Product features
Displacement microspheres are composites made of polymer particles of either nanometer or micron size. It can be widely used in deep oilfield regulation and flooding. The microspheres have the characteristics of high temperature resistance, salt resistance and oil field produced liquid sewage resistance. The particle size of microspheres can be as large as nanometer, which can easily enter the micropores of low permeability reservoir and play a deep profile control and oil displacement effect. At the same time, the microspheres have the characteristics of delayed expansion and can enter deeper parts of the formation.
