摘要
偶极横波、多极子声波测井的商业化应用为油藏勘探提供了重要信息。斯通利波除对裂缝反应敏感外，还对一些特殊的地质构造和地质现象有明显反映，成为评价裂缝的有效手段。在分析裂缝非常发育地层、薄互层、岩性界面、井眼扩径段斯通利波响应特征的基础上，分析了斯通利波形成机理，并对上述地质构造和地质现象的斯通利波响应特征给出了合理解释，为利用斯通利波开展更广泛的储层评价奠定了理论基础。
The commercial application of dipole shear wave and muhipole acoustic log provides important information for oil reservoir exploration. Besides sensitive to the fractures, Stoneley wave possesses positive response to special geological structures and phenomena, so it has become an effective method to evaluate fractures. On the basis of ana- lyzing the response features of the wave in fracture well-developed formation, thin-interbeds, lithological interfaces and hole-size elongated intervals, the formed mechanism of the wave is figured out. At the same time, the reasonable interpretations upon the response characteristics for special geological phenomena have been presented, thus the above results have laid the theoretical basement for more wider reservoir evaluation with the help of Stoneley wave.
