| Abstract | A sealed bearing pack (called the Bearing-Seal Package) is being developed for use with downhole mud motors and turbines for geothermal applications. The Bearing-Seal Package contains a sealed lubrication system which allows the bearings to operated in oil instead of abrasive drilling mud. the key to the success of the lubrication system is the development of a reliable rotary seal that will operate under downhole conditions. The development program emphasizes extensive laboratory screening tests of candidate high temperature seals and lubricants. A Seal Test Machine has been constructed to test candidate high temperature seals under simulated downhole conditions. Descriptions of the Bearing-Seal Package and Seal Test Machine are presented. Candidate high temperature seals and lubricants are reviewed and seal tests are discussed. |
