摘要
随着油田勘探开发的深入,低幅度构造的勘探逐渐受到重视。论述了低幅度构造油藏的2种成因及对其识别能力。结合研究区实际情况,提出了低幅度构造油藏的多种识别方法:优势频带相干数据体处理技术(识别小断层)、水平切片技术、自动追踪技术、溢出点约束技术、变速成图技术等,总结出了低幅度构造研究流程图。通过以上技术在冀东南堡凹陷高柳构造带新近系油藏发现了10个低幅度构造,目前已钻探了3个,均获得了工业油流,取得了较好的效果。
With further exploration and development of oil fields, the reservoirs with low amplitude structure are paid more attention to. Two origins and multi-identifications for such reservoirs are discussed and presented, integrated with studied area conditions. The identification methods include the coherent data volume processing technique with predominant frequency band to distinguish from small faults, the plane slice technique, auto-tracing technique, the spilling point restriction technique, the variable velocity mapping technique and the flow chart for studying the low amplitude structures. Application of these techniques to Neogene reservoir in Gaoliu structural zone of Nanpu sag, Ten low amplitude structures have been found, three of which been drilled, obtaining commercial oil flows. Also, two low-amplitude-structure reservoirs at C5 unit （Es2） in Chunhua field of Dongying sag have been found, and five wells been drilled with good responses.
