CORTECH® CMD100 Multi-Functional Large Diameter Deep Well Drilling Rig
Manufactured by Jinneng Holding Equipment Manufacturing Group | A Member of Jinneng Holding Group (Fortune Global 500 Enterprise)
Product Overview
The CORTECH® CMD100 is an ultra-heavy-duty, multi-functional full hydraulic top-drive drilling platform, masterfully engineered for high-consequence, large-diameter operations. Purpose-built to excel in deep crustal geology, this 55-ton industrial asset is the premier global choice for Coalbed Methane (CBM) extraction (including straight, directional, and horizontal multilateral branching wells), rapid strategic mine rescue operations, deep geothermal energy tapping, and large-diameter industrial water well construction.Featuring a colossal hoisting pullback capacity of 100 Metric Tons, the CMD100 is engineered to adapt flawlessly to complex downhole conditions through its absolute compatibility with Air Drilling, Mud Circulation Drilling, and Foam Fluid Drilling methodologies. Driven by a monumental 559 kW Cummins engine and engineered with an elevated 2.08-meter BOP-ready substructure, this heavyweight rig delivers unprecedented operational torque, site safety compliance, and robust reliability for global energy conglomerates and national disaster response frameworks.
Core Engineering Highlights & Commercial ROI
- Authoritative 100-Ton Pullback & Deep-Well Dynamics: Outfitted with a premium multi-circuit full hydraulic loop offering a 100T hoisting capacity and 20T pulldown force. This structural muscle allows safe handling of ultra-heavy, large-diameter extended casing strings and thick-walled drill pipes across immense vertical depths.
- Dual-Torque High-Speed Top Drive: The specialized 105 mm thru-hole spindle top drive delivers an enormous 27,500 N·m of continuous breakdown torque at low speeds (0-100 rpm) for aggressive formations, or transitions up to 300 rpm (9,700 N·m) for optimized crystalline rock shearing during large-diameter boring.
- BOP-Ready Elevated Work Substructure: Built with a specialized 2.08-meter high operating table and an expansive 810 mm centralizer opening. This safety-first geometry allows drilling engineers to rapidly mount standard pressure-rated Blowout Preventers (BOP), dust suppression arrays, and high-volume fluid diverters to enforce strict oilfield gas-kick compliance.
- Versatile Multi-Method Fluid Piping Architecture: Features heavy-duty, integrated onboard air/mud manifolds rated for 20.6 MPa continuous pressure resistance. Outfitted with auxiliary quick-connect ports, it allows rapid, independent coupling of external high-pressure air compressors, mud pumps, or foam injection arrays.
- Ferocious 559 kW Cummins Power Matrix: Powered by an immense 19L displacement Chongqing Cummins KTA19-P750 engine. Coupled with a 6-point independent heavy hydraulic outrigger stabilizer layout, it completely absorbs severe physical harmonics generated during heavy top-drive hammer drill runs on unpaved soils.
- Certified API Spec 4F Oilfield Compliance: The heavy-duty drilling masts (MASK & PSL 1) equipped on the CORTECH® CMD100 are fully backed by an official American Petroleum Institute (API) Monogram License (Certificate No. 4F-0504, Valid until August 9, 2027). This international gold-standard accreditation verifies that our structural steel fabrications strictly adhere to API Spec 4F engineering regulations.
- World-Class HSE & Standardized Manufacturing Compliance: The production infrastructure holding the CORTECH® series operates under an internationally audited, integrated management framework. The manufacturing floor is officially certified under ISO 9001:2015 (Quality Management System), ISO 14001:2015 (Environmental Management System), and ISO 45001:2018 (Occupational Health and Safety Management System), ensuring ultimate downhole safety and liability alignment for corporate energy programs.
