【摘要】 华北地区的构造演化大致经历5个阶段,即陆核及基底形成阶段;中、新元古代裂陷槽发育阶段;古生代稳定地台发育阶段及其南北缘的造山作用;中生代中后期欧亚构造域与滨太平洋构造域过渡期;新生代滨太平洋构造域大发展时期。区域构造演化对渤海湾乃至华北地区油气的形成和分布具明显控制作用,主要表现在:中生代隆坳相间格局决定了古生代油气勘探的方向,是勘探新生古储潜山油气藏的主要地区;渤海湾盆地火山岩油气藏勘探也是今后一段时期内重要的勘探领域之一;渤海湾裂陷盆地构造演化的阶段性使得油气藏的分布在垂向上具有“三层楼式”的含油模式;构造迁移性导致渤海湾盆地油气藏在平面上的分布具有一定的规律性。更多还原

【Abstract】 The tectonic evolution of the North China region roughly experienced five stages, i. e. the continental nucleus and basement formation stage, the Mesoproterozoic and Neoproterozoic aulacogen development stage, the Palaeozoic stahle platform development stage with orogenic movement on its north and south margins, the middle and late Mesozoic transitional stage from the Eurasian tectonic domain to marginal-Pacific tectonic domain, and the Cenozoic marginal-Pacific tectonic domain development stage. Regional tectonic evolution had obvious controlling effects on the petroleum formation in the Bohai Bay basin and even the North China region. The framework of alternately arranged uplifts and depressions determines the targets of exploration for Palaeozoic petroleum and Meso-Cenozoic buried-hill petroleum accumulations. The NE-trend-ing deep faults control the development and distribution of Meso-Cenozoic volcanic rocks in the Bohai Bay basin; so the exploration of volcanic rock oil-gas pools is a very important in the future. As the tectonic evolution in the Bohai Bay basin progressed stage by stage, the distribution of oil-gas pools show: a three layer oil-bearing model in the vertical sense. Tectonic migration determines that the distribution of oil-gas pools have a certain regularity in plan in the Bohai Bay basin.更多还原
