摘要
在精细勘探的要求下,依赖新的方法研究短时间尺度内砂体分布规律是现今的研究热点。以准噶尔盆地东部阜东斜坡区中侏罗统头屯河组为研究对象,通过露头、岩心、地震以及测井资料建立高分辨层序地层格架,将相关年代的时间地层分割成具有同步沉积演化序列的等时岩石组合体;利用优选的多种地震属性进行降维处理并融合,将相关时代岩石组合所反映的地震特征进行展现,两者结合恰好将相关时间域内砂体分布进行预测。研究发现,头屯河组SSC1—SSC10内多个砂体由北东-南西向叠置前积,其中厚度较大且连续性较好的砂体为主要勘探目标,预测砂体厚度同钻井钻遇砂体厚度基本一致,研究结果可为相似区域精细砂体预测提供新的思路。
Under demands of precise exploration,method for analyzing distributions of sand in short time domain is a hot point in recent years.Toutunhe formation in Fudong slope area,east of Junggar basin was taken as a study example.The high-resolution sequence stratigraphic framework was built based on outcrops,cores,seismic and logging data.Isochronic rock combination with synchronous sedimentary revolution sequence was divided by chronostratigraphic units of relative times.Multi-attributes were selected to reveal seismic characters of rock combination in relative time through dimension reduction and fusion.The distribution of sand body could be predicted in short time domain through integration of the above methods.The results show that sand body in SSC1-SSC10 of Toutunhe formation has foreset from Northeast to Southwest.The sand body are the main exploration targets for its thickness and good succession.Thickness of sandstone predicted was match well with the drilling wells,this brought a new method for precise sand body prediction in similar regions.
