摘　　要：间苯二酚作为聚丙烯酰胺的优良交联剂已成功应用于油田聚合物凝胶堵水技术。本文综述了将间苯二酚应用于近井地带小剂量堵水作业、地层深部大剂量堵水作业以及地层内就地交联聚合物弱凝胶驱替作业的室内研究和现场应用成果。The crosslinking polyacrylamides by resorcinol/formaldehyde (R/F) precondesate is introduced and three types of PAM gels for different oilfield treatments are presentsed: (1) AM/BMAM copolymer gel crosslinked by R/F precondensate for water shutoff in near borehole zones, which has been put into field uses in Changqing Oil Fields since late 80s; (2) PAM/R/F mixed aqueous solution gellable in a few of days for indepth water control (in study); (3) PAM/R/F mixed aqueous solution becoming weak gel for reservoir flooding (in study).
