapt perfectly to soft and medium-hard formations, ensuring accurate trajectory placement for surface gas field development projects.

4. Geothermal well exploration drilling

Perfectly suited for shallow geothermal resource drilling, this durable downhole motor easily copes with the elevated formation temperatures and highly abrasive cuttings typical of geothermal boreholes. The heat-resistant stator formulation ensures continuous operation, reducing trip times and overall project costs.

Product Operate Guide

To ensure you maximize the operational value of your drilling equipment, we provide comprehensive maintenance and operational guidance. Proper management of drilling parameters—such as maintaining optimal weight on bit (WOB) and controlling fluid flow rates—is critical for extending the life of the anti-swelling stator in oil-based mud systems. Our detailed manual offers step-by-step instructions on pre-deployment checks, optimal fluid dynamics, and standardized operating procedures. By following these engineered guidelines, operators can fully leverage the 800-hour spare parts servicing kit, significantly reducing unexpected downtime and maximizing the return on your equipment investment.
