| 摘 要： | 基于油气储层异常体及其边界处的突变特征提出了油气储层边界尖点突变技术.这种技术是将地震时间序列x(t)化为突变论中的尖点突变模型的标准形式v(x),进而可得出平衡曲面方程和分叉集方程,在此基础上,可求得突变参数,用以有效而准确地确定油气储层异常体的空间分布范围及其边界.

| Abstract: | Based on the catastrophe character of the oil/gas reservoir abnormal body and discontinuity features,this paper advances the oil/gas reservoir boundary cusp catastrophe technique.In this technique,seismic time series x(t)is transformed into the standard format v(x)of the cusp catastrophe model,and balance equation and forfication set equation can be obtained,then,catastrophe parameters can be estimated,which can determine the spacial distribution extent and boundary of an oil/gas reservoir abnormal body.Thi... |
