国内外前陆盆地油气藏特征分析与初步认识

前陆盆地是世界上不同的含油气盆地原型中油气最富集的一类,石油地质条件优越,具有较大的勘探潜力,本文对比分析了国内外前陆盆地及其周缘造山带之间的的盆山耦合关系及油气藏的控制因素与分布规律,在此基础上形成了对国内外前陆盆地油气藏特征的初步认识,认为国外典型前陆盆地结构较为单一,一般叠置于被动大陆边缘或弧后盆地之上,而中国中西部典型前陆盆地基底结构十分复杂,具有多演化阶段、多成因类型特点,油气的分布主要与褶皱冲断带的发育特征有.

Characteristic analysis and initial understanding of hydrocarbon distribution of foreland basins in the world

Foreland basin is the richest in oil and gas distribution of the world's different petroliferous basins. It has more favorable petroleum geology conditions and greater exploration potential. In this paper, the authors compare and analyze the coupling relationship between basins and adjacent mountains of foreland basins and the controlling factor of oil and gas, then acquire the initial understanding of the oil and gas reservoir characteristics foreland basins. That the structure of foreign typical foreland basin is a single, generally superimposed over a passive continental margin or back-arc basins. While the basement structure of Chinese central and western foreland basins is of much complexity, multi-stage evolution and more cause types .The distribution of oil and gas is related to the development characteristics of the fold-thrust belt.
