摘要
注入剖面连续相关测井技术主要是用来确定注入井中的吸水剖面,它克服了放射性同位素载体法示踪测井中井下工具沾污、替注时间、投源量、大孔道、管外窜槽等因素对测井资料的影响,也克服了中子氧活化测井方法测量下限高,成本大的缺点,具有广泛的适用性。
The continuous tracer correlation flowrate logging in injection profile is mainly used to determine water injection profile,which can overcome many influences on well logging data in the radioactive isotope tracer logging,such as the downhole tool isotope contamination,injection time,investment quantity,big hole,outside casing channeling.and also can overcome some shortcomings of lower limit and high cost of the neutron oxygen activation logging method, so it has wide applicability.
