摘要
文中以岩相古地理的观点论述了华北盆地的地质发展历史，即中晚元古代为古陆区，南北边缘地带发育拗拉槽型沉积；古生代为稳定的海相地台类型沉积；中新生代为陆相断－坳陷盆地沉积。指出华北盆地成烃、成藏的规律以及勘探油气的６个领域：一是以任丘古潜山为代表的“新生古储”油气藏；二是第三系“自生自储”复式油气聚集带；三是中、上元古界燕山拗拉槽原生油气藏领域；四是以孔古３井、７井油藏为代表的“古生古储”油气藏；五是以孔古４井油藏为代表的“古生中储”’或“古生新储”型油藏；六是中生界湖相沉积含煤地层烃源岩，虽改造剧烈，残留体肢离破碎，但仍是一个找油的新领域。
From the viewpoint of lithofacies and paleogeography this paper describes the geological developmental history of North China Basin,where in middle-late Proterozoic Era it was a paleo-land with sediments of aulacogens developed in its north and south margins. In Paleozoic Era stable marine sediments of platform type covered it. And in Meso-Cenozoic Era continental fault-depressional basin sediments well developed. According to its petroleum generation and accumulation regularities,six propect areas for oil and gas exploration are pointed out: (1)Oil and gas pools of 'Cenozoic source and pre-Mesozoic reservoir' type represented by Renqiu paleo-buried hill; (2)Tertiary complex petroleum accumulation belts of 'self-souce and self-reservoir' type; (3)Middle and Upper Proterozoic original oil and gas pools in Yanshan aulacogen; (4)Oil and gas pools of 'Paleozoic source and paleozoic reservoir' type represented by well Konggu-3 and Konggu-7; (5)Oil pools of 'Paleozoic source and Mesozoic/Cenozoic reservoir' type represented by well Konggu-4; (6)Mesozoic coalbearing formation of lacustrine facies,which is still a new prospect field for oil and gas exploration although it was seriously deformed during its evolution and is now in tatters.
