Apparatus and method for measuring the characteristics of an oilfield fluid or the like |
摘要 |
A method of determining the shear threshold of a drilling mud consists in placing a detecting head with a spherical surface near to a porous wall, in pouring the drilling mud around the detecting head, in forcing the mud to pass through the porous surface so as to form a mud cake above the porous surface and around the detecting head which has a diameter D, and in measuring both the time required for the mud cake to reach a measurable or pre-determined height, and also the torque opposing rotation of the detecting head corresponding to that height.
