摘要： A well tool can include sealing surfaces, and a shape memory material seal which dynamically seals between the sealing surfaces with metal-to-metal contact between the shape memory material seal and each of the sealing surfaces. A method of sealing in a well tool can include forming a shape memory material seal, heat treating the seal, then deforming the seal, then installing the seal in the well tool, and then heating the seal, thereby causing the seal to expand into metal-to-metal sealing contact with a sealing surface which displaces relative to the shape memory material seal. A drill bit can include sealing surfaces formed on a cone and a journal of the drill bit, and a shape memory material seal which dynamically seals between the sealing surfaces with metal-to-metal contact between the shape memory material seal and each of the sealing surfaces.

摘要： A drill bit (10) for rotary drilling of a borehole has a body (12), a cutting insert (32) at its front end (11), and one or more fluid passages (52a, 52b, 54a, 54b) leading to outlet apertures (56a, 56b, 58a, 58b). The outlet apertures are situated at tapered side surfaces (18a, 18b, 19a, 19b) which may range from a steep obtuse angle to a reflex angle inclination relative to the forward direction. The outlet apertures may be provided in pairs (56a, 58a) which are both axially and angularly offset, so as to assist flushing of drill cuttings from the cutting surface and back along the borehole. The cutting insert (32) may be generally chevron-shaped, with a trailing surface (44) raked back relative to the direction of drilling rotation, matching an angled trailing surface (36) of a groove (30) for locating the cutting insert (32).

摘要： A system 20 for a drilling and fracturing a wellbore 22 in a single trip includes a drill string 26, drill bit 40, and a fluid flow means for delivering fluid through the string and drill bit 40. The drill bit 40 includes a body with cutting blades 42. and nozzles 46 between the cutting blades 42 for washing away drilling generated cuttings. A packer 62 on the drill bit 40 selectively seals with an inner surface of the wellbore 22 to form a space 64. Deploying the packer 62 at a designated spot in the wellbore 22 defines a fracturing zone Z in the wellbore 22. Closing the nozzles 46 while opening side ports on the body, delivers fracturing fluid into the space 64, A pressurizing system 20 can be included to pressurize the fluid so that pressure in the space 64 overcomes the formation strength and fractures the formation adjacent the enclosed space 64. The packer 62 can be released, drilling can resume, and fracturing can occur at a different depth in the wellbore 22.

摘要： The invention relates to a method for down-the-hole drilling, the drilling being carried out by an apparatus, having a drilling device (1) that comprises a casing part (2) and at least during a drilling situation an essentially inside thereof existing drilling unit (3), at the drilling head of which there are at least first drilling means (4) for drilling a center hole, second drilling means (5) for reaming the center hole for the casing part (2) and a pneumatic flushing flow arrangement (6) for leading of drilling waste by influence of pressurized air at least partly upward, whereby the first drilling means (4) are coupled with the second drilling means (5) first of all power-transmittedly in order to carry out cooperation thereof at least during a drilling situation with the second drilling means (5) for a rotational motion (w4), a feeding motion (z4) and/or a hammering motion (t4), and on the other hand removably in order to enable removal thereof from the hole. Furthermore the casing part (2) is arranged to be drawn into a hole to be drilled by the drilling unit (3). Particularly direct aiming of a flushing air flow (HV) at the soil is being prevented by directing the flushing air at an end of the drilling unit (3) into a counterpart surface arrangement (X) on the drilling surface (Pl and/or P2) existing of the first and/or second drilling means in order to decrease kinetic energy of the flushing air flow (HV) by changing its flow direction on the drilling surface prior to drifting thereof into the ground. The invention relates also to an apparatus applying the method.
