电阻率测井径向局域化的一种实现方法

A Method to Realize Radial Localization Measurement in Resistivity Log.

介绍一种在径向上实现电阻率局域化测井的方法。利用两种常规的深浅电阻率测井资料，采用电阻率反演处理技术，在纵向上多层、径向上有侵入带和原状地层两维电阻率剖面的地电模型中，实现了电阻率测井的局域化测量，对将来自由选择范围局域化测井的实现具有一定的参考价值。

The key to the realization of localization measurements in resistivity log lies in freely selecting the radial measuring range. A 2D geoelectric profile model is designed in which there are radial invasion zone and radial undisturbed zone. Under existing technological conditions, localizable measurements have been achieved in the 2D resistivity profile by inversion technique based on conventional deep/shallow resistivity log data, which not only provide reliable proof for oil gas identification but also lay the foundation for further application of log data.
