摘要： Some embodiments of the present invention generally provide an apparatus that may be used in a coiled tubing drillstring and that can switch between effectively straight drilling and curved drilling without halting drilling. Methods for steering a coiled tubing drillstring are also provided. In one embodiment, an apparatus for use in drilling a wellbore is provided. The apparatus includes a mud motor; a housing; an output shaft; and a clutch actuatable between two positions. The clutch is configured to rotationally couple the mud motor to the output shaft when the clutch is in a first position as a result of fluid being injected through the clutch at a first flow rate, and rotationally couple the output shaft to the housing when the clutch is in a second position as a result of fluid being injected through the clutch at a second flow rate.
