Abstract

Poor drillability and hydration expansion is the main difficulties while drilling basalt formation. Drillability and borehole instability of the basalt formation in KL6-4 Block was analyzed in this paper. Field application showed that bit and BHA optimizing and good mud property are the effective measures while drilling through the basalt formation.
