| titleOfInvention | Chemical bonding type relative phase modifier suitable for high-mineralization-degree oil reservoir |
| abstract | The invention disclseos a chemical bonding type relative phase modifier suitable for a high-mineralization-degree oil reservoir, and belongs to the technical field of exploitation of petroleum and natural gas. The relative phase modifier is prepared by performing polymerization reaction on 30-45 parts by mass of acrylic acid, 30-40 parts by mass of acrylamide, 15-28 parts by mass of 2-acrylamide-2-methylpropanesulfonic acid, and 2-10 parts by mass of gamma- methacryloxypropyltrimethoxysilane in an emulsifier-containing water solution at a temperature of 35-50 DEG C for 2-5 h. The relative phase modifier has good high-mineralization-degree resistance, flushing resistance and oil-water selective plugging performance, is capable of having a condensation reaction with silicon hydroxyl on the stratum sandstone surface for generating a new chemical bond at the mineralization degree of 10*10＜4＞ mg/L and at a stratum temperature, forms a multi-layer adsorption film firmly adhered to the stratum, and realizes firm combination with stratum rock. |
