摘要： A cutting tool (10) for removing members downhole from a well bore and adapted to be inserted within a well from the upper end (12) of the casing (14). The cutting tool (10) includes a plurality of elongate blades (32) on the cylindrical body (18) of the cutting tool (10). Cutting elements (42) of a predetermined size and shape are arranged in a symmetrical predetermined pattern on each blade (32) in side-by-side relation in a plurality of predetermined transversely extending rows and a plurality of predetermined generally vertically extending columns. The cutting elements (42) in adjacent transverse rows for each blade (32) are staggered and have different concentric cutting paths. The cutting elements (42E) in corresponding transverse rows on adjacent blades (32A, 32B) are staggered and have different concentric cutting paths. The blades (32A, 32B) of the embodiment of Figures 7-13 have a separate recess (50) on the leading face (34A) for each individual cutting element (42E) for precisely positioning the cutting element (42E). Each cutting element (42E) has a groove (42K) for receiving and directing forwardly the extending end of a metal shaving (S) to facilitate breaking thereof from the casing (14).

摘要： A cutting tool (22) having elongate cutter arms (36) mounted about a pivot pin (40) for outward swinging movement. Cutting blades (58, 60) are mounted on the lower ends of the cutter arms (36) and have a plurality of closely fitting hard carbide cutting elements (90) secured thereto and forming an inclined leading planar cutting surface (82) inclined from the upper end of the associated blade (58, 60) at an angle A between one (1) degree and twenty (20) degrees relative to the direction of rotation. The cutting elements (90) have parallel rear and front faces (90A, 90B) connected by a peripheral side surface (90C) extending perpendicularly to the parallel faces (90A, 90B). Several embodiments of pivotally mounted cutter arms (36, 36A, 36B, and 36C) are illustrated including various blades (58, 60, 58F, 60F, 116, and 144) having a plurality of closely fitting cutting elements arranged thereon in a plurality of longitudinally and transversely extending rows for forming the leading inclined planar cutting surface.

摘要： A stabilizer (36) mounted on a mandrel (14) of a workstring (12) within a casing (10) of a well bore hole. The stabilizer (36) has an upper carrier (38) fixed to the mandrel (14) and a lower carrier (40) mounted on the mandrel (14) for relative sliding movement. Shoes (70) are mounted by links or arms (64,74) to bearing housings (50, 80) on the carriers (38, 40). The bearing housings (50, 80) are mounted for relative rotation on the carriers (38,40) and permit the mandrel (14) and workstring (12) to rotate relative to the shoes (70) upon fluid actuation of lower carrier (40) and engagement of the casing (10) by the shoes (70).
