Since petroleum drilling machine came into being, skid-mounted drilling rig has been the basic and most widely used type. Although it is not as easy to be moved as the mobile (self-propelled) drilling machine, skid-mounted drilling machine has flexible structure with steady derrick, powerful drilling capacity and strong adaptive capacity to environment. After AC variable frequency driving is applied into drilling equipment, skid-mounted drilling machine shows more obvious advantages compared with self-propelled drilling machine which has to be equipped with a diesel engine for vehicle running. As the improvement of technology, mounting, dismounting and transport of skid-mounted drilling machine is becoming more and more convenient and efficient.
PWCE can design and manufacture mechanic and electric skid-mounted drilling rig with drilling depth of 3000-9000m (750-3000HP).
The design ambient temperature of the drilling rigs extends from -45°C to +45°C. The systems and equipment can be customized for high temperature, arctic, desert and humid conditions.
The masts and substructures of the drilling rigs are divided into double elevating type, once-raised type, continuous lifting type, bootstrap type, telescopic type, vertical lifting type, box on box type and derrick type, for option of users.
The drawworks can be conventional chain transmission drawworks, or advanced gear transmission drawworks. The auto driller is also for option.
Full digital electrical control system of the drilling rigs has DC and VFD types, any of which can realize the dynamic braking with full torque. The advanced data communication system can realize the remote monitoring function, to improve the efficiency of drilling monitoring and after-sale services.
We can offer a complete set of drilling machine producing the eight major systems. With a high degree of mechanization, this skid-mounted drilling machine can be widely used in various fields and environments.The K-shape derrick which is made of H-shape steel offers an open operating visual field and is easy to be transported. Its design and manufacturing conform to specifications of API 4E, 4F (Specification for Drilling and Well Servicing Structures) and the entire design meet the HSE requirements.
