摘要：

圈闭评价的灰色关联分析就是研究实际圈闭与理想圈闭的近似程度,通过对比分析,赋于成藏因素以不同的权值,从而定量评价圈闭的成藏条件.江汉盆地西南缘圈闭的综合评价结果表明:谢凤桥构造为最有利构造;南岗1号、2号、3号断鼻,采穴断鼻及丁家湖断块为较有利圈闭,尤其是采穴和丁家湖构造,应是今后的主要勘探对象.

Abstract:

Grey associative analysis in trap assessment is to study the simularity between actural traps and ideal traps; give pool-forming factors different weights through correlation analysis so as to quantitatively evaluate trap's pool-forming condition. The assessment results of the traps on southwest margin of Jianghan Basin indicate that, Xiefengqiao structure is most favourable for hydrocarbon exploration; Nangang 1～3 and Caixue fault-noses and Dingjiahu fault-block are secondary. Caixue and Dingjiahu structures should be major exploration targets in future.

Key words: grey association, estimation, Jianghan Basin
