Abstract

See full text

A turbine drill motor capable of operation at ultra-high rotary speeds (i.e., in excess of 1000 rpm, which is very high for turbine drill motors), with a high-pressure jet-assist functionality for drilling and well service applications. The ultra-high rotary speed enables fast penetration with diamond bits, while the high-pressure jet-assist ensures adequate cooling and cuttings removal. In an exemplary embodiment, such a turbine drill motor includes a bypass channel to divert a portion of the driving fluid supply when the bit is off-bottom, to limit the no-load runaway speed of the turbine. Serial and parallel flow paths can be accommodated, and different drill bits for cutting and well-bore servicing are disclosed.
