Such rig models as ZJ40/2250DT，ZJ50/3150DBT/DT and ZJ70DBT are trailer-mounted drilling rigs for the drilling depth of 4,000 to 7,000 meters recently developed by BOMCO.
TECHNICAL FEATURES
v Advanced AC-SCR-DC or AC-DC-AC electric drive technology is adopted;
v The substructure is of modular structure or parallelogram structure to be raised by drawworks or hydraulic cylinder;
v The mast is of telescoping or K-typed where top drive is applicable;
v Power package can be moved by dollies integrally or separately;
v The mainframe can be moved integrally or separately, and the mast can be moved as a whole by wheels;
v Compared to the conventional rigs, the highly-modularized design of this rig reduces the vehicles for rig move by 1/3 ;
v Rig assembly is much easier;
v It only takes 1/4 of the time for conventional rig move.
