Innovative Technology Features
Rapid Mobility & Quick Rig-up Solutions: SJ offers a wide range of rig technologies including truck-mounted rigs, fast-move skidding rigs, electric-drive full-trailer rigs, helicopter-portable rigs, and desert skid rigs.The "BigEasy” AC VFD rig series (BE770/BE550) co-developed with LOADMASTER features a special modular trailer-mounted structure for fast transportation without needing a crane, significantly reducing non-productive time between wells.
Full Range of Drilling Depths: From 1,000m to 9,000m (675-ton max hook load) series covering all drive types—mechanical, AC, DC, and hydraulic.SJ specializes in 1,000–4,000m truck-mounted rigs (market-leading in China) and 1,000–9,000m modular rigs for larger projects.
Adaptability to Extreme Environments: Purpose-built rigs survive extreme weather—5,000m wheel-rail rigs for low-temperature Arctic operations, 2,000m truck/trailer rigs for desert environments, and 3,000m helicopter-transportable rigs for jungle/island operations.
Automated Control & Digitalization: SJ’s PLC and full-digital variable frequency control systems equipped with vector drive technology offer high-precision closed-loop control for traveling block speed and position.Advanced safety features include anti-collision, anti-sticking, automatic deviation correction, energy consumption braking, and precise suspension.
Genuine All-in-One Integrated Solution: Unlike basic component suppliers, SJ delivers complete drilling packages covering everything—complete rig assemblies, drawworks, masts, crown/traveling blocks, swivels, rotary tables, high-pressure mud pumps, and fluid control products.SI also has top-tier cementing and fracturing equipment for a seamless upstream ecosystem.

Application Fields
-
Shallow Reservoir Construction (1,000–4,000m): Efficient truck-mounted rigs specifically engineered for rapid development drilling in shallow gas and oil fields. Perfect for regions requiring frequent short-distance moves.
-
Medium-depth Well Construction (4,000–7,000m): BE series fast-moving skidding rigs preferred for mature field development and extended-reach directional wells.
-
Deep/Ultra-deep Reservoir Exploration (7,000–9,000m): Heavy-duty AC inverter-controlled modular rigs handling extreme pressures and temperatures found in deep-well drilling operations.
-
Complex Surface Conditions: Field-proven designs tailored for deserts (Gobi), low-temperature/tundra, mountainous areas, and jungle terrains.
