摘　　要：聚合物凝胶类堵剂被广泛应用于各大油田调剖堵水作业,取得了较好的应用效果。但如何实现深部运移和封堵,注入水高效波及,一直是研究热点和难点。本文针对海上油田开采特点,通过室内配方研究与物模实验评价研究,得到一种深部液流转向剂ZXT-01配方(聚合物0.3%~0.5%+交联剂0.05%~0.10%+稳定剂0.2%~0.3%+促胶剂0.005%~0.02%;各药剂加量为质量百分数)。通过控制体系成胶时间和强度,实现深部运移与封堵。2012年6月~2013年11月应用于QHD32-6油田6井次,注水压力平均提高1.9MPa,受益油井增油降水效果明显,累计增油40283m^3,累计降水75354m^3。The polymer gel plugging agent is widely applied in various fields for profile control and water shutoff operation,good results have been achieved.But how to achieve deep migration and plugging,and achieve injected water effective spread,have been the hotspot and difficulty.According to the characteristics of offshore oil exploitation,through the experimental study on evaluation and research of the indoor formulation mode,adeep fluid diverting agent ZXT-01formula（polymer 0.3 %-0.5%＋crosslinking agent 0.05%-0.10%＋stabilizer 0.2%-0.3%＋promoting gel agent 0.005%-0.02%）was obtained.Deep migration and plugging were achieved by controlling the gelling time and strength of systems,it was used in 6wells of QHD32-6oilfield from 2012 June to 2013 November,and the application effect was obvious,the water injection pressure increased an average of 1.9MPa,the cumulative incremental oil was 40283m-3.The cumulative precipitation was 75354m-3.
