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。
The regional structural pattern of the Qintong sag in the Northern Jiangsu Basin consists of a half-graben fault syncline and its associated faulted uplift, with the main faults in the area being the NEE direction and the EW direction. Based on this, 14 secondary tectonic units were divided into 14 samples in the work area of Qintong Depression, and the geological conditions of qualitative description were evaluated by fuzzy mathematics method. The weighted average method was used to transform the value of data points For the zone score, R-factor analysis method is applied to the zone evaluation of oil and gas resources. In order to evaluate the overall sample with poor correlation between parameters, the main components of the factor analysis were evaluated by fuzzy comprehensive evaluation, and the concepts of blank value and calibration value were introduced to make the vertical superposition of the judgment results of multilayer system explore. The comprehensive evaluation results of 14 zones with single-layer and multi-layer systems are given, which make full use of the hydrocarbon geological data such as reservoir captive and captive protection in the detailed investigation stage to make a comprehensive assessment of the constituency for the next exploration. And designed the overall plan of exploration and development.
