ARRANGEMENT FOR REMOVING DRILL CUTTINGS IN CONNECTION WITH WELL DRILLING IN THE SEA BOTTOM

摘要

A discharge conduit (58) removes drill cuttings from a control pipe (25) in connection with well drilling in a sea bottom. The control pipe (25) comprises a pipe extension (31), which is provided with an end stopper member (32) and a laterally directed outlet (at 46) to a separate discharge conduit (58) via an intermediate pressure water-driven suction arrangement (50, 54). The discharge conduit is adapted to deliver drill cuttings and the like directly to a remotely disposed deposit location.
