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.
