摘要： The subject matter of this specification can be embodied in, among other things, a tool string positionable in a wellbore that includes a spur gear driven by a source of input rotation, a planetary gearbox having an attachment structure to connect to the spur gear. The gearbox includes a central sun gear, a collection of planet gears disposed in a planet gear carrier disposed around the central sun gear, and a ring gear disposed around the planet gears and planet gear carrier. The attachment structure drives a hydraulic pump or electrical generator at a rotational speed different than a rotational speed of the source of input rotation.

摘要： A wireline drilling system for the hydrocarbon exploration and production industry incorporating a drilling cuttings removal system which acts to remove and store cuttings displaced by a drill bit during drilling operations. The cuttings removal system may employ a screw member having a tapered lower portion and a narrow upper portion to transport drilling cuttings to a cuttings basket and distribute the cuttings therein. Embodiments of the invention include an integral tractor to progress the wireline drilling system and provide weight-on-bit, as well as assist in retrieval of the wireline drilling system if the tool should become stuck.
