Water-lock Inhibitor for Drilling Fluid--- FSS-1
1. Brief Introduction
Water-lock inhibitor for drilling fluid--- FSS-1 is a kind of non-ionic surfactant mainly made from silicon compound and alcohol compound after ethoxylation reaction. The product can be effective in low permeability reservoir during drilling to prevent water blocking damage, so as to protect the low - permeability oil and gas reservoirs .
