Abstract
There is disclosed a battery system to be used in downhole application. The battery system provides energy to operate the measurement devices associated with drilling. The system includes a plurality of cells, each comprising an electrically insulating mandrel which is shaped to fit over an inner tube, and a combination of an anode, a cathode and a solid polymer electrolyte, all disposed over the mandrel. The individual cells are mounted end to end and are interlocked together to prevent rotation of the cells relative to one another. The cells are electrically connected together and they are all mounted between an inner and an outer tube.
Claims19
Battery system to be used in downhole application, having measurement means, said battery system being adapted for providing energy to operate said measurement means, and comprising
- an inner tube,
- a plurality of solid polymer electrolyte cells,
- each cell comprising
- an electrically insulating mandrel shaped to slidably fit over said inner tube,
