According to the functional dependence of the response of anisotropic medium upon the fracture dip, the fractures are classified into three kinds: subhorizontal fracture, dipping fracture and subvertical fracture.
根据各向异性介质的双侧向测井响应与裂缝倾角之间的关系，将裂缝分为低角度裂缝、倾斜裂缝、高角度裂缝3种状态。
Secondly, to interpret fractures. Imagery log can identify fractures accurately. Low angle fractures usually distribute on imagery log in the form of dark colored harmonic curve and subvertical fractures manifest dark colored line with small included angle or parallel against hole axis.
其次进行裂缝的解释，成像测井可以准确识别裂缝，低角度裂缝通常以暗色正弦曲线的方式展布在成像图像上，近垂直裂缝则会表现为与井轴夹角很小甚至平行的暗色线条。
