This thesis presents a new development in the design of Nuclear Magnetic Resonance (NMR) downhole logging tools for the oil and gas industry and operates in a high temperature environment. Two main improvements of this tool is suggested and analyzed in this thesis. They are a new NMR an-tenna containing a Faraday shield placed between the antenna coil and the analyzed fluid and an improved NMR transmitter operating at 175°C am-bient temperature. This is based on multi-module, multilevel topology, which combines the outputs of several identical power modules, which ope-rate at a 50% duty cycle at its fundamental frequency. |
