斜度井的侧向测井围岩校正

Shoulder Bed Correction for Laterolog in Inclined Wells

在不考虑井眼和侵入影响的条件下，仪器轴与深度轴的夹角可从０变到π／２，通过深度坐标与仪器生标的转换关系，利用镜像法可求得仪器主电极位于地层中部时的侧向测井视电阻率响应，以此为基础可研制出斜井侧向测井的围岩校正图版。以双侧向测井（最复杂的一种侧向测井）为例进行数值计算，得出了深、浅侧向测井的校正图版。

In the case of that effects of hole and invaded zone are neglected, angles of the axes of tool and depth can be varied from 0 to π/2. According to the mirror effect method, as well as the relation between the depth and tool-axis coordinates, laterolog responses at the midpoint of a bed can be calculated. Corrections of the shoulder beds forlaterolog in inclined wells can be carried out. The most complicated laterolog dual laterolog responses are simulated and their correction charts are obtained from numerical results.
