Drilling fluid shearometer is used to measure the attract strength between clay particles (static shear), means forces(shear) destroy the unit area space truss in the drilling fluid, the measured beginning shear force and ending shear force means a lot to drilling and hole protection.
Main technical parameters
Item | Description | Technical parameters |
1 | buoy | ID Φ35.56mm(1.4’’),weight 5g |
2 | scale | Scale range0—20Pa |
3 | mud cup | drilling mud level should above scale0Pa(N/cm2), volume 500ml |
Working principle:
to stir drilling fluid well be measured, pour into a cup, under the free sinking of buoy, measurement shear force in one minute. Then inject well stirred drilling fluid into drilling fluid cup, let it rest for 10 minutes, again under the action of buoy, observe its shear.
