【摘要】 利用高精度三维地震资料,通过对时间域、频率域的地震属性分析,结合测井、钻井等资料分析了河道砂体的变化及分布规律,总结出一套在薄互层条件下利用频率域地震属性识别古河道的方法,并在大庆长垣以西他拉哈、常家围子地区的实际应用中取得了明显的效果.更多还原

【Abstract】 Based on the three-dimensional high resolution seismic data, the change of sandbody and its distribution are studied with the analysis of the seismic attribute in time and frequency domains, combined with logging and drilling data in the paper. A method to identify river palaeochannel deposition in the thin interbeded reservoir is presented from the seismic properties in the frequency domains and application of the method for the areas of Talaha and Changjiaweizi proved to be effective.更多还原
