Abstract
1504918 Spring units LEE-MASON TOOLS Ltd 19 May 1975 [10 July 1974] 21144/75 Heading F2S [Also in Division E1] A drill-string vibration damper comprises a barrel section 10, Fig. 1a, for connection to the drill bit, a tubular mandrel section 12 for connection to the drill-string, a spline assembly 18 permitting relative longitudinal movement of the sections and preventing relative rotary movement, and a resiliently deformable damping element 38, Fig. lb, disposed in a bath of operating liquid in a chamber 109 defined between the telescoped sections. The lower end of the mandrel may be provided with a floating seal 84, Fig. 1c, which equalizes the operating liquid and the down-the-hole fluid pressures. The damping element comprises a series of alternate elastomeric and rigid rings (Figs. 9 to 14, not shown). Restricted operating- liquid passages 22, 37 are provided to control the telescopic movement of the sections. The sections are laterally stabilized by means of rings 45, 67 and 78.
