摘要/Abstract

摘要： 利用地质异常研究中的证据权重法，选择构造活动、烃源岩有机质丰度、烃源岩厚度、储层级别、储层复杂程度、盖层发育程度、地层水矿化度作为证据层，对中下扬子北缘下古生界油气成藏有利区带进行了评价。综合本地区石油地质研究成果，认为四川盆地北部、鄂西渝东地区、下扬子部分地区是本区最有利的勘探区。

关键词: 中下扬子北缘, 油气地质异常, 证据权重法

Abstract: Using evidence weight method, the authors selected tectonic activities, hydrocarbon abundance and thickness of source rocks, level of reservoir, complexity of reservoir, degree of mineralization of formation water as the evidence layers to evaluate the favorable zones of lower Palaeozoic pools at the north edge of the middle and lower Yangtze area. Finally, integrated with the study of petroleum geology of the area, the north of the Sichuan Basin, west area of Hubei and east area of Chongqing, and parts of the lower Yangtze area are considered as the most profitable areas of oil exploration at the north edge of lower and middle Yangtze area.

Key words: north edge of the middle and lower Yangtze area, oil geological anomaly, evidence weight method
