摘要： A cable protection device is for protecting a cable running along a tubular body having a coupling having two side edges. The cable protection device has a body for partly enclosing the tubular body circumferentially. The body is provided with a protective portion having an inside, for enclosing a portion of the cable and a clamping portion having a contact surface for close contact with the tubular body, and also having an outside. The cable protection device further has a fastening device including a flexible member for strapping the body to the tubular body and a tightening mechanism for tightening the flexible member.

摘要： A tubular member includes a central axis, a first end, a second end opposite the first end, and a throughbore extending axially from the first end to the second end. In addition, the tubular member includes a first connector at the first end and a second connector at the second end. Further, the tubular member includes a tubular region axially positioned between and axially spaced from the first connector and the second connector. The tubular member also includes a first upset axially positioned between the tubular region and the first connector. The first upset has an internal transition within the throughbore that increases an inner diameter of the throughbore when moving axially from the first upset to the tubular region. Moreover, the tubular member includes a first wear pad integrally formed on the tubular region. An outer diameter of the tubular member is greater along the first wear pad than along the tubular region.

摘要： A method of protecting a nipple profile of a downhole tool that forms a portion of a tubing string and that is exposed to through-tubing completion operations includes securing a single-trip protective sleeve to the tool so that the sleeve covers the nipple profile of the tool during the completion operations and dissolving the single-trip protective sleeve so that it breaks away from the nipple profile to expose the nipple profile for use.

摘要： Downhole tools with a topographical pattern, and anti-balling material over the topographical pattern. The topographical pattern may be defined by at least one of a plurality of recesses extending into a surface of a body of the tool and a plurality of protrusions protruding from the surface. Downhole tools include an insert disposed within a recess in a body, and the insert comprises an anti-balling material having a composition selected to reduce accumulation of formation cuttings on the tools when the tools are used to form or service a wellbore. Downhole tools include anti-balling material disposed over a porous mass provided over the surfaces of the tools. Methods of forming downhole tools include providing anti-balling material over features on and/or in a surface of a body of a tool. Methods of repairing downhole tools include removing an insert therefrom and disposing a replacement insert therein.

摘要： The disclosure relates to a hardbanding removal apparatus and method for use with oilfield tubulars and downhole tools. The apparatus includes a tiltable frame with support arm, a grinding wheel coupled to the support arm, and an idler wheel assembly to supply mechanical feedback to the grinding wheel through the support arm. The mechanical feedback allows the grinding wheel to remove hardbanding accurately and uniformly on tubulars that are eccentric, curved, or have eccentric hardbanding. The tiltable frame enables grinding of tapered sections of the tubular without reorienting the tubular. The method includes removing hardbanding using the apparatus.

摘要： A drill stem element for drilling a well with flow of a drilling fluid around the element and in a direction extending from a drilling well bottom towards the surface, including a member and a coupling mounted for rotation about the member. The coupling includes at least two abutment zones on a wall of the well during drilling, each abutment zone externally includes at least one abutment portion having an outer diameter greater than a diameter of other portions of the element, each abutment zone having a convex rounded shape generated by revolution, each abutment zone being axially remote from at least one other abutment zone. The coupling further includes an intermediate zone between the two abutment zones, an opening being provided between the coupling and the member for the flow of drilling fluid between the coupling and the member forming a fluid bearing.

摘要： A slip component for a downhole tool has a bearing surface that is hard surface treated. The slip component, which can be a slip or other component of a slip mechanism used on a packer, bridge plug, or other downhole tool, is composed of a non-metallic base material, such as plastic, composite, or ceramic. To hard surface treat the slip component, at least the bearing surface is positioned relative to an ion sputtering apparatus. An intermediate layer is first bonded onto the bearing surface by ion sputtering an intermediate material onto the non-metallic base material of the slip component. Then, the bearing surface of the slip component is positioned relative to an electrosparking apparatus, which has an electrode composed of a selected external material for depositing on the slip component. Using the electrosparking apparatus, an external layer is bonded at least on the bearing surface.

摘要： A hard faced surface comprises a metal substrate. Inserts are attached to the substrate as a covering layer on the substrate. Each insert comprises a thermally stable polycrystalline diamond (TSP) body (or polycrystalline diamond or cubic boron nitride) having a plan section, a contact surface and a flat top surface. A boundary coating on the ultra-hard body renders the body wettable by first braze material. A tungsten carbide cap is brazed with said first braze material to at least the top surface of the TSP block. The inserts are brazed to the substrate in a closely packed side-by-side formation with a second braze material that penetrates the gaps between the inserts and between the contact surface of the bodies and the metal substrate. The tungsten carbide caps of the inserts provide a gauge for the hard faced surface, which caps are ground in a finishing step exposing the caps and providing the hard faced surface with a desired dimension including an amount of the thickness of the caps.
