水平井测井解释面临的新问题是地层各向异性的影响，为更好地了解地层各向异性的大小及其对测井值的影响，在实验室建立了测量岩石各向异性的装置和方法。取与水平井同一层段的岩心，按层界面切割出立方体，测量不同方向上参数的变化。所有的砂泥岩样品都显示了在垂直层界方向渗透率最小、声波速度最小、电阻率最大的特征。由此算出岩石各向异性系数，并对水平井电阻率曲线进行校正。
The new problem facing horizontal well log interpretation is the influence of formation anisotropy. To better understand the magnitude of formation anisotropy and its effect on well logging values, a device to measure rock anisotropy was established in the laboratory method. Take the same level of horizontal well core, according to the layer interface cut a cube, measured in different directions of the parameter changes. All sandstone and mudstone samples show the lowest permeability, the lowest acoustic velocity and the highest resistivity in the vertical direction. The rock anisotropy coefficient is calculated, and the horizontal well resistivity curve is corrected.
