Abstract

A device for protecting and securing small diameter tubular members along a pipe string in a wellbore is disclosed. The protector is designed to fit about the joints of connecting pipe sections and comprises a sleeve assembly capable of being arranged and locked about a pipe joint. The sleeve assembly preferably comprises a plurality of symmetrical, most preferably semi-cylindrical, sleeve members having interfitting longitudinal end portions, preferably held by hinge pins in circular arrangement about a pipe joint. At least one longitudinal channel is formed, preferably with a pair of parallel, longitudinal ridges on the interior surface of the sleeve assembly to receive and hold therein a small diameter tubular member. The sleeve assembly is further characterized by shoulder members spaced sufficiently far apart to bracket the greater diameter pipe joint to prevent longitudinal displacement of the sleeve assembly with relation to the pipe string and joint. Preferably, the channel includes a biasing device, most preferably a resilient or elastomeric material, to bias the tubular member against the pipe joint to prevent longitudinal and transverse movement relative thereto. Preferably, the ends of the sleeve members are formed to project inwardly, most preferably at 45 degrees, to provide both annular shoulder members and a smoother transition between the end of the sleeve assembly and the adjacent pipe section to prevent hanging in the borehole.
