摘要
针对塔里木油田有些注水井配注量和实际注入量相差比较大,长期注水造成吸水层段GR基值严重偏高,井下特殊管柱下低注入量的注水井吸水层段需要精细划分等问题和生产需要,常规固体同位素五参数法和氧活化能谱水流等注入剖面测井存在一定的局限性。而自2013年引进的示踪相关流量测井利用油管中追踪的示踪峰可以准确计量注水量,提高液体同位素的放射性强度克服吸水层段高GR基值的影响,采用连续追踪示踪峰值精细划分井下特殊管柱的低注入量注水井的吸水层段。
Because there is a big difference between allocation injection and actual injection in some injection wells in Tarim oilfield,long-term water injection causes high GR base value in water absorbing layers,special downhole string and low injection rate of injection water absorption layer need to elaborate and other problems and needs.Conventional solid isotop tracing five parameter method and oxygen activation energy spectrum of water injection profile logging has certain limitation.Using tracer peak of the tubing,the related flow logging introduced in 2013 can accurately measure the injection volume and increase isotopic radioactive intensity to overcome high GR base value in water absorption interval.Continuous track tracer peak is used in fine division of downhole string special low injection rate water absorption layer of the injection wells.
