Nanocomposites for sand retention screen tunable absorption

摘要

Abstract invention patent: "nanocomposites for sand retention screen tunable absorption".The present invention relates to a downhole filter comprising a foam of open cell include; and nanoparticles prepared in the foam of open cell and exposed inside the pores of the espuMa of the cell open.A method for the preparation of the filter bottom includes combining a poly isocyanate and polyol to form a polymer composition; introducing nanoparticles in the polymeric composition and formation;The composition of the polymer foam to produce the downhole filter comprising an open cell foam with nanoparticles exposed inside the pores of the foam of open cell.The nanoparticles can be derived with functional groups.
