摘    要:研究区构造高部位三角洲前缘储层发育程度较差,对储层成因及岩性油气藏分布规律研究有待深入.针对储层成因与分布等问题,本文运用层序地层对比与砂体成因分析等手段,发现研究区在北西低、南东高、沟谷相间的古地貌背景下,东三段发育了三角洲前缘水下分流河道砂体.以砂体的成因信息为线索,依据砂体的地球物理响应特征,运用种子点追踪与沿层属性提取等手段预测了三角洲前缘水下分流河道砂体的分布.预测结果表明,古地貌控制了水下分流河道砂体的展布,水下分流河道砂体的上倾尖灭部位是开展岩性油气藏勘探的有利目标.

关 键 词:水下分流河道砂体  古地貌  地震相  地震属性  识别  预测

Abstract:It is quite necessary to do further research on the distribution of the delta front sandy reservoirs since the distribution of litho-traps and the genesis of the sandy reservoirs are still unclear in the study area.Through paleo-geomorphology study,sequence stratigraphy correlation and reservoirs' genesis analysis,the sub-channel sand bodies along the delta front are recognized.Based on the seismic response of the sand bodies,the distribution of sub-channel sand bodies has been predicted by the method of seed point tracking and the technology of attributes imaging along horizon.The results show that the distribution of sub-channel branch is mainly controlled by the paleo-geomorphology.The pinch out belts of the sub-channel sand bodies would be the favorable targets for the future litho-traps exploration in this area.
Keywords:sub-channel branch sand body  paleo-geomorphology  seismic facies  seismic attributes  recognition  prediction
