1500hp Bohranlage

ZJ50/3150CZ Skid mounted drilling rig1. ZJ10 ZJ70 RIG 2. Electrical driven 1500hp drilling rig 3. Mechanical driven 1500hp drilling rig 4. SCR DC driving system 5. 1500hp drilling rig VFD system Features of 1500hp drilling rig. 1- Key mechanical parts conform to API spec and marked with API monogram 1500hp Drilling rig 2- Powered by 4 parallel 2000 (3000) series diesel engines + hydraulic torque converter (coupling) + chain box drive 1500hp Drilling rig 3- Drawworks drum is grooved. The main brake is hydraulic disc brake and assistant brake is electromagnetic eddy current brake. Drawworks adopt pneumatic tube clutch for remote control, operating easily and quickly. Drilling rig 4- Drawworks adopts split type arrangement and installed above and under the drill floor. Heavy main drawworks is placed at lower position. Drill floor is box-on-box type structure, compact, easy to rig up. 1500hp Drilling rig 5- Rotary table is independently driven by AC VF motors for 0-240 r/min stepless speed regulation thus eliminating rotary table and mud pump power conflicts which occur in uniform driving system of mechanical rig, thus satisfying quick drilling. AC is provided by auxiliary generator set. 1500hp Drilling rig 1500hp drilling rig specificationMain specification1500hp drilling rigDrilling Depth. m(ft) with 4 1/2” drill pipe1500-16400ft, 3500-5000M (4 1/2 DP)Max.
