摘要
用数值模拟方法分析高频等参数感应测井(VIKIZ)的探测特性,发现它有较强的径向和纵向分辨能力,能提供用于分析地层电阻率径向变化特征包括低阻环带所需的阵列测井信息,且便于对资料进行直观解释;同时它有纵向分辨率极高的高频短源距相位差测量,有很强的识别薄层包括砂-泥岩薄交互层的能力。
The investigation characteristics of VIKIZ (BHKH3 in Russian) has been analyzed by the numerical modeling. VIKIZ has highly vertical and radial resolution and offers array logging information that could be used to describe the resistivity radial distribution directly. For example, the low resistivity annulus is a typical case. VIKIZ provides phase shift measurements with high frequency and short coil separation between transmitter and receivers, so it has high resolution that could be used to distinguish thin bed , especially the thin sandshale interbeded formation.
