脉冲中子氧活化测井方法是一种能测定井下水流速度的方法,在注入剖面的测试中测得的是分小层绝对注入量。适用于地面油、套分注井、偏心配水器井下分注井、存在大孔道地层的井及注聚合物井的注入剖面测试,还可以用于油、水井的查窜、找漏。因此,脉冲中子氧活化测井技术在油田注入剖面监测及油、水井查窜、找漏等工作中将发挥着越来越重要的作用。
The pulse neutron oxygen activation logging method is a method that can determine the velocity of the downhole water flow. In the injection profile test, the absolute sub-layer injection amount is measured. It is suitable for the injection profile test of ground oil, casing injection well, eccentric water distributor downhole, well with large pore strata and polymer injection well. It can also be used for oil channel and water well channeling and leakage detection. Therefore, the pulsed neutron activation logging technology will play an increasingly important role in oil field injection profile monitoring, oil and water well inspection, leakage detection and other work.
