【摘要】 火山岩油气藏是近年来热点勘探领域,三塘湖、准噶尔盆地已相继在火山岩储层取得了突破。吐哈盆地下含油气系统与相临盆地具有相似的石油地质条件,地震、钻井、重磁电资料显示,盆地火山岩发育广泛,成带分布。盆地下组合烃源岩厚度大、分布广、成熟度较高。盆地下组合在钻井中已见到了油迹显示,展示了良好的勘探潜力。吐鲁番坳陷南缘的迪坎尔构造带、鲁东构造带、塔克泉构造带和哈密坳陷的黄芦岗构造带、堡东构造带位于盆地南北两条强磁异常带内,预测这些区域火山岩储层发育,其下组合目的层埋藏浅,资料品质较好,占位较为有利,是近期火山岩油气藏有利勘探探索区域。更多还原

【Abstract】 Volcanic reservoir has been becoming the hotspot prospecting region in recent years.Breakthrough has been made in Santanghu and Zhunge’er basin.The lower hydrocarbon-beating system of Tuha basin possesses the same petroleum geological condition as the adjacent basins.The data of seism,drilling,gravity and magnetism survey,and electricity well logging,etc,show that lava distributes widely and zonally in Tuha basin.The source rock of the lower hydrocarbon-bearing compounding deposits thickly,distributes widely,and maturates highly.Oil stains has been found during drilling in the lower hydrocarbon-bearing compounding,which shows its favorable prospecting foreground. Between the basin’s south and north zones of extremely high magnetism,there lies such tectonic zones as Dikan’er, Ludong,Takequan tectonic zone of Turpan depression,and Huanglugang and Pudong tectonic zone of Hami depression. It is forecasted that these zones would be the favorable prospecting regions of volcanic reservoir in the future years by reason of their widely deposited lava reservoir,shallow embedding depth,good datum quality,and the good advantaged location.更多还原
