USING NANO PARTICLES OF AL2O3 IN DRILLING FLUID TO ENHANCE HEAT TRANSFER

In this study Nano particles of aluminum oxide with 10 Nanometers size have been examined to obtain a drilling fluid with high heat conductivity factor in order to use in extra deep wells’ drilling and Geothermal and it was observed that if volume percentage of aluminum oxide increases by 2.5, heat transfer of fluid will be increased by 40%.Nano particles of aluminum oxide result in no corrosion in mud pumps and drilling pipes due to their Nanometer size. They are always suspended in the fluid, because of Brownian motion and no suspension or sedimentation was observed and they simply rotate in the mud system.
