| 摘 要： | 地震均方根振幅与岩石密度呈正相关,因此可以利用地震均方根振幅大小来识别岩性,判别岩相。在十屋工作区选择了16口钻遇营城组的钻井,对与切片对应的15 ms内的营城组岩性、岩相进行统计,分析统计了岩性、岩相与对应几种均方根振幅属性。根据均方根振幅颜色数值的大小,把均方根振幅等时切片上各点分成强、强-中、中-弱和弱4个等级。在均方根振幅等时切片上按照等级来划分区域。以地震响应特征对应的地质意义为依据,对划分区域的岩性、岩相进行预测。将本区岩性划分为砂岩、泥岩,岩相划分为三角洲相、扇三角洲相和湖泊相,并据此制作了研究区营城组沉积微相平面分布图,进而确定了研究区发育的4个沉积体系:西部沉积体系、东部沉积体系、东北部沉积体系和南部沉积体系。通过钻井验证了南部沉积体系的存在。

| Abstract: | Seismic RMS amplitude is positively correlated with density of rock.The values of RMS amplitude can be used to identify lithology and lithofacies.The statistics of lithology and lithofacies of Members IV of Yingcheng Formation,which corresponds with the 15 ms time slice,is taken through the selected 16 drilling wells with Yingcheng Formation in Shiwu area.The lithology,lithofacies and RMS amplitude attributes which corresponding with them are analyzed.According to the size of the color's value of RMS amplit... |
