摘要： A rock formation drill bit assembly with electrodes includes a drill bit including a hollow portion that extends along a longitudinal axis of the drill bit. The hollow portion extends from a first end to a second end opposing the first end. Cutters as positioned on the first end. The cutters are configured to cut the rock formation resulting in a rock core protruding from the rock formation into the hollow portion. The rock core includes a circumferential surface. Multiple electrodes are positioned within an inner circumferential surface of the hollow portion. The multiple electrodes are configured to apply electrical discharge across multiple locations on the circumferential surface of the rock core. The electrical discharge causes the rock core to fracture.

摘要： A coring apparatus permitting the taking of a non-rotating core sample and testing of same, as by NMR, prior to breakage and ejection from the apparatus. A core barrel is suspended from a rotating outer sleeve by one or more bearing assemblies which permit the core barrel to remain stationary during rotation of the sleeve with attached core bit for cutting the core. A core test device is fixed with respect to the core barrel on the outside thereof to test the core as it proceeds through the barrel. The apparatus optionally includes a directional detecting device such as an inclinometer and a compact set of circumferentially-spaced steering arms for changing the direction of the apparatus during coring.

摘要： A fixed cutting element drill bit is provided with primary cutting elements which are spaced radially from each other across the face of the bit. During drilling, the gap between the cutting elements causes a ridge to be formed in the bottom of the well and the apex of the ridge is removed before reaching the face of the bit. In one form of the invention, the apex is broken off by utilization of the sides of the supports for the primary cutting elements.

摘要： A drill bit for use in drilling a well bore comprises a main drill body adapted to be rotated about a substantially vertically disposed axis of rotation and having therein a duct extending longitudinally along such axis, for supplying a drill fluid under pressure to the well bore. At least one generally circular, rotatable cutting discs are mounted on the outside of the main drill body at equally spaced locations, with the cutting discs each having cutting elements disposed in a ring-shaped array. Each of the cutting discs has an axis of rotation disposed at an acute angle to the vertical centerline about which the main drill body rotates. The axis of rotation of each cutting disc is slightly offset laterally in a rearward direction from the centerline of the main drill body, thus to cause the entire bit to be placed in a non-equilibrium position with the rotation of the main body enabling the cutting disc to be positioned to be particularly effective and aggressive in cutting the well bore.

摘要： An improved earth drilling bit and method that cuts at least one annular kerf ahead of at least one rolling cutter and provides for rock chip removal and bit cooling thereby increasing drilling rate and bit performance. One embodiment of the invention includes a bit body having a lower end forming an annular kerf cutter for cutting an outer annular kerf, an inner drill member positioned concentrically within the bit body having a lower end forming an annular kerf cutter for cutting an inner annular kerf, and at least one rolling cutter mounted to the bit body and extending from the interior of the outer kerf cutter to the longitudinal axis of the drill bit. Other embodiments include a chipway port defined by the drill bit for channeling rock chips away from beneath the bit; baffles for directing and accelerating drilling fluid flow; cutting edges having connecting webbs providing egress for rock chip and drilling fluid; and slots extending along the bit body for reducing surge and swab pressure.
