Abstract
A method and apparatus for automatically testing high pressure and high temperature sedimentation of slurries is described. The method includes pumping a sample drilling fluid into a test cell. The sample drilling fluid may be subjected to a pre-determined pressure and a pre-determined temperature for a pre-determined period of time. The test cell may also be oriented at non-vertical angle. The sample drilling fluid may be pumped out of the test cell and the density of the sample drilling fluid automatically measured relative to a displaced fluid volume of the sample drilling fluid.
Claims7
A method for testing a property of drilling fluids, comprising:
- pumping a sample drilling fluid into a test cell through a first control valve by a first pump in fluid communication with the test cell;
- isolating the sample drilling fluid within the test cell by the first control valve and a second control valve;
- subjecting the sample drilling fluid within the test cell to a pre-determined pressure and a pre-determined temperature for a pre-determined period of time by opening a third control valve to allow a pressurization fluid to be pumped into the test cell by a second pump in fluid communication with the test cell when the sample drilling fluid is isolated within the test cell by the first control valve and the second control valve;
- pumping the sample drilling fluid out of the test cell through the second control valve;
- and
- measuring a density of the sample drilling fluid displaced from the test cell through the second control valve by a density transducer in fluid communication with the test cell.
