| titleOfInvention | Composition and method of hydrocarbon fluid extraction at underground deposit |
| abstract | FIELD: oil-and-gas industry. n SUBSTANCE: composition for changing the underground formation permeability includes expandable polymer micro particles which comprise hydrophobic polymer with labile side groups. Said micro particles feature mean diameter of non increased volume making 0.05 to 5000 mcm. Said hydrophobic polymers comprises ethers of acrylic acid and comonomers copolymerised with acrylic acid ether and labile side groups are hydrolysable. Proposed invention covers also the method of changing the underground formation permeability including injection of proposed composition into formation. n EFFECT: simplified control over underground bed permeability. n 18 cl, 2 tbl, 11 ex |
