由前人对含油气系统的定义总结引申到其重要组成部分,即含油气盆地。含油气盆地类型中前陆盆地在中国中西部油气开发中占有重要地位。就中西部前陆盆地发育的机制、构造位置、油气成藏特征及油气分布进行了简要的总结。前陆盆地划分出前陆褶皱冲断带、前渊坳陷带、斜坡带和前渊隆起带四个构造单元,各个构造单元的地质特征对油气形成和聚集都有不同程度的影响。 The predecessors’ summary of the definition of petroleum system extended to its important component, namely, the petroliferous basin. Petroliferous basins in the foreland basin in central and western China oil and gas development occupies an important position. The mechanism, structure location, hydrocarbon accumulation characteristics and oil and gas distribution of the foreland basin in central and western China are briefly summarized. The foreland basin divides four tectonic units of foreland fold-thrust belt, foredeep depression zone, slope zone and foreland uplift zone. The geological characteristics of each tectonic unit have different degrees of influence on the formation and accumulation of oil and gas.
