摘要： A tubing shoe (10) for use on work strings in well bores as are typically utilised in oil and gas production. The shoe comprises a cylindrical body (12) upon which is arranged a reaming portion (22) including pairs of teardrop shaped raised reaming members (26), each pair being mounted oppositely, in parallel and longitudinally along the body. Adjacent pairs of members provide a funnel (42) for collecting approaching debris and a channel for grinding the debris. A nose (14) may be mounted on the end of the shoe, the nose being eccentric or including cutting blades to assist the shoe in breaking through shale and clay stone bridges. A non-aggressive stabiliser (54) in the form of helically arranged blades may also be located on shoe.

摘要： A tool for reducing torque on work string, eg for gas or oil production, comprises an upper clamp (2), a lower clamp (3) and connection means (4), the three components formed as a unitary structure (1). The tool also comprises bearing means, preferably made from an elastomeric compound, and an annular body (7) (see FIG. 4) held in place over the connection means by the clamps. The clamps may comprise spigots (5) for retaining the connection means. In a preferred embodiment the annular body is in two semi-annular components connected at one end to allow them to pivot, and the other end comprises mating castellations for receiving a fastening pin. The annular body may comprise a number of replaceable wear pads (14) which may be made of bronze or an elastomer. The unitary structure of the tool enhances the integral strength and efficiency of the clamps.
