Abstract
1356294 Boring earth &c INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 28 May 1971 [3 June 1970] 17973/71 Addition to 1219185 Heading E1F In a drilling bit according to Specification 1219185 the zone 5 having a pressure lower than the fluid flow at the inlet 1c is formed by an ejector 3 and a venturi 4. The fluid and cuttings rising through the venturi are whirled by vanes 20 to cause fluid and bulk of cuttings to discharge through orifices 6a whilst the purified fluid discharges through orifices 6b. Most of the purified fluid passes downwardly from the orifices 6b to the working face. In a modification the vanes are dispensed with and the fluid enters the ejector tangentially. A piston 23 (Fig. 3) may be fixed in the bit by pins 34 to permit conversion to a bit having centrifugal flow of fluid over the working face. To convert the flow a ball 36 is dropped down the drill string and the pressure of the fluid shears the pins and displaces the piston, the fluid flowing as indicated on the left hand side of Fig. 3. A fish may be provided for the ball and the pins may be replaced by a spring.
