石臼坨凸起新近系岩性圈闭识别与刻画关键技术
|
摘要
规模性的区域岩性勘探要求高精度、高时效的岩性圈闭识别与刻画.对石臼坨凸起新近系明下段进行层序地层划分,建立层序地层格架,分析体系域内沉积砂体的发育规律,明确砂体的地质-地球物理响应关系.在此基础上,提出了适用于凸起区的岩性圈闭识别与刻画配套技术:基于地震属性提取的定性识别技术和基于地震多属反演的定量评价技术,实现了层序格架下岩性圈闭的快速、精细刻画.经钻井证实,该技术系列在凸起区滚动勘探中取得了很好的应用效果,钻探地质成功率达到100%,再发现一个新的亿吨级油田.
Scale lithological exploration requires high accuracy and timeliness of lithologic traps to identify and description.Based on the sequence stratigraphic theory,the sequence in the lower Neogene Minghuazhen formation in the Shijiutuo Uplift is classified,the strata framework of sequence is defined and stabled,the distribution laws of sedimentary sandbody is analyzed and geological-geophysical response relationship of sandbody is also revealed.Identification and description technology for lithologic traps realizes fast and precise sandbody characterization,including qualitative appraising technique of identifying lithologic traps by seismic attribute and quantitative appraising technique of lithologic traps by seismic multi-attributes inversion.Good application results achieved in the lithological exploration of shjiutuo Uplift,geological successful rate of 100%,and the discovery of a new one hundred million ton oilfield.
