How to Match the ZJ20L-J to Your Project
For a scattered well group, mobilization cost often exceeds the rig price, and the ZJ20L-J mechanical land drilling rig is engineered to shrink that bill. The L-J take on the classic ZJ20 keeps a diesel-only mechanical drivetrain with no mains dependence — 2000 m on 114 mm pipe, 1350 kN hook, 440 kW drawworks over a ZP205 table — but trims the derrick, box substructure and power skid into road-load units for hilly, restricted pads. Across thin oil rims, coal-seam gas and low-temperature aquifer projects spread over a concession, this is the economic fit. The diesel-only drivetrain needs no pad grid, which is why dispersed rural concessions favour it over an electric alternative; a tight deep cluster calls for a heavier-capacity land unit instead.
Opening a ZJ20L-J drilling rig inquiry is easiest when you describe the move between wells first. Give us the well count, the lowest bridge and axle limit on the route, and whether each pad has mains supply — the mechanical drive runs on diesel by choice, but we tune winterization and dust-sealing kits to the local climate. Note the split between new drilling and routine workover in your budget, since the 25 MPa standpipe and 8-line hoist cover both. The build follows API 4F, API 7K and ISO 9001 across the L-J range; desert, low-temperature and coastal protection are factory options.
There is no off-the-shelf ZJ20L-J price: derrick height, mud pump and electrical standard set the build. Crews can be trained at your site or at our Jingzhou works, which matters for teams moving up from smaller rigs; outline the well count and route limits and we return a commercial outline with the module split.
