XJ1200(225T) workove rig

Detailed Product Description

 Road construction cost for mountainous oil and gas field is very high, therefore, the road conditions are always bad. It is usually difficult to transport the conventional workover rigs to the mountainous oilfield, since they are limited to the conditions for gradient, turning radius, weight, height and width.

    XJ1200(225T) workove rig, specially developed for Puguang gas field, is mainly composed of truck-mounted main unit, derrick, substructure, mud purification system, mud pump room, generator sets and oil tank area. It combines the advantages of modular rigs and self-propelled rigs. The space needed for installation of the derrick is less, and the derrick will be transported after dismounted to several modules.

main features:
     small size, less turning radius, lightweight, higher gradeability 
     Mast split into six sections, detachable for transportation 
     Bootstrap mast, less installation area needed 
     Main brake (hydraulic disc brake) and auxiliary brake (Eaton air-controlled water-cooling disc brake) are safe and reliable 
     Hydraulic, air and electric controls are centralized in DCR 
     Less time is needed for movement and installation 
     Suitable for installation of a top drive device.
