摘　　要：通过对聚合物和交联剂的筛选,制得了适合高温高盐低渗透区块堵水调剖的改性酚醛凝胶堵剂,耐温能力为80～100℃,耐矿化度在40 000 mg/L以上,对岩心封堵率在95%以上,同时具有较好的注入性能。截至2010年11月,在胜坨油田T143区块3口井中应用该堵剂,累计增油2 899.2 t。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.
