2000HP Skid-Mounted Rig

2000HP (ZJ70/4500DB) skid drills adopt swing up substructure and K type mast, one time stringing leads to continuous raising. The double motors and single transmission drive single shaft two shifts AC frequency conversion drawworks, which can realize double stages stepless speed regulation and improve the equipment reliability and operate economically. Electric drive control system of skid drills adopts Siemens PLC and AC frequency conversion technology, which has the characters of high mechanical efficiency and high control precision. The whole rig control system of skid-mounted equipment adopts the redundant heat backup mode which is compatible and fault-tolerant. Being equipped with high pump pressure F - 1600 triplex cylinder mud pump and integrated driller control room, the driller can finish the main operation in driller's chamber.


1. With the adoption of advanced digital AC frequency conversion electric transmission and the integration design of machine, electricity, liquid, gad and digital control, the skid drills are more simplified on structure.
2. Equipment of skid-mounted equipment is installed at low position and integrated hoist,which reduces the workload of aerial work and improve the safety.
3. Electric transmission adopts vector frequency conversion drive system and realizes the fully digital control operation.
4. The reserve interface for remote fault diagnosis expert system of skid drills can realize control parameters and drilling parameters (signal) collection, display, storage, print remote monitoring and management.
5. Enlarging the parameter range of bit pressure, drilling rate, pump pressure and pump capacity realizes the high precise control and improves drilling crafts. With the adoption of frequency conversion technology, the winches of 2000HP skid-mounted equipment are suspended which change the traditional way of driller operation.
6. The high pressure F-1600 mud pump of skid drills can improve drilling speed and ensure the high speed rotation of bit. It prolongs the drill bit's longevity and drilling's working efficiency.
