Durable 4 Inch Downhole Mud Motor with Fixed Bending Angle Technology(Model:5LZ101X7.0)

Product Introduction

Engineered specifically for demanding trenchless horizontal directional drilling and complex subterranean routing, the 5LZ101X7.0 mud motor provides exceptional trajectory control. The tool features a fixed bend angle of 1.75 degrees, allowing operators to navigate complex geological paths with absolute confidence. At its core, the motor utilizes a high-strength alloy steel rotor paired with a wear-resistant rubber stator. These critical components are crafted using advanced CNC precision milling, delivering a heavy, tactile solidity that withstands intense subterranean friction and abrasive forces. The drill pipe end is equipped with a 211 connection, while the bit end utilizes a 330 thread, fully complying with rigorous oilfield standards for secure fastening and steady mechanical torque transfer. To further enhance operational reliability, this model is outfitted with a highly engineered modular internal structure, including an optimized bypass valve, a durable flexible shaft or universal joint, and high-performance thrust bearings. It features an advanced anti-mud erosion sealing system—available in either oil-sealed or mud-lubricated configurations depending on your specific project needs. We also offer flexible configuration options, supporting high build rates and extended lengths to precisely match complex directional drilling requirements. Emitting a rhythmic, steady hum of power during operation, this positive displacement motor (PDM) effortlessly converts hydraulic fluid energy into mechanical rotation, minimizing project risks, extending the operational lifespan of a single run, and boosting overall drilling precision.

Technical Parameters

Product Uses

1. Conventional vertical oil & gas well drilling

This straight PDM mud motor provides steady, continuous torque for vertical borehole drilling across onshore oil and gas fields. By matching with standard drill bits, it optimizes penetration rates in stable conventional formations, turning heavy geological resistance into manageable progress. The reliable mechanical output ensures that drillers can maintain optimal weight on bit without stalling.

2. Oil well workover & casing remediation

Designed for routine downhole maintenance, this tool excels in challenging tasks such as sand washing, wax clearing, and bridge plug milling. The smooth metallic finish of the straight body allows it to pass safely through existing casings, facilitating efficient wellbore restoration without damaging the surrounding infrastructure. It operates with a quiet, powerful efficiency that operators can rely on during delicate remedial work.

3. Shallow natural gas directional construction

The straight screw drilling tool supports slight deviation adjustments crucial for shallow gas exploitation. It adapts readily to soft and medium-hard formations, providing the controlled directional force needed for surface gas field development and extraction. The fixed 1.75-degree bend angle provides the exact trajectory control required to navigate these specific geological layers safely and effectively.

4. Geothermal well exploration drilling

Highly suitable for shallow geothermal resource projects, this durable downhole motor handles the elevated temperatures and abrasive rock cuttings typical of geothermal boreholes. Featuring advanced heat-resistant configurations capable of withstanding up to 175°C, along with superior shock-absorbing capabilities, its resilient construction ensures continuous, stable torque output even when exposed to harsh thermal and friction-heavy hard rock environments.

Product Operate Guide

To maximize the lifecycle and efficiency of your 4-inch mud motor, strict adherence to proper field operation protocols is essential. Our comprehensive guidelines cover critical pre-deployment surface testing procedures to verify hydraulic integrity and mechanical responsiveness before the tool enters the wellbore. Operators will find detailed parameters for controlling drilling dynamics, including precise pump-stop mechanisms to prevent stalling under heavy loads. Furthermore, the guide outlines post-drilling maintenance, detailing the necessary flushing and cleaning routines to remove abrasive particulate matter from the stator and rotor interface. We also provide thorough troubleshooting procedures, clear anti-sticking operation standards, and precise wear measurement criteria for the power section. By following these structured maintenance steps and utilizing the designated spare parts, crews can significantly reduce human-induced malfunctions, extend the operational life of the equipment, and optimize overall project expenditures.
