摘要(Abstract):
通过分析地震属性特征与地质特征的相关性对地震参数进行优选 ,在此基础上 ,利用神经网络方法对地震属性数据做变换 ,使变换得到的识别指数能更好地指示储层岩性信息 ,该技术在大庆外围油田太 1 9区块储层描述中应用 ,效果明显。
This paper optimizes seismic parameters through analyzing the relativity of seismic attitude characteristic and geologic characteristic Then it changes the seismic attitude data with neural network method so that the identification indexes can fully indicate reservoir lithologic information This technique is used in the reservoir description of Block Tai 19 of the peripheral Daqing Oil Field
