Abstract
In this paper, the tests are designed for investigation of the effects of the synthesized Al2O3 nano particle prepared by ultrasonic and microwave on the drilling fluid flowing properties. Rheological and thermal properties of drilling fluid with nano particle are surveyed. Nano particles which are prepared with two different methods of ultrasonic and microwave are applied in drilling fluid. Experiments are held in heated tube section for simple drilling fluid and drilling fluid which contains 1% nano Aluminum oxide. Results illustrate on the numerical difference between values obtained from ultrasonic nano drilling fluid and those are obtained from microwave nano drilling fluid. Reynolds number increases (1.38 times), Prandtl number decreases (0.222 times) and Stanton number decreases (0.89 times) using ultrasonic method compares with data which are obtained from simple drilling fluid. Application of microwave method shows 1.34 times increase, 0.223 times decrease and 0.93 times decrease in amounts of Reynolds number, Prandtl number and Stanton number, respectively, compares with data from simple drilling fluid. Just dynamic viscosity decreases about 30% using both ultrasonic and microwave method.
