摘　　要：在测井新技术中用于裂缝识别与研究的主要是地层微电阻率扫描成像、声波成像和方位侧向成像等成像测井系列。常规测井技术与成像测井技术结合,不但可以识别裂缝,计算裂缝的几何参数,还能给出裂缝的有效性、发育程度等参数,进一步分析裂缝网络的横向展布情况。给出的实例说明了测井技术在探测裂缝方面的实用性。Logging techniques play an important role in fracture detection and identification. There are various logging methods to evaluate fractures. Resistivity logging, acoustic logging and dip logging are traditonal methods often used for fractures identification. Formation microimager, acoustic imager and azimuthal resistivity imager are three important tools in imaging series. Combining the traditional methods and advanced imaging techniques provides more clear fracture information about identification, orientation, lateral extent and effectiveness, even distribution of a fracture net. We show some successful applications in Shengli Oilfield for fracture detection and identification.
