摘　　要：目前大庆油田拥有多个投入生产的二氧化碳驱油试验区,但由于二氧化碳流体在井下以超临界流体的形式存在,同时具有较强的腐蚀性,对仪器设备损害较大,缺少相关防二氧化碳腐蚀的仪器,不能有效进行注入剖面测井。针对这种现状,通过二氧化碳腐蚀性试验,优选了防二氧化碳腐蚀材料,利用氧活化测井方法克服了由于二氧化碳流体的特殊性带来测试难题,改进脉冲中子氧活化仪器,并且建立了氧活化二氧化碳驱注入剖面相关的解释方法。在二氧化碳注入井开展了大量的现场试验,取得了较好的效果。There are a lot of CO2 flooding production test areas in Daqing Oilfield. The injection profile logging can not be carried out effectively due to lack of relevant anti CO2 corrosion instrument because CO2 existed in the form of super critical fluid underground with strong corrosive damage to the equipment. In view of this situation,the anti CO2 corrosion material is optimized out by means of CO2 corrosion test.Using oxygen activation logging method to overcome the particularity of CO2 fluid result in test problem,the pulse neutron oxygen activation tool is improved and the oxygen activated CO2 injection profile interpretation is established related to the method. A lot of field tests have been carried out in CO2 injection well with good results.
