Salt-resisting and High Temperature Filtrate Reducer for Drilling Fluid--SJ-1



BRIEF INTRODUCTION

The SJ-1 product is olefin copolymer with medium relative molecule weight. A certain proportion of adsorption and hydration groups to the molecule link, such as –CONH2, -CN, -OH, -COONa, -SO3Na etc., SJ-1 bears good salt-resisting and high temperature stable abilities in drilling fluid. SJ-1 can be used as filtrate reducer in freshwater, seawater and saturated saltwater drilling fluid with the pH of 7.5 to 10. The product can be stable to 180℃
