PAC-HV/LV products are good mud
treatment agents for well drilling and can be used as the
material for well-completion liquid. It has high rate of
slurry-making and shows excellent raising viscosity performance
and a good resistance to temperature (**0degree). It is suitable
to making well-completion liquid with fresh water, sea water or
saturated water. When adding the different amount of CaCl2, the
well-completion liquid has a certain viscosity and lower fluid
loss.
