摘要
As the design of Hole Ⅱ of the Wenchuan earthquake fault scientific drilling project changes, it is required to down an active casing into the hole from 0 to 311 meters and to fill some fluids into the annulus. Through simulation experiments, the viscious properties of three filling fluids are studied, and their viscosities under the corresponding state is calculated and determined. Finally, the concentration of 2% hydrolytic polyacrylamide (PHP) solution it determined as the filling fluid in the active casing annulus.
