结构-层序分析方法借助结构-层序模型和时频 分析技术,通过对地震剖面的定量分析,建立层序 体与时频特征、储层含油性与时频能量间的对应 关系,结合地质、测井、钻采等多种资料,对勘探 目的层进行层序分析、旋回划分、储集层预测及目 标定量描述。结构-层序分析的基础是建立有效 结构-层序模型和其地震响应特征,在此基础上, 将结构-层序分析技术应用于陆相断陷盆地的陡 坡带砂砾岩体、缓坡带三角洲、低位扇体以及其它 隐蔽油气藏的勘探,取得了较好的勘探效益。
Structure-sequence analysis method By means of structure-sequence model and time-frequency analysis, through the quantitative analysis of seismic profiles, the relationship between sequence body and time-frequency features, reservoir oil content and time-frequency energy is established. , Logging, drilling and other information, the exploration target layer sequence analysis, cycle, reservoir prediction and target quantitative description. The basis of structure-sequence analysis is the establishment of an effective structure-sequence model and its seismic response characteristics. Based on this, the structure-sequence analysis technique is applied to the steep slope glutenite body in the continental rift basin, , Low fan and other subtle reservoirs exploration, and achieved good exploration benefits.
