The Turbine Parameter Study of Down-hole Turbine Generator of While Drilling for Exploring of China Sea

摘要

The author discusses the development of the Turbine Parameter Studyof Down-hole Turbine Generator of Logging While Drilling forExploring of China Sea. He turbine generator is important to providepower to down LWD instruments. Put forward a kind of hydraulicturbine model of high performance and carry out the study of modeling.Perform the analysis the turbine blades model of different parameters inturbulent flow field and optimize the structure of the turbine by usingfluent software. Analyze the conditions of the effect of the flow rate,rotational speed to the turbine flow field. Through ground experimentalresults verify the relationship of flow rate, rotational speed, and loadand turbine generator output voltage. The established turbine model canmeet the output power of improving turbine and ensure its working life.Adopt the field experimental the simulation of the accuracy of theresults.
