| Abstract: | The AS fluid loss additive was formulated with sodium lignosulfonate and the copolymers obtained by radical polymerization with AMPS and AM as raw material.Orthogonal tests were designed for optimizing the synthetic process of the fluid loss additive AS,and the performance of this fluid loss additive was systematically evaluated.API filtration in saturated salt solution at 150 ℃ is 96 mL;API filtration can be controlled within 50 mL when adding AS between 3% and 8%(weight percentage) at 120 ℃;Meanwhile AS has good compatibility with other additives.Sodium bicarbonate was used to adjust the PH and discharge oxygen of device used in the synthesis process.No nitrogen was needed as protective gas,which simplified the synthesis process.The sodium lignosulfonate derives from the wastewater of paper mill,so it not only reduces the cost but also protects the environment. |
