Abstract

1288081 Boring earth and rock SMITH INTERNATIONAL Inc 8 Oct 1969 49490/69 Heading E1F [Also in Division F1] Drilling apparatus comprises a drill pipe section 4 having bearing means 16, 18 for a rotatable drill bit drive shaft 6 having a bore 26 an inlet 28 and an outlet 30 for conducting drilling mud therethrough, and a rotary pump 40 for delivering drilling mud to the bearing means. The pump comprises a helical rotor 38 and a stator 42 with flexible sleeves 44, 46 held in place by a ring 54. The sleeve 44 defines a bore provided internally with a helical thread having a pitch which is the same as or a multiple of the rotor pitch, the stator being coaxial with the drive shaft. A position of the drilling mud is pumped through the stator sleeve 44 by the rotor to lubricate the bearing means which comprise a thrust bearing 16 and a radial bearing 18. The shaft is connected at the upper end to a rotor or to a flexible coupling 36, and at the lower end to a bit sub 8. The flexible coupling may be connected to a mud operated drive device.
