摘要: 斯通利波是一种沿井壁传播的声波,当声波脉冲与井壁和井内流体的界面相遇时就会产生斯通利波。近十几年来,由于长源距和偶极子阵列声波仪在测井中的广泛应用和全波形阵列声波测井资料中各组分波的处理分析方法的进步,可将斯通利波分离出来单独研究并应用于测井资料分析。斯通利波技术是评价裂缝及其渗透性的有效方法。

Abstract: Stoneley wave is a kind of guide waves propagating along the liquid-solid interface in well.When a sonic beam strikes the surface of a thick plate immersed in a liquid, a Stoneley wave is generated. Stoneley wave approach is applied on analysis of well logging more and more widely in recent ten years with the introduction of advanced analysis methods for component waves from full-waveform array acoustic log data. The spectrum of Stoneley waves are used to identify the fractured zones and quantitatively calculate the fracture parameters of reservoirs, especially to evaluate the validity of fractures at fracture-type complex reservoir.

Key words: stoneley wave, well logging, research advance and status quo, fracture evaluation
