Modular Rig Containerized Delivery Configuration

Working condition profile

Remote onshore land drilling programs at 3000-4000 m depth typically begin with containerized ocean freight to a regional port, then inland road transport to a greenfield pad. Oversized, non-containerizable assemblies drive up freight cost, require special transport permits, and delay customs clearance. Two capability tiers are usually needed: a deeper, top-drive rig for the main program and a lighter, quicker rig for infill and contingency wells. Reassembly must be achievable by a mixed crew with standard tools, and export documentation must support customs and the buyer's own quality audit.

Equipment selection

The main rig is the modular land drilling rig SZJ2250M, rated to 4000 m on 4 1/2 inch drill pipe with a 2250 kN maximum hook load, dual 450 kW main drive motors, 800 kW x 2 standard generator sets, and a top drive delivering 45000 N-m low-gear torque. Its 16.2 m top-drive stroke and 6.4 m rig floor deck follow modular land-rig practice, and it supports mud rotary, DTH air, foam, and air reverse circulation drilling.

The companion rig is the skid-mounted modular drilling rig JR-SK3000, rated to 3000 m on 114 mm drill pipe with a 1580 kN static hook load, 560 kW (750 HP) main drawworks, ZP275 rotary table, and a light-duty K-type open-front modular derrick. It can be mechanical, SCR-DC, or AC-VFD driven to match available local power. Both rigs are part of the modular and skid-mounted rigs line.

Configuration & key specifications

Key specifications below are verified against published product data for the two rig models.

Delivery & field capability

Both rigs are engineered to break out into standard container-sized modules so they move as ocean freight without out-of-gauge special handling. The factory prepares design drawings, API referenced certificates, operation manuals, and export documentation including certificates of origin for customs clearance, and reassembly proceeds with standard tools on the pad. The heavier SZJ2250M anchors the main drilling program while the JR-SK3000 provides flexible infill capability; containerized modules let buyers plan the vessel, inland trucking, and reassembly crew on a predictable schedule rather than waiting on abnormal-load logistics.
