补充资料:含油气盆地
含油气盆地 oil and gas-bearing basin 聚集有工业油气藏的沉积盆地。沉积盆地是指漫长的地质时期,地壳表面曾经不断沉降、接受沉积的洼陷区域。含油气盆地必须具备3个基本条件:①是一个沉积盆地。②在漫长的地质时期中,曾经不断沉降接受沉积,具备油气生成、运移和聚集的有利地质条件。③有工业性油气藏。因此,可将含油气盆地看作油气生成、运移和聚集的基本地质单位。在油气勘探中,常把含油气盆地作为一个整体看待,从其沉积发育史、构造发育史和水文地质条件出发,研究油气生成、运移和聚集地质条件,划分出油气聚集的有利区域。中国的柴达木盆地、准噶尔盆地、四川盆地都是含油气盆地。 含油气盆地由基底、周边和沉积物3部分组成。被未变质的沉积岩层所覆盖的结晶岩石称基底。基底时代决定着盆地形成和盖层沉积的时期,基底性质决定着盆地形态和盖层构造。基底时代和性质对盆地的发生和发展都具有十分重要的影响。周边即盆地的边界,其形状受基底性质和所在大地构造单位控制,周边与边界地质体的接触关系有超覆接触、断层接触以及二者相结合的断超接触3种。盆地内部沉积物的时代、性质和构造也受着基底性质和所在大地构造单位的控制。 含油气盆地分类较多,主要有3种分类方式:按槽台学说划分盆地类型;根据板块活动的性质分类;以古生代槽台体制和中、新生代板块构造体制为基础进行分类。 |
