Non-Magnetic Drilling Components for Directional Drilling

Engineered by Shanxi Jinneng Holding Equipment Manufacturing Group—a core subsidiary of Jinneng Holding Group, a Fortune Global 500 enterprise—we deliver high-precision non-magnetic drilling components that ensure zero magnetic interference in the most demanding directional drilling operations. Our products are field-proven in over 500 coalbed methane (CBM) drainage projects across China, as well as in deep oil and gas wells in complex geological formations.

Engineered for Zero Magnetic Interference

Every component is manufactured from high-purity austenitic non-magnetic steel, rigorously tested to achieve relative permeability μr ≤ 1.005, and built with anti-galling cold-rolled threads and pressure-sealed cable pass-through systems validated under 20MPa. This ensures reliable MWD/LWD signal transmission even in long-reach, high-torque boreholes.

Our core product range includes:

Non-Magnetic Drill Pipes

Designed for both mining and oilfield directional drilling, capable of depths exceeding 1,500 meters while eliminating magnetic distortion. Ideal for in-seam gas drainage in gassy coal seams.

l Non-Magnetic Measurement Sub Housings

Precision outer casings for MWD/LWD probe assemblies, engineered for uniform magnetic response and minimal signal noise.

l Non-Magnetic Cable-Pass-Through Check Valves

Hydraulic safety valves with sealed central channels for real-time telemetry cables—critical for continuous data flow during drilling.

l Full Non-Magnetic Screw Motors (Mud Motors)

Entire motor assembly constructed from non-magnetic material to prevent localized anomalies that compromise steering accuracy.

l Non-Magnetic Drill Collars

Heavy-weight collars for bottom hole assemblies (BHA), providing consistent weight-on-bit without interfering with magnetic survey tools.

Certified for Dual Environments

Mining applications: All components carry the mandatory China Coal Mine Safety Mark (MA).

Oilfield applications: Fully compliant with API 7-1 dimensional and performance standards.

Full Technical Documentation & Traceability

As an OEM for national mine safety and energy governance programs, we provide complete material traceability, third-party test reports (SGS/BV), and detailed technical manuals—ensuring compliance, reliability, and seamless integration into critical drilling operations.

Backed by the scale and manufacturing excellence of Jinneng Holding Group (Fortune Global 500), we maintain rigorous quality control from raw material to finished product, delivering consistent performance for the most challenging directional drilling tasks.
