The Truck Trailer Mounted Drilling Rig ZJ20Z (T) is a 2000 meter class trailer mounted mobile land drilling rig complying with API 4F, API 7K and ISO9001 specifications.
The Truck Trailer Mounted Drilling Rig ZJ20Z (T) is a 2000 meter class trailer mounted mobile land drilling rig complying with API 4F, API 7K and ISO9001 specifications. Designed for 1500 2000 m shallow to medium well drilling, completion and workover operations, the whole rig is assembled on a heavy duty semi trailer chassis. It realizes highway towable transportation without full disassembly of main units, and features fast rig up & rig down, high mobility and small site footprint. This trailer type rig is widely used for conventional oil gas, coalbed methane, shallow geothermal, water well drilling and scattered well group projects, being a cost effective mobile drilling solution for frequent well site relocation demands.
Main assemblies including derrick, drawworks, rotary table and power pack are mounted on heavy duty semi trailer frame. The rig can be towed by standard tractor truck for highway transfer; major components remain assembled during transit, avoiding repeated dismantling of large parts and cutting migration preparation time significantly.
Adopts high strength folding derrick with full hydraulic erecting / folding mechanism. No large size field crane is required for derrick standing up and laying down. Auxiliary operation time at well site is shortened, suitable for high frequency shift between scattered well locations.
Adopts mature mechanical transmission as standard configuration, delivering stable lifting and rotary power for 2000 meter well conditions. The system has simple transmission chain, easy on site maintenance and low requirement for well site supporting infrastructure.
Equipped with multi group hydraulic supporting outriggers. After arriving at well site, outriggers extend to provide stable whole machine bearing without heavy concrete foundation, adapting to plain, hilly and relatively flat Gobi well pads.
Key structural members adopt weather resistant anti corrosion treatment; electrical and hydraulic assemblies have dust proof and splash proof protection. Standardized wearing parts facilitate local spare part procurement and rapid field repair in global project sites.

When a shallow-drilling fleet comes up for renewal, operators usually find they are not replacing one rig but several overlapping jobs — a 1500-2000 m oil entry hole, a shallow CBM or geothermal hole, a routine workover pull — and a single towable unit has to cover all of them. The ZJ20Z (T) trailer mounted drilling rig covers exactly that mixed roster: 2000 m nominal depth on 114 mm drill pipe, a 1350 kN static hook load and a 440 kW (590 HP) main drawworks turning a ZP205 rotary table. Everything rides on a heavy semi-trailer frame — derrick, drawworks, rotary and power pack — so a standard haul tractor picks it up and tows it at up to 60 km/h with the assemblies left assembled, and the hydraulic folding derrick goes up without a field crane.
Before you ask us to quote a ZJ20Z (T), send three things that actually change the spec: the axle and bridge weight limits on your haul roads, because the multi-axle trailer and its tractor are configured around them; whether the programme leans more to drilling or to workover, since the 25 MPa standpipe and mechanical drive can be ordered with or without hydraulic assist; and the coldest recorded temperature at your pads, because the standard -30 C operating envelope sets where an alpine cold-start package becomes the safer buy.
Quotations include a delivered scope — rig, power, mud and solids control, and spares — so the number you compare is the number you pay. Tell us your well list and we will confirm whether this 2000 m-class towable is the right match, or point you toward a lighter or deeper family unit first.
Optional low temperature cold start package for alpine areas; dust sand sealing improvement for Gobi sites; multi layer salt spray anti corrosion coating for coastal working conditions.
Adjust trailer axle, braking system and lighting assembly to satisfy road certification requirements of different countries and regions.
Support optimized power matching, auxiliary hydraulic system upgrade for improving operating smoothness under variable load drilling.
Reserve installation interfaces for drilling parameter monitoring unit, fault alarming module and auxiliary pipe handling attachments.
Custom equipment painting, customer brand logo marking, project specific spare parts package and full cycle technical after sales support are available.
