| 摘 要： | 岩石的各向异性与油气的运移和储集有着密切关系.在油气勘探和油气田开发中，横波对各向异性的敏感性具有重要价值，它可提供一些其他方法无法获取的新信息.纵波在地下传播时，当通过路径的岩石存在各向异性时，会在波阻抗界面产生纵波和横波.这相当于纵波震源同时激发出纵波和横波，利用这些信息就可以对地下岩石的物性进行研究.本文以有限差分为基础，以地下油气田的储藏地质特性为对象，利用弹性波波动方程的传播特性， 研究P_SV转换波，分析其传播特征，用来指导其在储层预测中的应用.通过研究分析可以看出，P_SV转换波通过含油气介质时受影响比较少，能够得到比纵波好的多的成像资料.

| Abstract: | The anisotropy of rock is closely related to the migration and accumulation of oil and gas .Transverse wave is sensitive to anisotropy. Therefore it can offer invaluable information for oil exploration and development . Due to the anisotropy of rock, when the compressional wave propagates in the subsurface, it will create compressional wave and transverse wave on the interface of wave impedance. So we can use this information to research the physical property of the rock. This paper is based on the finite difference and aimed at the reservoir geological property. We utilize the wave equation propagation characteristics of elastic wave to research P-SV converted wave, and analyze its propagation characteristics to direct its application in reservoir prediction.The result shows that the transverse wave has a better image than the compressional wave when they travel through the reservoir. |
