基于二维三分量资料的裂缝预测
|
摘要
基于裂缝介质横波分裂特征的三维三分量地震资料裂缝预测技术已取得较好的应用效果,而利用二维三分量地震资料预测裂缝还需进一步试验研究。在二维三分量资料裂缝响应特征分析和裂缝检测方法原理讨论的基础上,通过对二维三分量资料的水平分量进行旋转以及快、慢横波相关的处理,基于快、慢横波成像的相似性,建立了根据二维三分量资料裂缝响应的相似系数函数进行裂缝预测的方法。实际二维三分量资料预测出的裂缝方向与工区断裂系统方向相符合。
Fracture prediction by using 3D3C seismic data based on S-wave splitting characteristics of fracture media has achieved good application results;however,the utilization of 2D3C seismic data for fracture prediction need further research.Firstly,fracture response recorded on 2D3C seismic data is analyzed and the fracture detection principles are discussed.Then,rotation of horizontal components of 2D3C seismic data and correlation processing of fast and slow S-wave are carried out.In accordance with the imaging similarity of fast and slow S-wave,a similarity coefficient function for 2D3C seismic data is established to predict fracture.The predicted direction of fracture by using actual 2D3C seismic data is coinciding with the direction of faulted system in the area.
