摘要： A coring bit for extracting a sample of subterranean formation material from a well bore may include a bit body having a bit face and an inner surface defining a substantially cylindrical cavity of the bit body. A first portion of the inner surface may be configured to surround a core catcher. The coring bit may include a face discharge channel inlet formed in the inner surface of the bit body longitudinally at or above the first portion of the inner surface. The coring bit may also include a face discharge channel extending through the bit body from the face discharge channel inlet to the bit face. A tubular body having a core catcher may be disposed in the coring bit to form a coring tool. Methods of forming such bit bodies may include forming an inlet for a face discharge channel in the inner surface of the bit body at a location longitudinally at or above the first portion of the inner surface and forming a face discharge channel extending from the inlet to the bit face.

摘要： A core lifter assembly (12) comprises a combination of a core lifter ring (10) and a core lifter case (14). The ring (10) has an ax!a!!y extending portion (16) of an outer generally frusto-conical configuration having an included taper angle β. The included taper angle β is also the taper angle of the outer circumferential surface (18) of the ring (10). The included taper angle β may in alternate embodiments be ≥ 6°; > T°; ≥ 8°; or ≥ 10°. In one embodiment an upper limit of the included taper angle β may be about 30°. Thus in one embodiment the included taper angle β may be expressed by the relationship: 30° ≥ p ≥ 6°. Further, the angle β may comprise any sub range within the aforementioned range of 6 − 30°. However in other embodiments the taper angle may exceed 30°.

摘要： A core lifter may be used in a drilling system. An exterior surface of the core lifter may include a plurality of longitudinally-oriented recesses. The core lifter may include a raised contact feature that may extend inwardly away from a gripping surface of the core lifter. The core lifter may include a flared skirt configured to limit movement of the core lifter relative to a core lifter case. The core lifter may be formed via stamping a sheet of material.

摘要： A core lifter and method for making same for use in a drilling system. The core lifter can include a tubular body having an exterior surface and an interior surface and can have a plurality of longitudinally-oriented recesses formed in the exterior surface of the tubular body of the core lifter and extending radially inwardly relative to the central axis of the core lifter. The plurality of longitudinally-oriented recesses formed in the exterior surface of the tubular body of the core lifter can extend along at least 50 percent of the length of the core lifter.

摘要： Drilling apparatus is coated on selected surfaces with PTFE. In the drawing is shown an example of the application of the invention to a core barrel assembly. An outer core barrel l0 and an inner core barrel ll are shown which are normally in sections. At the lower end of the outer core barrel there is attached a core catcher sub l3. At the lower end of the inner barrel ll is attached an inner barrel breaker sub l4 and below that a core catcher l5. A core bit l6 is attached to the lower end of the outer barrel. Parts are shown coated with PTFE by thick lines, e.g. the inner surface l8 of the inner barrel ll, the outer surface l9 of the inner barrel and the inner surface 20 of the outer barrel l0. The outer surface 2l of outer barrel l0 may also be coated for example, and the surface 22 of the drill bit, the inner surface 23 of the core catcher and the inner surface 24 of the inner barrel breaker sub.

摘要： An improved coring device that incorporates a nonrotatable inner barrel (50) disposed within the outer driving structure (12) of the drill string which is coupled to the coring bit (30). A woven metal mesh sleeve (105) is circumferentially mounted outside the inner barrel (50) and tucked around its lower end (112). The lower end of the mesh sleeve (105) in the inner barrel (50) is in turn connected to a stripper tube (40) which is pulled upwardly during the coring operation. As the core is cut by the coring bit (30) and enters the inner barrel (50), the woven metal mesh sleeve (105) is disposed about the core and constricts about the core when pulled upwardly by the stripper tube (40). The opposing end of the woven metal mesh sleeve (105) is under a weight (126) which serves to compress the metal sleeve (105) when outside the inner barrel (50), thereby increasing its diameter. The plurality of wedge-shaped segments (125) located on the top of the sleeve (105) are collectively brought together to form a core catcher when that end of the woven metal mesh sleeve (105) to which the segments (125) are connected is drawn around and into the lower end of the inner barrel (50).
