模糊数学综合评判法在圈闭地质评价中的应用探讨
杨昌明王美丽
( 中国地质大学#武汉)
提要: 圈闭地质评价是进行油气资源评价的基础性工作, 在评价某一圈闭是否含油气时,
其客观结果已经存在, 但对这一组圈闭的含油气性及其优劣的相对顺序的映象却是一个模糊
概念, 因而, 石油勘探人员很难依据这一模糊映象来准确回答圈闭是否含油气及其优劣的问
题。而模糊数学可以把/ 亦此亦彼0中介过度的模糊概念用数学方法来处理, 从而可以对圈闭
含油气性及其优劣程度进行定量分析评价。这即是应用模糊数学方法对圈闭含油气性进行评
价的理论依据。
APPROACH ON PREHENSIVE EVALUATION METH OD
OF BLURRED MATH EM AT ICS TO GEOLOGICAL EVALUAT ION OF TRAP
Yang Changmin Wang Meili
( Chinese Geological College#W uhan)
ABSTRACT: Geological evaluation of trap is basis of ev aluation on oil - gas resources
evaluation. When evaluating w hether a trap bearing oil- gas, its objective results has already
existed, but oil- gas bearing formation of the set of trap and relative order of advantage and
disadvantage is a blurred concept, so it is difficult for oil explore personnels to answer accurately
problems on oil- gas bearing formation and its advantag e and disadvantage. Blurred mathematics
can handle the blurred concept w ith mathematic method, and quantitatively analyses and evaluate
oil- gas bearing formation and degree of advantage and disadvantage of trap. This is theoretical
basis on applying blurred mathematics to evaluate oil- g as bearing formation of trap.
一、应用模糊数学法进行圈闭地质评价的理论依据
石油天然气勘探中的圈闭评价是指从盆地勘探阶段优选出有利含油气区带进行圈闭准备
开始, 到通过预探井钻探发现工业性油气流并进行储量计算的全过程。它以油气成藏理论为
依据, 以石油天然气
