摘要

苏北盆地溱潼凹陷区域构造格局

由箕状断陷与其伴生的断隆组成

区内断裂带主要为NEE向和EW向。以此为依据在溱潼凹陷工区范围内划分出14个二级构造单元作为14个样品点

对定性描述的地质条件运用模糊数学方法进行取值

并用加权平均的方法把数据点的值转化为区带的得分值

将R型因子分析方法运用于油气资源的区带评价。为了对参数之间相关性不好的样本总体进行评判

对因子分析得出的主成分进行模糊综合评判

并且引入空白值和标定值的概念

对多层系评判结果的垂向叠加作了探索。给出了14个区带单层系和多层系综合评判结果

最大程度地利用了详查阶段拥有的生储盖运圈保等油气地质资料

为下一步勘探做好选区综合评价工作

并设计出勘探开发总体方案。

Abstract

Regional tectonic framework of Qingtong Depression consists of fault-depression and fault-uplift. The faultzones trend mainly NEE and EW. Fourteen secondary structural units are divided as sample points in the depression.Fuzzy mathematical method is used to get the values of qualitative geological conditions of the depression

then the sample point data could be converted into zonal score Values by weigthed mean method

and finally use R-factor analysismethod to assess regional oil-gas reservoirs. In order to estiment those samples with poor parameter relativity

fuzzy comprehensive assessment is made for the main components derived from the factor analysis. The concept of blank-valueand calibrated-value was introduced to stack vertically multi-sequence assessment results.
