The Trailer Mounted Drilling Rig ZJ40DBT is a heavy duty trailer integrated mobile drilling rig intended for 3000 4000 m medium deep well drilling.
The Trailer Mounted Drilling Rig ZJ40DBT is a heavy duty trailer integrated mobile drilling rig intended for 3000 4000 m medium deep well drilling assignments. Designed and manufactured per API 4F, API 7K and ISO9001 international standards, the whole drilling unit is assembled on a reinforced heavy duty highway compliant trailer chassis. Major core assemblies remain connected without full disassembly during site transfer; the rig can be towed integrally by a tractor truck. This rig is widely used for medium deep oil gas, tight gas, coal bed methane and geothermal well exploitation, and it is highly suitable for cluster well operations in remote areas lacking large tonnage lifting equipment.
Derrick, substructure, drawworks and main power assemblies are pre mounted on high strength trailer frame. After hydraulic folding, the whole rig meets road towing specifications, greatly reducing repeated disassembly assembly work when shifting between well pads.
Large bore built in hydraulic cylinders realize on site derrick raising and lowering. External truck crane is not required for rig deployment, cutting auxiliary equipment cost and shortening well site preparation cycle.
Variable frequency drawworks and rotary table deliver stable and adjustable high torque output. It achieves precise weight on bit control for medium deep complex strata, improving drilling efficiency and borehole stability.
Folded outer dimensions are tailored for narrow mountain roads and compact well pads. Modular partition design ensures high structural rigidity without sacrificing cross region transport capability.
Vulnerable wearing components adopt universal oil field standard parts. Trailer suspension, brake and lighting system fully comply with highway transportation regulatory requirements.
