Tubing friction reducer










Image Number 4 for United States Patent #5692563.

A tubing friction reducer is mounted on a length of tubing within a bore hole. The friction reducer includes a cylindrical body having a first section and a second section hingedly secured around an exterior surface of the coiled tubing, the cylindrical body having an outside diameter larger than an outside diameter of the coiled tubing and less than an inside diameter of an adjacent bore surface. A plurality of roller bearings positioned on and extending outwardly from the cylindrical body extending in a generally axial direction along the cylindrical body for the purpose of reducing friction between the coiled tubing and the bore surface generated upon contact between the coiled tubing and the bore surface. Retaining mechanisms such as collapsible springs are included for securing the roller bearings to the cylindrical body. The tubing friction reducers are placed along the tubing at intervals to either minimize injector force, prevent buckling, and tubing failure, due to buckling or wear.
