ST 200 Crawler Mounted Drill Rig Tech Data

ST 200 Crawler Mounted Drill Rig Feature

1.Safe and stable walking mechanism.
2.The center of gravity is low and the ground clearance is large, so that it can cross the rough road easily. Special wheel motor drive has strong climbing ability and low failure rate.
3.Advanced automatic leveling function of crawler and stop brake system not only make the drilling rig run stably, but also greatly reduce the impact of the ground on the drilling rig and ensure the driving safety.
4. The unique anti stripping device has greatly improved the reliability of the drilling truck when walking.
5.Vehicle-mounted diesel engine is adaptable to harsh environment. It can walk freely without external air compressor and is easy to move.

How to deal with quicksand formation?

In case of quicksand formation, the viscosity of drilling fluid must be increased and the bentonite content in the drilling fluid must be increased. Generally, it is required to be greater than 10%. A single seal is added to enhance the wall building property of the drilling fluid. In engineering, by appropriately reducing the displacement and reducing the erosion of convective sand layer, the well section must be closed with thick mud with viscosity greater than 80s before tripping out, so as to ensure the smooth running of drilling equipment and electric logging casing
