    摘要: Brine-in-glycol emulsions are shown for use as well working fluids. The fluids have a glycol external phase and a brine internal phase. The separate phases are emulsified to create an emulsion and weighted with traditional weighting agents. The external phase is soluble or dispersible in sea water when diluted upon discharge.

    摘要: The invention relates to an adaptor for drilling strings. The adaptor comprises a body (16) having a head screw-threadably mountable on the lower end of a drilling string, having at least one intake passage (19) extending substantially radially through the body and arranged to communicate with a pressure pipe in the drilling string; a sleeve (23) rotatably mounted on the body and longitudinally movable relative thereto; a mount­ing block (26) mountable on the lower end of the sleeve and movable therewith relative to the body and arranged for connecting to drilling equipment and having at least one air intake passage connectable with an air intake port in the drilling equipment; and air passage means between the intake passage defined between the body and the sleeve arranged to connect the intake passage in the body to the air intake passage in the mounting block. The adaptor is so arranged that in a first position of the sleeve relative to the body, pressurized air from the pressure pipe is directed through the intake passage in the body, the air passage means (33) and the air intake passage (32) in the mounting block to the air intake port of the drilling equipment; and in a second position of the sleeve relative to the body, the pressure air is directed by the intake passage (20) to the drill hole above the adaptor to clear debris from the drill hole.
