| titleOfInvention | Composition for isolating water inflow into well |
| abstract | The invention relates to the oil industry. The purpose of the invention is to increase the water insulating properties while reducing the consumption of reagents. The composition contains the following components in their following ratio, wt.%: Hydrolyzed polyacrylamide 0.15-1.0n n n non-ionic surfactant, soluble in water 0,2-5,0n n n potassium chrome alum 0,003-0,03n n n water the rest. The composition is prepared by sequentially dissolving in water polyacrylamide, non-ionic surfactant and potassium chrome alum in the required ratio. The use of the invention will improve the quality of work to limit water inflows in oil wells and can also be used to regulate the process of flooding of heterogeneous reservoirs. 1 tab. |
