摘　　要：传统的化学暂堵剂在高温低压井中极易降解失效,起不到防漏失保护油层的目的。针对高温低压油田研发出的化学暂堵剂,能有效地对目的层进行暂时封堵,大大降低工作液漏失,减少储层伤害,缩短产能恢复时间。Conventional temporary blocking agent is prone to degrade in high temperature and low pressure well,and loses theprotection from leakage. The chemical temporary blocking agent developed for high temperature and low pressure oilfield can usedto block the target layer effectively,reduce the loss of working fluid,mitigate the damage to the reservoir and shorten the time ofcapacity recovery.
