ZJ40 Drilling Rig

1.ZJ40/2250 D/DB/L/LDB Skid mounted drilling rig 2.drilling depth:2500-4000m 3.Max.hook load:2250KN 4. API standards

ZJ40/2250 Drilling rig has four choice of driven mode according to your requirement: mechanical driven, combination driven, DC motor driven, AC stepless variable frequency driven.

Main components/parts,such as a crown block,traveling block,hook,swivel, rotary table,mast & substructure are in compliance with API standards, and can be stamped with API monogram.

Design features:

1.Adopting digital-control technique, computer technique and integrating mechanics, electricity, hydraulics and pneumatics into design, the intelligent control for drilling rig is realized through PLC technology and touch screen.

 2. To reduce driller and drilling workers' labor intensity and promote the drilling automation, the drilling rig is equipped with a hydraulic disc brake and some mechanized wellhead tools to realize the remote control. For electrical driven type, the drawworks is equipped with an emergency motor to greatly promote the capacity for handling any accidents.

3. The erection mode of the mast is self-propelled.

4. For combination driven, DC motor driven, AC stepless variable frequency driven. drawworks and drilling floor equipments is installed in low position, the drum of drawworks is grooved. The brake system adopts hydraulic disk brake and assistant brake (electromagnetic brake, or Enton brake, or dynamic brake) together, with simple structure and reliable performance.

 5.as required, drilling floor can be the structure of block assembled or self-propelled.
