Producing Nanostructure of Polymeric Core-Shell to Intelligent Control solubility of Hidrophilic Polymer during Polymer Flooding Process
First Claim
1. A method of producing nanostructure of polymeric core-shell to intelligent control solubility of hydrophilic polymer during polymer flooding process;
- comprising nanoparticles consisting of two parts, core and shell;
wherein said core is hydrophilic polymer and said shell is a hydrophobic polymer;
wherein said nanostructure is released inside an oil reservoir;
wherein said shell is solvent in oil and said core increases water viscosity;
wherein said shell dissolves in said oil reservoir and decreases water mobility ratio than underground oil in said oil reservoir and further increases efficiency of said oil in an oil removal procedure.

Abstract
Hydrophilic polymer particles have been obtained using polyacrylamide, xanthane, maleic anhydride polymers, allylamine, ethyleneimine, and oxazoline as core polymers. Then, hydrophobic polymers shells have been produced on the core-side using styrene, styrene copolymers, polyvinyl state, polysolfune, polymethyl methacrylate, and polycyclohxyl methacrylate by in-situ polymerization of monomer as method one and inverse emulsion process as method two. These particles can release hydrophilic polymers at oil-water interface at the reservoir temperature where the water flooding should have the maximum viscosity. So, active materials cause to decrease the mobility ratio of water to oil in the reservoirs and on the other hand, plug the swept porosities and prevent to act the water fingering process.
