| 摘 要： | 汤原断陷构造岩性复杂,岩性分选是本区储层预测的关键。采用测井-地震多参数属性提取对密度曲线进行重构,消除井壁垮塌、裂缝等因素的影响。利用层序格架内多参数井约束反演方法,将层序格架研究与储层反演相结合,对汤原断陷新安村组SX1R单元进行岩性预测,预测成果与实际钻井资料吻合较好,符合程度达到87.63%。通过层序地层格架的井约束反演得出高分辨率反演数据体,刻划出目的层砂地比与砂岩的空间分布,揭示岩性展布规律:砂体厚度中心主要分布于控盆断裂一侧的深凹陷带,砂岩主要分布于西部斜坡、东部边缘和中央隆起带。

| Abstract: | The lithology is complex in Tangyuan faulted depression,so the lithological sorting is the key to reservoir prediction in this area.The density curve is reconstructed,which is based on logging-multiple seismic attribute extraction,to eliminate the wall collapse,crack and other factors.Multi-parameters well constrained inversion method based on the sequence stratigraphic framework is used to predict the lithology of SX1R unit of Xin’ancun formation in Tangyuan faulted depression,Predicted results agree well with the actual drilling data and the predict-rate reach 87.63%.The high-resolution inversion data volume is obtained through the sequence stratigraphic framework of the well constrained inversion,and it depicts rate of sand thickness than the target layer thickness and the spatial distribution of sandstone,also it reveals the rule of lithological distribution: sand thickness center is located in basin side of the deep depression fault,and the sandstone is mainly distributed in the western slope of the range,the eastern edge and the central uplift. |
