Polyacrylamide dry drilling
1. Properties and Utilization
Polyacrylamide (codenamed PAM) Appearance white powder or granules. Mainly for non-dispersed low solids polymer water-based drilling fluid flocculant, has a strong ability to inhibit the mud. Can improve the drilling fluid rheology, reducing friction, etc., without affecting the slurry viscosity and strong under suspension, for 24 hours almost no density difference, shear thinning effect is good, the cake sticking coefficient low; able to maintain the drilling fluid density, a thickening effect, can adjust the flow and the role of some fluid loss, and has a leak-proof sealing effect.
