济源—黄口地区油气勘探前景分析

从区域地质背景到具体油气地质情况，对济黄凹陷带的古地理演变及沉积构造、构造特征和发展历史进行了分析，同时介绍了三个凹陷不同烃源岩系油气资源量的计算结果，根据这些分析和判断，对济源、黄口等四个凹陷的油气前景作了比较评价。文章最后根据石油地质条件综合分析，提出了关于中、新生代和古生界油气勘探的一些轮廓性看法，认为中、新生界可能具有形成小型油气藏的地质条件。在勘探指导思想上应转到以古生界、特别是上古生界为主的深部气藏方面上来。

The Prospect Analyses of Oil & Gas Exploration in Jiyuan-Huangkou Area

This paper analyses the palaeographical evolution,sedimentary structure,structural feature and developing history of Jiyuan-Huangkou Depression from regional geo-logical background to concrete situation on oil & gas,and introduces calculated result aboutoil & gas reserves of different hydrocarbon source rocks in three depressions. According tothese analyses and Judgments, the prospects of reserves for four depressions in Jiyuan-Huangkou Area are compared and evaluated- At last,some outline views related to oil & gasexploration on Mesozoic era,Genozoic era and Palaeozoic erathem are presented on the basisof comprehensive analyses about petroleum gelogic conditions. The authors think that thereare geologic conditions of forming small oil & gas reservoir on Mesozoic erathem and Geno-zoic erathem. Therefore,the main expIoration should be concentrated upon Palaeozoic erath-em specially upon the upper Palaeozoic erathem.
