中文摘要: 鄂尔多斯盆地南部中生界油气运移的主要动力上部和下部分别以静水压力和差异压实所产生的流体压力为主,据动力学特征、油源发育状况、封闭条件等因素,可将成藏动力学系统划分为四类:(1)它源超压成藏动力学系统;(2)自源超压成藏动力学系统;(3)自源常压成藏动力学系统;(4)它源常压成藏动力学系统.并指出镇原-泾川地区应加强自源超压和自源常压成藏动力学系统的油气勘探,而宜君-旬邑地区则以它源超压、自源超压成藏动力学系统为主要勘探对象.
Abstract:The main dynamic force driving the migration of Mesozoic hydrocarbons in the southern Ordos basin was mainly hydrostatic pressure in the upper part and differential compaction in the lower part. According to the dynamic characteristics, development of the hydrocarbon source and sealing conditions, four accumulation-forming dynamic systems may be distinguished:(1) the allogenic superpressure accumulation-forming dynamic system, (2) the autogenic superpressure accumulation-forming dynamic system, (3) the autogenic normal pressure accumulation-forming dynamic system, and (4) the allogenic normal pressure accumulation-forming dynamic system. Efforts should be intensified to carry out hydrocarbon exploration in the autogenic superpressure accumulation-forming dynamic system and autogenic normal pressure accumulation-forming dynamic system in the Zhenyuan-Jingchuan area, while in the Yijuan-Xunyi area the main hydrocarbon exploration targets are the allogenic superpressure accumulation-forming dynamic system and autogenic superpressure accumulation-forming dynamic system.
