摘　　要：针对胜利油田长期以来长岩心评价实验由于核心部件的技术指标限制导致实验无法开展的问题,对国产设备HBCD-50型长岩心评价流程的岩心夹持器和回压阀进行重新设计。通过重新优化设计,有效地克服了原流程的操作性差、出口计量不稳定的难题,实现了有效利用天然岩心进行模拟试验的目的。改造后的设备在胜利油田重点实验室课题《高温高压低渗透砂岩油藏伤害机理研究》中低渗透油藏的酸化、水锁评价方法研究中发挥了巨大作用,为模拟研究油藏条件下低渗透砂岩损害机理提供了室内依据。To solve the problem that the long-core evaluation experiment of Shengli oil field can not be carried out because of core component's technical indicators restricted for long time,we redesigned the core holder and the back-pressure valve of long-core evaluation processes,which type is HBCD-50.By re-optimizing the design,we overcame the problems in operation and the instability in export metering of original process,so that the natural core can be effectively used for the purpose of simulation experiments.The equipment played an important role in the evaluation of acidification and water block of low permeability reservoirs,and provided a room basis for the simulation of low permeability sandstone damage mechanism under reservoir conditions.
