In this paper, radial investigationdepth of acoustic logging is researched with the well that is surrounded by the cylindrical multi-layer media.
根据这些曲线的变化,简单分析了声波测井的探测深度。

ALL can provide 4 logs that have different investigationdepth. They can be used to inverse invasion radius, invasion zone resistivity and virgin zone resistivity.
So, the investigationdepth of spontaneous potential logging is the depth of mud invasion, and relation between spontaneous potential and mud invasion depth may be built.
