摘要
古地貌恢复研究是油气储层预测的重要内容,古地貌恢复的准确性直接影响物源、古水流等沉积特征的判断。针对辽河滩海西部地区钻井分布不均的特点,在钻井资料地层厚度压实校正基础之上,提出利用地震资料进行井间古地貌趋势补偿,将钻井资料和地震资料有机地融合。通过在辽河滩海西部沙一段应用表明,该方法效果良好,能够较真实地反映古地貌分布特征。
The study of paleotopography reconstruction is an important part of reservoir prediction and the accuracy of paleotopography reconstruction directly impact sedimentary characteristics judgments,ancient water and others.In this paper,based on the characteristics of uneven distribution drilling in the western beach area of Liaohe basin and the stratigraphic thickness compaction correction of wells data,we propose using seismic data compensate paleotopography trends between wells,integrate well data with seismic data organically.The application of the approaches to Sha 1 member of the western beach area of Liaohe Basin shows that this method is effective and can factually reflect the characteristics of paleotopography.
