Double-walled RC drill pipe is used for core sampling drilling and
gas lift reverse circulation drilling
Product Description:
This series of reverse circulation pipes can increase the
permeability of the lost stratum, reduce the consumption of
drilling fluid, protect the reservoir stratum, and save the cost of
other consumable tools. In addition, the pipeline can be drilled in
two directions to control the drilling. The reverse circulation
kill method can transfer heavy mud directly to the bottom of the
well without periodic circulation, which saves time.
