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.

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。

To overcome the problem in synthetically analyzing various post-stack seismic attributes, a new integrated analysis method is developed. The chosen seismic attributes are integrated into one statistic analogic map by multiple attributes cross-plot analysis and statistic analogic technique.

To overcome the problem in synthetically analyzing various post-stack seismic attributes, a new integrated analysis method is developed. The chosen seismic attributes are integrated into one statistic analogic map by multiple attributes cross-plot analysis and statistic analogic technique. Four steps are followed to make statistic analogic map: (1) Attributes optimizing by analyzing multiple attributes cross-plot; (2) Choosing datum mark to calculate the base value of each attribute; (3) Sorting the chosen attributes by the magnitude of their basic value; (4) Integrating the sorted map to make statistic analogic map. The map shows the similarity between each location in the study area and the location chosen at oil&gas well or dry well, thus it can predict both favorable and poor sectors of oil & gas bearing. The predicted results have been confirmed by drilling.

利用常规叠后地震资料提取的地震属性很多,在进行属性综合分析时会遇到很多问题,为此,提出了一种叠后地震属性综合分析方法。其基本思想是:利用多属性交会图分析方法,根据研究目的对众多属性进行筛选; 利用统计类比方法把优选的属性信息综合到一张图中;利用统计类比的结果进行油气聚集有利区带和不利区带预测。生成统计类比图的过程分为4步:在确定了控制点(通常为井点)基准区的基础上,①利用多属性交会图分析技术对基准区内的属性进行优选;②选择基准点,计算基准点的属性基准值;③按基准值的大小对属性进行分类;④将分类后的平面图相加,得到统计类比图。统计类比图给出了整个研究区中每一基准点与控制点相似属性的个数,因为控制点一般选为油气井位或干井位,因此,可利用统计类比图进行有利区带和不利区带的预测。在某一地区利用地震属性组合分析方法进行了有利区带预测,预测结果与钻井结果较吻合。
