摘要
灰色聚类法从系统内部模糊不清这一基本点出发，避开了人为给定各因素权重这一棘手难题，适用于解决信息量较少的问题，在合浦盆地勘探中，以油源条件（圈闭距低熟区距离，镜质体反射率），储层条件（砂岩厚度，有效孔隙度），保存条件（泥岩厚度，圈闭埋深），圈闭把握值（圈闭面积，构造幅度）等4项基本条件的8项指标作为评价因素，对40个圈闭进行了灰色聚类，其结果与实际勘探结果基本吻合。
Gray cluster theory,based on the vague internal structure,may avoid the difficulty of manually providing weights,and is effective when information is insufficient.During the exploration in Hepu Basin,with the four basic geologic conditions,including the hydrocarbon source rock condition(distance from inmature area and R o),reservoir condition(sandstone formation thickness and porosity),preservation condition(shale bed thickness and trap depth),and trapping condition(trap area and elevation),as evaluated elements,40 traps were clustered,and the results coined well with realities.
