| titleOfInvention | A kind of water blocking agent and preparation method thereof |
| abstract | The invention relates to a water blocking agent and a preparation method thereof. The water blocking agent comprises the following components in parts by weight: 100-120 parts of acrylamide, 60-100 parts of strength monomer, 10-20 parts of high adhesion promoting monomer, and 0.01-0.1 part of micro-crosslinking agent , 1-4 parts of associative thickener, 40-80 parts of responsive monomer, 2-6 parts of associative monomer, 0-27 parts of potassium hydroxide, 320-400 parts of water, 200-280 parts of oily solvent, 20-40 parts of emulsifier, 2-5 parts of co-emulsifier, 1-5 parts of polymerization stabilizer, 0.02-0.5 parts of initiator, 25-35 parts of phase inversion agent. The water blocking agent of the present invention has a micro-crosslinked association network structure, mainly "intermolecular" crosslinks, dense mesh holes, thicker molecular chains, stronger ability to wrap water molecules, more stable gel, and higher dehydration rate. lower, which can effectively reduce the core permeability and achieve a good plugging effect. |
