摘要： A downhole tool assembly is configured for repeated and selective hydraulic actuation and deactuation. A piston assembly is configured to reciprocate axially in a downhole tool body. The piston assembly reciprocates between a first axial position and second and third axial positions that axially oppose the first position. The downhole tool is actuated when the piston assembly is in the third axial position and deactuated when the piston assembly is in either of the first or second axial positions. A spring member biases the piston assembly towards the first axial position while drilling fluid pressure in the tool body urges the piston assembly towards the second and third axial positions. Downhole tool actuation and deactuation may be controlled from the surface, for example, via cycling the drilling fluid flow rate.

摘要： A downhole tool assembly is configured for repeated and selective hydraulic actuation and deactuation. A piston assembly is configured to reciprocate axially in a downhole tool body. The piston assembly reciprocates between a first axial position and second and third axial positions that axially oppose the first position. The downhole tool is actuated when the piston assembly is in the third axial position and deactuated when the piston assembly is in either of the first or second axial positions. A spring member biases the piston assembly towards the first axial position while drilling fluid pressure in the tool body urges the piston assembly towards the second and third axial positions. Downhole tool actuation and deactuation may be controlled from the surface, for example, via cycling the drilling fluid flow rate.

摘要： A roller cone drill bit includes at least one relief region 1101 inside the bit body on a ledge 506 formed between a fluid plenum 504 and one of the fluid orifices 502. The relief region 1101 is formed at an angle of between 20 and 360 degrees as determined by rotating clockwise about a fluid orifice axis 502 from a datum plane 601. There may be more than one relief region present (1101, 1301, fig 13) and the relief region may be of a swept configuration (1601, fig 16). The relief region's configuration may be modelled and a fluid orifice entrance area may be at least 20 percent larger than the nozzle entrance area. The relief region may be formed by inserting a machining tool through a fluid orifice.
