摘要
在同位素示踪注水剖面测井中 ,根据注水井中不同的管柱结构、短套管位置、自然伽马基线等因素 ,提出了自然伽马对比法、磁定位短套管接箍对比法、磁定位与自然伽马曲线综合对比法和注水层位残留放射性和同位素曲线辅助校深法等 4种不同的测井资料深度校正方法 ,并阐述了其各自的特点。认为在资料深度校正时 ,自然伽马对比法是普遍适用的 ,磁定位短套管法是最为简单的。为了要准确地进行资料的深度校正 ,应综合运用多种校正方法 。
In isotope tracer injection profile logging, four methods for depth corrections--natural gamma curves correlation, magnetic locating and short casing collar curves correlation, magnetic locating and natural gamma comprehensive curves correlation as well as auxiliary injectedbeds residual radiation & isotope curves correction--are put forward on the basis of different casing strings, short casing positions and natural gamma base lines, etc.. In depth corrections, the first method is common and the second is the simplest. To accurately make depth corrections, several comprehensive methods should be used to meet the requirements of isotope injection profile log interpretations of various wells.
