摘　　要：正交偶极声波测井是一种测量地层岩石声学信息,进而分析地层各向异性的测井新技术,首次在渤海海域NB35-2-8井碎屑砂泥岩地层中应用,不仅获得了明下段主要砂体储层内部的非均质性特征信息,而且还获得了地应力方向和古流向等信息.这些信息的获得,有助于储层的精细描述与评价.The Cross Multipole Array Acoustilog (XMAC) is a new logging technique to capture sonic information of rocks and to analysis their anisotropy. The first application of the new technique to well NB35?2?8 clastic sequences in Bohai Sea has provided several important data, such as anisotropy of sandstone reservoir, in_situ stress distribution and paleocurrent direction in Lower Minghuazhen Formation. These data are helpful to refining description and assessment of the reservoir.
