【摘要】 八面河地区沙四段滩坝砂体发育,呈现储层横向变化快,分布规律复杂等特征,对砂体的展布难以准确描述。通过对八面河地区沙四段滩坝砂的研究,建立了古地貌结合沉积特点分析储层分布区、地震属性分析描述滩坝砂体、成藏分析确定目标的滩坝砂体描述技术与方法,在面138等多个区块应用,效果明显。更多还原

【Abstract】 Beach bar sand bodies’ development in the fourth member of Shahejie Formation in Bamianhe presents the characteristics of an ever-changing condition in reservoirs horizontally and complicated layout pattern which caused difficulties in describing the spread of sand bodies accurately.Based on the study of beach bar sand in the targeted area,a set of description techniques and methods was established,consisting of analyzing reservoir distribution in reference to ancient landscape and sedimentation features,depicting beach bar sand bodies in terms of seismic attributes and locating target by formation assessment,and was proved to be effective after being applied to 138 and other blocks.更多还原
