    RESEARCH ON RESERVOIR DISTRIBUTION OF BEACH BAR SANDSTONE IN LINNAN SUB-SAG BELT

    • 摘要: 临南洼陷带沙四段滨浅湖滩坝相成因的砂体广泛发育,近年来已成为该区十分重要的勘探后备阵地。但该区火成岩发育,地震资料品质较差,滩坝砂的分布发育不清,不利于勘探部署。在深化研究沙四上亚段古地貌、沉积特征的基础上,运用频谱分解等技术提高地震资料分辩率,综合利用了正演及属性分析等技术,对滩坝砂岩的发育范围进行了预测,取得了良好的效果,为该层系油藏的勘探提供了可靠的依据。

       

      Abstract: The sand bodies dominated by near shore shallow lake beach bar facies are well developed in the Es4 of the Linnan Sub-sag Belt. The region has become one of the important exploration targets in recent years. Because of the development of igneous rocks, and poor quality of seismic data, the distribution and development of beach bar sand are not clear. Therefore, based on the deepening research of the palaeogeomorphology and sedimentary features in the upper Es4, the resolution of seismic data is improved by using frequency spectrum decomposition technology. The forward modeling and attribute analysis technology is used comprehensively. The development pattern of beach bar sandstone is predicted in this paper and proven effective.
