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。
The tectonic evolution in North China has roughly experienced five stages: the nucleus and the basement formation stage; the Neoproterozoic rift trough development stage; the Paleozoic stable platform development stage and the orogeny of the northern and southern margins; the mid-late Meso-Eocene Eurasian tectonics Domain and the Pacific Ocean tectonic transition period; Cenozoic pacific Pacific tectonic domain during the great development. The regional tectonic evolution evidently controlled the formation and distribution of oil and gas in Bohai Bay and even in North China, which mainly manifested in that: the pattern of Mesozoic uplift and inter-continental depression determines the direction of Paleozoic hydrocarbon exploration and is the main area for exploration of newborn buried hill oil and gas reservoirs; the Bohai Bay Basin The exploration of volcanic reservoirs is also one of the most important exploration areas in the future; the tectonic evolution of the Bohai Bay rift basin makes the distribution of oil and gas reservoirs vertical in a “three-storey” oil-bearing model; and the tectonic migration has resulted in the Bohai Sea The distribution of oil and gas reservoirs in the Bay Basin has a certain regularity.
