Key Features & Technologies
API-Certified for Global Operations
SJ is authorized to use API monograms on products under API 4F (drilling and well servicing structures), 7K (drilling equipment), 8C (derricks and masts), 6A (wellhead equipment), and 16C (choke and kill equipment). Our manufacturing facilities also hold API Q1, ISO 9001, and HSE management system certifications.
These aren't decorative badges. Each API license subjects our facility to regular third-party audits covering design verification, material traceability, manufacturing processes, and quality control documentation. When your regulatory authority or insurance underwriter demands proof of compliance, SJ provides documentation that passes scrutiny.
Caterpillar + Allison Powertrain – Serviceable Anywhere
We don't use obscure, proprietary components that leave you stranded when something breaks. Our land drilling rigs are powered by Caterpillar diesel engines (C9 through C18 and larger) paired with Allison Oil Field Series transmissions.
The Allison hydraulic transmission gearbox driven by one or two Caterpillar diesel engines provides reliable transmission and has longer service life. This is the combination that operators around the world trust—because when your rig is two days from the nearest parts warehouse, you need to know that replacement components are available. With Caterpillar and Allison's global dealer networks, they are.
Hydraulic Mast Erection – No Crane Required
Our mast is a front-open, two-section type telescoping structure that can be erected or lowered and telescoped hydraulically, all without external crane assistance. The drill floor is a folded type or parallelogram structure, which is convenient to be lifted and carried. This eliminates crane rental costs, reduces on-site personnel exposure, and significantly cuts rig-up time.
Factory Pre-Wiring and Pre-Piping
Every electrical circuit, hydraulic line, and pneumatic connection is installed and tested at our 50,000-square-meter assembly yard in Jingzhou, not wired in the field by crews who may or may not be familiar with our rigs. When your land drilling rig arrives on site, you're hooking up a complete, factory-tested machine, not piecing together a puzzle.
Dual-Purpose Drilling & Workover Capability
Many of our land drilling rigs, particularly the ZJ series, are dual-purpose machines capable of both drilling new wells and performing heavy workover operations. ZJ40 can reach up to 4,000 m drilling depth and 10,000 m workover depth. This flexibility means one rig can serve two functions, reducing your capital and operating costs.
Extreme Climate Engineering
SJ has delivered land drilling rigs to some of the most challenging environments on earth:
-
Arctic/cold-weather rigs (low-temperature drilling rigs) operate normally from +45°C down to -45°C and can be stored down to -60°C, with cold-weather materials, heat preservation processes, low-temperature lubricants, and heated enclosures. Field-proven on ZJ40 rigs delivered to Orenburg, Russia.
-
Desert rigs (desert drilling rigs) feature enhanced cooling systems, high-efficiency sand and dust filtration, reinforced seals, and wide-track tire configurations for operation in +50°C ambient temperatures. Deployed successfully in Kuwait and across the Middle East.
Our land drilling rigs are also suitable for mountain, marsh, tidal flat, and high-altitude environments.
Applications
SJ land drilling rigs have been deployed across six continents for a wide range of operations.
Oil & Gas Exploration and Development
This is our core market. Our land drilling rigs are used for wildcat exploration wells, appraisal drilling, development programs in mature fields, infill drilling between producing zones, and deep-well exploration. SZJ series modular rigs can handle depths up to 9,000 m for ultra-deep exploration campaigns.
Well Workover and Intervention
Our dual-purpose land drilling rigs are extensively used for heavy workover operations: pulling and running tubing, fishing broken tools and drill strings, milling obstructions, sidetracking stuck bottomhole assemblies, and plug-and-abandonment operations. ZJ40 can handle workover depths up to 10,000 m.
Water Well Drilling
For rural water supply projects, agricultural irrigation, municipal water systems, and industrial water supply wells, our lighter ZJ10 and ZJ15 truck-mounted land drilling rigs are ideal. The self-contained design eliminates the need for support vehicles on small-to-medium diameter wells.
Geothermal Energy Development
With reliable depth capacity up to 9,000 m on our ZJ90D modular rig, plus robust mud circulation systems and all-weather packages for high-temperature environments, SJ land drilling rigs are well-suited for geothermal gradient drilling and production well installation.
Coalbed Methane (CBM) Drilling
SJ offers dedicated CBM land drilling rigs for 1,000 m to 2,000 m depth ranges, designed for the unique requirements of coalbed methane extraction.
Remote & Infrastructure-Limited Locations
When the last paved road was 200 km behind you, a self-propelled land drilling rig that can drive itself onto location is essential. Our truck-mounted rigs have drilled in jungle environments, mountain terrain, desert outposts, and arctic tundra.
