摘要
大庆油田有限责任公司测试技术服务分公司利用脉冲中子氧活化测井技术在大庆油田成功地实现了注液态CO2井的吸气剖面测井,解决了注液态CO2井吸气剖面测井难题,认识了井筒内的相态变化规律,实现了体积流量与质量流量的转化,并形成了规模施工能力和相应的补充手段,进一步拓展了脉冲中子氧活化测井技术的应用领域。
By applying pulse neutron oxygen activation logging technology in Daqing oilfield,Daqing oilfield company Ltd.Logging & Testing Service Company has successfully achieved gas entry profile logging in liquid CO2,injection wells,which solved the logging problems in liquid CO2 injection wells.So we can understand phase change law in well bore.And this new application makes it possible for us to transform between volume flow and quality flow.It also provides a corresponding supplementary method for large-scale operation.Meanwhile,it further expands the application fields of pulse neutron oxygen activation logging technology.
