METHOD FOR DETERMINING REAL-TIME DOWNHOLE MUD PROPERTIES WHILE DRILLING |
摘要 |
A method is disclosed for determining the downhole rheological properties of a wellbore fluid. The method includes moving the wellbore fluid through a wellbore tool assembly into a wellbore at a first flow rate. A pressure is measured at a first position proximate a bottom of the wellbore. A pressure is measured at a second position in the wellbore axially separated from the first position. The wellbore fluid is th en moved through the wellbore tool assembly at a second flow rate. Measuring pressure at the first and second positions is repeated, and at least one rheological property is determined from the pressure measurements.
