摘　　要：针对河南油田YQ区块由蒸汽吞吐转为水驱开发后因窜流通道发育,水驱效率低的问题,开展分层示踪剂监测技术研究,以达到对油藏高渗流通道进行分析的目的。对8种示踪剂进行了地层配伍性实验、稳定性实验和静态吸附实验,筛选出适用于YQ区块监测需求的LX-1、LX-2和LX-3示踪剂,具有在地层中含量少、稳定性好、吸附量小、检测灵敏度高和安全环保等优点。对该区块Y21226井组开展分层示踪剂监测现场试验,结果表明,井组各层渗透率差异较大,存在高渗流通道,采取调剖措施后取得了较好的效果,提高了注水效率。Aiming at the problem of low water drive efficiency due to the development of channeling channel after the development of YQ block from steam huff and puff to water drive in Henan Oilfield,the layered tracer monitoring technology is studied to analyze the high seepage channel of the reservoir.The formation compatibility experiment,stability experiment and static adsorption experiment of 8 tracers are carried out,and LX-1,LX-2 and LX-3 tracers suitable for the monitoring needs of YQ block are selected.They have the advantages of less content in the formation,good stability,small adsorption capacity,high detection sensitivity and safety and environmental protection.The field test of layered tracer monitoring was carried out for well cluster Y21226 in this block.The results show that the permeability of each layer of the well cluster is quite different and there is a high seepage channel.After taking profile control measures,good results are achieved and the water injection efficiency is improved.
