油气田在区域构造上的分布规律

本文通过对已知油气田和区域构造的对比分析,认为我国多数油气田在区域构造上具有明显地分布规律,并主要表现在四个方面,即：油气的富集与分布直接受深坳陷的控制,油气藏的分布与二级构造带关系密切,凹陷的陡带油气富集程度往往较高;断裂是控制油气富集与分布的重要因素。这是作者多年来研究高精度航磁成果与油气关系的一点粗浅认识,现归纳整理出来,以供油气勘探工作者今后勘查油气时参考。

THE DISTRIBUTION REGULARITY OF OIL AND GAS FIELDS ALONG REGIONAL TECTONICS

Based on a comparative analysis of oil and gas fields and regional tectonics, the author holds that most oil and gas fields of China exhibit obvious distribution regulariy along regional tectonics, and this mainly finds expression in four aspects: the enrichment and distribution of oil and gas are directly controlled by deep depressions; the distribution of oil and gas accumulations is closely related to saced-order tectonic belts; the degree of oil and gas enrichment is relatively high in steep belts of the depressions; fractures constitute an important factor controling the enrichment and distribution of oil and gas. The above superficial understanding acquired by the author through yan of research on relations between high-precision aeromagnetic rasults and oil and gas fields is summed up in this paper for geologists' reference in their exploration of oil and gas fields.
