Physical Properties of Drilling Fluids at High Temperatures and Pressures

摘要: Rheological and dynamic filtration properties are presented for water- oil-based drilling fluids. The physical were obtained at test temperatures to 400{sup 0}F (478 K), system pressures 15,000 psi (103 MPa), differential pressure 600 (4.1 MPa). data indicated that the de Guzman-Andrade law can be used describe temperature effects on viscosity of oil muds. authors also observed rates fluids greatly affected by solids plugging pore space in formation. Temperature affect changing dispersion fluid.
