中子寿命测井工艺及应用效果

Process and Application Result of Neutron Lifetime Logging

讨论了中子寿命测井解释原理 ,介绍了目前国内出现的时间推移、测注测、测堵测等利用中子寿命测井监测剩余油的测井工艺及解释方法。在不同矿化度地层中的应用实例及应用效果表明 ,这些工艺方法可用于非均质水淹层、开发调整井水淹层及油田界面解释 。

Principles of neutron lifetime logging interpretation are discussed,current domestic logging process and its interpretation procedures of time lapse,logging injection logging,logging plugging logging are introduced,of which neutron lifetime logging is used to monitor the remaining oil Examples and result of application in the reservoirs with different salinity demonstrate that these techniques would be used for interpreting heterogeneous watered out reservoirs,watered out reservoirs of adjustment wells and oil water interface,identifying low resistive reservoirs and special lithology
