吐哈盆地台北凹陷葡北东斜坡含油性检测

摘要
在地震属性-地质分析的基础上,利用信息分解技术、压制断层及泥岩等地震信息,结合已知油水井的产油气情况,可以大致确定油层的范围。在多属性优选的基础上,建立地震属性与储集层含油性的关系,并通过多种评价模型,利用信息融合、拓扑聚类、多参数分类等方法,达到各种特征场最佳综合的目标,从而减少了多解性,更精确地确定油层的平面分布范围。对邻近没有钻井的砂体,也可以类比判断出其最有可能含油的位置。
Based on the seismic attribute-geologic analysis,fault and shale seismic data analysis,integrated with output from available wells,the oil-bearing area can be generally determined.The relationship between seismic attribute and oil-bearing property can be established based on multi-attribute optimized parameters.By using several evaluating models,information synthesis,clustering and multi-parameter classification,the optimal target with various character fields can be reached,thus decreasing the multi-solution possibility,more precisely determining the range of oil layer distribution.For adjacent sand body without drilling data,the most possible oil-bearing intervals can be deduced by comparison.
