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。

Abstract: 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 estabi shed 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.

Key words: Tuha basin, seismic attribute, information, analysis, oil-bearing property, detection
