Advanced Horizontal Directional Drilling Downhole Mud Motor, 5-516

Product Introduction

Advanced Horizontal Directional Drilling Downhole Mud Motor, 5-5/16"

The Model 7LZ135-5-1 represents a highly dependable mud motor engineered specifically for the rigorous demands of complex directional drilling. When field engineers handle this equipment, the dense, solid weight of the heavy-duty alloy steel rotor immediately communicates its structural integrity. Paired with a specialized high-temperature-resistant stator rubber formulation, this motor is built to withstand extreme downhole environments, resisting chemical degradation and preventing premature wear even when pumping highly abrasive drilling fluids.

Equipped with a fixed bend angle of 1.25° and a robust 165 stabilizer, this downhole tool provides operators with precise trajectory control, effectively dampening destructive downhole vibrations that can damage sensitive measurement equipment. The exterior undergoes precision CNC machining and receives a specialized anti-corrosion, wear-resistant coating, leaving a smooth, friction-reducing finish that significantly enhances structural strength and fatigue resistance during prolonged rotational cycles.

For secure integration into your drill string, it utilizes an NC38 thread at the drill pipe end and a 3 1/2 REG connection on the bit end, strictly complying with API standards for a safe, leak-free assembly. Perfectly suited for medium-radius horizontal wells, conventional oil and gas extraction, and highly abrasive rock formations, this positive displacement motor (PDM) delivers a steady hum of consistent torque output. It ensures stable running performance, accelerates drilling progress, and ultimately reduces operational downtime for drilling contractors.

Product Uses

Application Scenarios of Xinyongjia 7LZ135-5-1 Straight Downhole Mud Motor

1. Conventional vertical oil & gas well drilling

This straight PDM mud motor provides a steady, powerful torque stream specifically required for vertical borehole drilling of onshore oil and gas wells. By perfectly matching with standard roller cone or PDC drill bits, it improves mechanical penetration rates (ROP) and ensures a straight, clean wellbore path in stable conventional formations, reducing the time spent tripping pipe.

2. Oil well workover & casing remediation

Field crews heavily rely on this motor for routine downhole maintenance tasks, including heavy sand washing, stubborn wax clearing, and precision bridge plug milling. The straight body profile and smooth exterior coating allow it to pass smoothly through existing production casings without hanging up, facilitating rapid oilfield wellbore restoration and bringing wells back online faster.

3. Shallow natural gas directional construction

When dealing with shallow gas exploitation, the straight screw drilling tool supports the slight deviation adjustments necessary to hit specific reservoir targets. It adapts exceptionally well to soft and medium-hard formations encountered during surface gas field development, providing the exact rotational speed needed to prevent washouts in softer rock layers.

4. Geothermal well exploration drilling

Engineered for extreme conditions, this motor is highly suitable for shallow geothermal resource drilling projects where High-Temperature, High-Pressure (HTHP) environments are common. The durable downhole motor, featuring its specialized stator rubber, easily copes with elevated formation temperatures and extreme abrasion, ensuring continuous operation during demanding geothermal borehole construction.
