| Abstract: | A modified phenolic aldehyde gel water shutoff agent was prepared by selecting appropriate pol- ymer and crosslinker. This water shutoff agent can resist the temperature of 80 to 100 ℃ and the salinity of 40 000mg/L or more. The plugging rate for core of this water shutoff agent is higher than 95% , and it has good injection performance. This water shutoff agent has been used in three oil wells in Block T143, and the production of these oil wells has been increased by 2 899.2 t accumulatively up to November, 2010. |
