Drilling Rigs

ZJ70/4500LDB Drilling Rig is suitable for 7000m (23000ft) well with 114mm (4.5in) drill pipe, in which the rotary table is driven by AC frequency conversion independence.
The draw works and mud pumps are driven by mechanical.

Drilling floor zone: includes mast, base, rotary table and independent drive devices, lifting system, wellhead mechanical tools, hydraulic casing stabilizer and dog house, driller’s console.
Engine house power zone: includes three A12V190PZL-3/O diesel engine coupler sets, whole chain box, draw works, power saving generator sets, automatic air compressor sets, diesel engine sets, air source cleaning devices, variable frequency drive, VFD, and MCC control house.
Mud pump zone: includes 2 F-1600 mud pumps, drilling fluids valves, manifold and so on.
Mud processing and water tank zone: includes mud circulation tank, mud cleaning devices, water tanks and so on.
Oil tank zone: includes different types of oil tanks, pumps and lines.

-Three sets of diesel engine coupling and whole chain box are united to drive the drawworks, mud pump, rotary table, automated air compressor and energy saving electric generator.
- Diesel + saving energy generators provide the electric.
- The plate brake with the electromagnetism eddying brake (or Eton brake) is used together with the auxiliary device to the mast.
- 600kW, 400V AC frequency conversion motor drive the rotary table to adjust the speed .
- The mast is K type structure. It can go up and down as one block, and is satisfied for installing a 500 tons top drive.
- The height of drilling floor is 10.5m, and it is assembly with one operation in lower position.
- The Drilling rig could be equipped with VFD and MCC system. VFD is used to control the rotary table motor and automatic bit feed motor.
