Main Features
Combines the advanced technical property of AC VF rig and fast moving property, satisfies the requirements of rapid and easy rig-up and teardown for medium depth well and frequently moving.
The mast and drawworks are transported with a semi-trailer, other component modules are transported with trailer or semi-trailer, it has good deployment performance.
The mast, made of 2 or 3 sections, telescoping, and the substructure are raised hydraulically; they are convenient for assembly and disassembly.
All drive adopts AC VF motor, has advantage of DBS rig. The drilling pump can be driven by diesels parallel operation
High degree of modulization , convenient and easy to move and rig up.
Realize the functions of constant WOB and auto-bit-feeding, and WOB control.
Can be equipped with independent driller cabin, with advanced drilling instruments and reasonable layout, the driller can fulfill all drilling parameter setting in cabin, the working condition be improved and the labor intensity be lightened greatly.
