Manufactured by Jinneng Holding Equipment Manufacturing Group | A Member of Jinneng Holding Group (Fortune Global 500 Enterprise)

Product Overview

The CORTECH® CMD Series represents a world-class portfolio of ultra-heavy-duty multi-functional full hydraulic top-drive large diameter drilling rigs, masterfully engineered for high-consequence energy, geothermal, and industrial deep-well operations. Purpose-built to conquer heavy casing strings and complex crustal formations globally, this high-tier heavy land rig lineup is fully optimized for advanced multi-fluid drilling methodologies, including Air DTH Hammer Drilling, Mud Circulation Drilling, and Air-Lift Reverse Circulation (ALRC).

Spanning an authoritative hoisting pullback capacity from 100 Metric Tons to an immense 180 Metric Tons, the CMD Series completely redefines large-bore deep drilling metrics. Universally adapted for straight, directional, and horizontal multilateral branching wells, our rigs integrate elite industrial assets like API 4F certified drilling masts, BOP-ready elevated substructures, wireless remote walking systems, and automated iron roughnecks. The CMD series delivers the ultimate combination of precision weight-on-bit (WOB) balancing control, continuous structural torque delivery, and unmatched engineering safety guidelines for global energy conglomerates and national disaster response programs.

Core Advantages & Engineering Highlights

· API Spec 4F Certified Engineering Integrity: The heavy-duty structural steel masts, telescoping frames, and lifting structures across the full CMD lineup hold an official American Petroleum Institute (API) Monogram License (Certificate No. 4F-0504). Fully audited to comply with API Spec 4F and API Spec Q1 quality management frameworks, this ensures total legal and operational compliance on high-risk oil and gas sites worldwide.

· Massive Pullback & Dual-Torque Spindle Controls: Outfitted with multi-circuit high-pressure hydraulic loops providing continuous pullback forces from 100T up to 180T. Backed by top-drive heads generating up to 41,000 N·m of continuous breakdown torque, our rigs seamlessly run heavy large-diameter casings and thick-walled drill pipes at immense vertical horizons.

· BOP-Ready Elevated Substructure Design: Built with specialized operating floors and substructures establishing clear workspace heights from 2.08m up to a staggering 5.5m (including advanced Slingshot Hydraulic Lifting Frameworks). This safety-first geometry grants drilling engineers ample clearance to rapidly mount standard pressure-rated Blowout Preventers (BOP), heavy fluid diverters, and oilfield well control manifolds to mitigate gas-kick hazards.

· Heavy-Duty High-Pressure Fluid Manifolds: Features integrated onboard air/mud piping networks rated for 20.6 MPa to 35 MPa maximum continuous pressure resistance with nominal inner diameters up to 100 mm. Quick-coupling auxiliary ports permit instant, seamless attachment to external high-capacity air compressor banks, foam injection systems, or massive oilfield mud pumps.

· World-Class HSE & Standardized Manufacturing Compliance: Every single rig is fabricated within our state-of-the-art heavy industrial manufacturing base, operating under internationally audited system standards officially certified under ISO 9001:2015 (Quality), ISO 14001:2015 (Environmental), and ISO 45001:2018 (Occupational Health & Safety).

Strategic Industry Applications

· Unconventional Oil & Gas & CBM: Optimized for high-accuracy directional reaming and extended horizontal runs in low-pressure, fragile Coalbed Methane (CBM) gas field matrices.

· Deep Geothermal & Mega Water Wells: Purpose-built for boring large-bore holes up to 820 mm to tap deep industrial water matrices and sustainable geothermal hot-dry-rock energy reservoirs.

· Mine Ventilation & Rapid Crisis Rescue: Trusted globally for drilling high-diameter ventilation shafts and boring rapid, large-scale emergency escape passages during underground mine collapse crises.

FAQ

Q1: What unique logistics and terrain benefits do the diverse chassis forms (Truck, Track, and Modular) provide in the CMD Series?

A1: To eliminate mobilization friction across vastly different international projects, the CMD Series offers three distinct mobility architectures. The Truck-Mounted CMD130 (10×8 chassis) optimizes transit down to a 54.5t legal weight, enabling independent highway driving between fields without lowboys. The Track-Mounted CMD130L/DL utilizes rugged steel crawlers with wireless remotes to independently climb 30° wilderness slopes. For inaccessible environments without roads, the Modular CMD150/180 allows the entire 60-ton framework to split into individual pin-connected skids for standard overland trucking or helicopter hoisting.

Q2: How do the BOP-ready elevated substructures and slingshot mechanisms ensure gas field compliance?

A2: Deep water well, geothermal, and CBM gas-field operations carry persistent risks of gas kicks and geological pressure surges. CMD rigs feature elevated operating tables from 2.08m up to a monumental 5.5m paired with wide centralizer openings. In our flagship CMD180, a specialized Slingshot Substructure allows the entire drilling floor and top drive to be rigged up safely at near-ground level, before being raised smoothly into position via heavy hydraulic cylinders. This provides full overhead space to rapidly fit high-pressure Blowout Preventers (BOP) and diverters to enforce strict oilfield well control compliance.

Q3: What operational benefits does the dual parallel engine setup provide on flagships like the CMD150 and CMD180?

A3: Reaching extended depths with immense reaming torques requires rigid, fail-safe power delivery. Our modular flagships integrate twin Cummins diesel engines (up to 1,520 hp combined) operating in a parallel network. This dual-engine setup provides built-in mechanical redundancy: if one engine requires emergency maintenance mid-operation, the secondary power source independently maintains vital hydraulic circulation pressures to prevent downhole tools from jamming or sticking, saving contractors from catastrophic string losses.
