Available in PDF, EPUB and Kindle. Book excerpt: Significant progress was made during Phase I of the program toward finding solutions to the seal-and-bearing problems. A seal-test facility was designed and built to test full-scale seals for downhole motors. The tests will simulate closely the environment imposed on seals used in actual motor drilling. Many seal designs and concepts were considered, including novel designs and modifications to conventional seal types. Several of the most promising designs (including some novel designs) have been designated for testing in Phase II. Some of these seals have already been obtained and are available for testing. The preliminary design for a seal-bearing package test stand was completed. This facility will allow tests of full-size seal-bearing packs at simulated downhole conditions. The design of a new seal-bearing package was completed and is scheduled for full-scale testing in Phase II. This package will allow worn seals and bearings to be replaced easily. New thrust bearings were selected for application in the seal-bearing package. These bearings offer much greater load capacity and should increase bearing life significantly. (JGB).

Available in PDF, EPUB and Kindle. Book excerpt: Research progress is reported in two main sections: downhole drilling motor design and design of downhole motor seal, bearing, and test lubrication systems. Information on downhole drilling motor design is presented under the following subsection headings: Turbodrill development; positive displacement motor development; theory of Turbodrills; theory of positive displacement motors; basic motor components; forces on thrust bearings; thrust bearing design; radial bearing design; rotary seal design; sealed lubrication system; lubricants; and project status. The appendix contains information on high temperature lubricants. Information on the design of downhole motor seal, bearing, and test lubrication systems is presented under the following subsection headings: seal, bearing, and lubrication test design criteria; basic test conditions; independent and dependent variable parameters; alternative concepts for seal test apparatus; design of the seal test system; and bearing test system description. A schedule for remaining tasks is included. (JGB).
