利用地层切片多属性综合分析进行沉积相研究

Multiattribute Analysis of Stratal Slicing to Sedimentary facies

利用地层切片多地震属性综合分析,结合岩心、测井资料,研究了中亚南部X油田A组沉积微相的平面展布特征。通过该方法研究得出:物源主要来自油田南部和东南部,强水动力的辫状河三角洲前缘水下分支河道不断合并、分叉、迁移、向前推进;同时,反映此时地形坡度相对较缓,水动力整体较强,物源供给较充分。

Using multiattribute analysis of stratal slice,combining with core and logging data,we do some research into plane microfacies distribution of X oilfield in south of central Asia.From the results we can know: The primary provenance comes from the south and southeast of oilfield,underwater distributary channels of braided river delta controlled by powerful hydrodynamic environment merge、bifurcate、migrate and move forward.Meanwhile,we can know terrain slope is comparably gentle at that time,hydrodynamic force is strong in the whole and provenance supply is fairly sufficient.
