Detailed Product Description

drilling rig of ZJ50/3150D(DB)

Features

--the rig is applicable to 2800-4500m drilling depth for oil well with 127mm drilling pipe, and 3500-5000m drilling depth with 114mm drilling pipe

--AC-SCR-DC power transmission system is applied for ZJ50D(AC-DC-AC FOR ZJ50DB@single drum shaft drawworks). through step-less speed control to drawworks, rotary table and mud pumps, user can acquire expected drilling performance.

--grooved drawworks drum with air clutch to shift speed

--disc brake is applied as main hydraulic and auxiliary brake is eddy current brake or eaton brake

--rotary table is driven independently or compoundly

--substructure type of sling shot allows mast and floor equipment installed at low height level then raised integrally utilizing drawworks power or individual hydraulic winches devices

--major components of rig conform to API specification and are allowed to use API monogram

landing drilling rigs
