I. Product Introduction
This product is a new type of fluid loss control agent that is modified and condensed and copolymerized by natural polymers. Its fluid loss control effect is completely superior to conventional natural polymer fluid loss control agents. Its temperature resistance limit reaches 150°C, and the filtration loss after high-temperature aging is lower than that at normal temperature. This product has the advantages of high temperature resistance (150°C), salt resistance, non-toxicity, and low price. Drilling costs and risks can be reduced.
