摘要
俄罗斯区域构造演化复杂,含油气盆地类型众多,油气地质特征和资源规模彼此差异巨大,盆地间缺少横向对比研究。基于最新的IHS数据库,通过对构造演化、沉积充填和基本石油地质条件的分析,总结了14个主要含油气盆地的盆地类型划分、油气地质条件类比、成藏主控因素和油气成藏模式,指明了未来需要重点关注的盆地。综合分析表明:俄罗斯含油气盆地具有以发育叠合盆地为主、单旋回盆地伴生的特点;存在4期主力烃源岩、4套主要成藏组合和3种成藏模式,储量发现规模受控于成藏模式,其中单旋回盆地封闭型成藏的油气资源最为丰富,其次分别为叠合盆地中的调整型成藏和改造型成藏。
The geology of Russia is hard to delineate because of its complex tectonic evolution, different ba- sin types, and variable petroleum geology and resources. Based on the IHS database, this paper analyses the tectonic ＆ sedimentary evolution, petroleum geology comparison, hydrocarbon accumulation controlling factor and accumulation model of 14 petroleum basins and then presents the rank of the potential of pe troleum basins. The results indicate that Russia develops more superimposed basins than monocycle basins and there are 4 cycles of source rocks, 4 assemblages of reservoir ＆ seal and 3 accumulation models. The resources vary with different basins. The most important basin is monoeycle basin with closed petroleum system like west Siberia Basin. Next is adjusting petroleum system of superimposed , such as Timan-Pechora Basin and Volga-Urals Basin. The third is the reworked petroleum system of superimposed basin like North Sakhalin Basin.
