Salt-resisting Thinner for Polymer Drilling Fluid--JN-1 |
Salt-resisting Thinner for Polymer Drilling Fluid--JN-1 is a type of vinyl copolymer. Its primary function is as follows:
JN-1 can improve ζ potential of clay, break network structure of drilling fluid, release the wrapped free water, and finally reduce the viscosity and gel strength of drilling fluid.
JN-1 can be used to any water base drilling fluid with the density under 1.5g/cm3 and the pH of 7.5 to 9.0. It can be stable to 180℃.
