| 摘 要： | 裂隙介质的横波响应能提供对裂隙走向与密度一种直接测量.为了探测YC地区裂隙型储层特征，在该区进行了纵波源三分量数据采集.经过精细地处理，YC地区转换波成像质量得到了改善.以此为基础，对该区的裂隙特征进行了预测.预测结果与本区的应力场分析和钻井揭示的裂隙特征比较吻合.本文所介绍的一些关键转换波资料处理技术、解释方法和分析结论对今后陆地转换波勘探有一定借鉴作用.

| Abstract: | Shear wave responses to fracture media can serve as a tool to measure directly fracture strike and density.Three component data acquisition with compressional wave source was applied to YC area for predicting fracture reservoir characters. Imaging quality of the converted wave has been improved by precise data processing in YC area.On the base of this set of data,the predictive fracture characters are coincident well with the results from stress field simulating and drilling.The vital data processing techniques,interpretation methods and some inclusions in this article are of great benefit to further onshore inverted wave exploration. |

| Keywords: | converted wave fracture detecting common converted-point the ratio of the compressional wave velocity to shear wave velocity anisotropy |
