| 摘 要： | 各向同性介质的背景上因存在定向排列的裂隙而导致方位各向异性。描述方位各向异性介质的主要参数是裂隙密度和裂隙的发育方向。同时．裂隙内所含的矿物成分(流体或气体)对各向异性也有一定的影响。以Hudson理论为基础。给出裂隙介质地质模型．通过数值计算．结合理论分析，描述裂隙密度、裂隙的发育方向和裂隙内的流体及气体对纵波传播速度和衰减的影响。为利用纵波属性的变化进行裂缝油气藏的检测建立理论依据。

| Abstract: | Azimuth anisotropic medium is caused by the existence of directional arrangement of fractures on the background of isotropic medium. The key parameters of anisotropic medium being the fracture density and growing direction of the fractures are described, at the same time, the mineral components (fluid or gas ) containing in the fractures influence on the anisotropy for certain degree. Based on Hudson Theory, a geologic model is established for the fracture medium, through numerical calculation the effects of fracture density, its growing direction, fluid and gas in the fractures on compressional wave transmission velocity and its attenuation are presented, by which a theoretical basis is provided for detecting fractured reservoirs by using compressional wave attribute changes. |
