RC Rods Remet Drill Rods For Reverse Circulation Drilling
Depth: 300-5000 m
This series reverse circulation pipes can increase penetration in lost-circulation formation, reduce driling fluid consumption, protect reservoir stratum and save the cost of other consumption tools. ln additional, the pipes can be worked in two direction circulation drling ways to control the well driling. By reverse circulation method to ki the we the heawy mud can be transferred directly to the bottom of well, no periodic circulaton and save time.
