How to Match the ZJ40J to Your Project
A 735 kW (1000 HP) diesel-mechanical drive line answers a power-infrastructure problem no electric rig can: it brings its own power station to a pad that has none. The ZJ40J is our medium-deep 4000 m-class mechanical drilling rig, rated for 4000 m on 114 mm pipe, a 2250 kN static hook and a ZP375 rotary table. Driven by a high-power diesel cluster through an all-mechanical transmission, it delivers steady torque through 3000-4000 m holes in tight gas, coalbed methane and medium-depth geothermal programmes where grid-reliant electric units would wait on substation upgrades. The heavy-duty mast and box-style substructure are sized for long-cycle heavy-load work, and the enclosed operator's cab keeps the driller out of dust and weather.
Tell us three things when you inquire: the formation profile and expected string weight at total depth, the fuel quality and altitude the diesels will actually run on, and whether the job will include medium-deep workover alongside drilling. The 32 mm wireline on 6 x 7/12 lines, the 35 MPa standpipe pressure and the -35 C to +55 C range are standard, with API 4F, 7K and ISO 9001 certification across the fleet. Because this unit is mechanically driven, it is unaffected by grid-voltage fluctuation - but if your lease already supplies reliable three-phase power, comparing it against the electric ZJ40D is worth doing before you commit.
Our engineers will confirm the delivered configuration in writing before the order is placed, so the quotation you approve is the machine you receive - including the diesel brand, the pump package and any dust or cold-environment packs. Every module is checked against shipping dimensions before fabrication, with pricing built around the engine cluster and pump selection.
