摘　　要：MPAL多极子阵列声波测井实现了在软硬2种地层中直接提取纵波、横波和斯通利波的测量结果。对MPAL多极子阵列声波测井的测量原理、仪器构成、特点、技术指标、应用情况等方面进行了阐述,根据其测井资料可提取准确的纵波、横波、斯通利波信息;利用波形、斯通利波变密度图、斯通利波幅度衰减判断裂缝发育段,可以得到地层的快慢横波,用来判断地层的各向异性,从而判断最大水平主应力方位、裂缝发育程度及裂缝延伸方向等。The muhipole acoustic array logging is the rapid developing logging methods in recent years. It makes picking up longitudinal wave（P）, transverse wave（S） and stoneley wave in the slow and fast formation come true. This paper set forth the measure theory, instrument structure, characteristic, technical indicators and applications. We can acquire the longitudinal wave （P）, transverse wave（S） and stoneley wave accurately from the logging data. It can estimate crevice developed segment according to waveform, stoneley wave VDL image and stoneley wave amplification attenuation. It also can acquire the formation slow and fast transverse wave（S） and estimate the formation anisotropism. And that concludes the max main stress orientation, crevice developed degree and crevice extend direction etc.
