摘要：

作者用宏观评判与微观评判相结合的方法,对海安凹陷南部的圈闭进行评价。文中介绍了各评价因素的隶属度函数的求取及模糊评判矩阵的合成,结果将 36 个圈闭分为三类。

Abstract:

A method of macro-judgement and micro-judgement in which eight factors including tectonic position,oil-generating condition,reservoir condoition,cap-rock condition,mi-gration and accumulation condition,preservation condition,reliability and seismic stratig-raphy formd the factor set of macro-judgement,and the other six factors containing trap type,trap area,closing height,Percentage of sandstone and mudstone,effective space of reserve,burial depth of the target stratum formed the factor set of micro-judgement was adopted in this paper.It is also introduced concretely how to obtain subordinate functions of every factor and to compose fuzzy judgement matrixes.As the result of judging,36 traps in Haian Depression could be divided into three types.
