<p>An apparatus for testing a shear thickening plugging fluid, comprising a cylinder (1) having an inlet (2) with an inlet valve (3) for plugging fluid and an outlet (4) with an outlet valve (5) for plugging fluid, a moveable piston (6) sealing against the cylinder walls, so that the piston by being moved in the cylinder can suck plugging fluid into the cylinder through the inlet (2), and in a retrograde movement can press the plugging fluid out through the outlet (4), a shear valve (7) connected with the outlet (4), which shear valve (7) is adjustable for adjusting a desired shear stress, a means (8, 9) for measuring the pressure drop over the shear valve, a means (10) for collecting plugging fluid that has been pressed through the shear valve, and one or more means for measuring properties of the shear thickening plugging fluid.</p> |
