摘要
基于岩心和测井综合分析,充分利用反射强度斜率对层序的敏感性,研究塔河地区下石炭统巴楚组底部砂泥岩段的沉积相。根据地震属性反射强度斜率横向变化图,通过沉积旋回对比,识别出涨潮三角洲、沿岸滨面砂、消舄湖、障壁岛等沉积环境,较以往利用地震属性划分沉积相的其他方法更贴近实际。
Base on core and well log comprehensive analysis and the sensitivity of the slope of reflection strength of seismic attributes to depositional sequence, the sedimentary facies in sand-shale member of Bachu formation of Lower Carboniferous in Tahe oilfield of Tarim basin is studied, identifying flood tidal delta, coastal shoreface sand, lagoon and barrier island etc. from lateral variation map of reflection strength slope and sedimentary cycle correlation. The identified results are closer to real situations than those from utilizing the seismic attributes.
