【摘要】 冀中坳陷是渤海湾盆地古近纪以来形成的新生代陆内断陷盆地,盆地内具有丰富的油气资源,其中任丘潜山油气藏世界闻名,位于饶阳凹陷的马西地区古近系具有较大的油气勘探潜力。构造活动强烈盆地的构造控制沉积研究是近年来国际上沉积盆地分析和层序地层学研究的一个热点。从层序地层格架和古构造格架入手,深入分析同沉积断裂活动形成的古地貌对沉积物和沉积体系发育分布的控制作用,预测储集砂体的空间分布,对马西地区的油气勘探具有重要的理论和生产意义。论文以层序地层理论为指导,建立了马西地区古近系层序地层格架,把马西地区古近系地层划分为3个二级层序、10个三级层序。在层序地层研究过程中,充分考虑构造运动对层序和沉积的控制作用。通过地震资料构造研究,系统分析了区内的断裂特征和构造样式,对古近纪构造演化进行了划分,将古近纪的演化分为五期,分别是:断陷分割充填期、断陷扩张深陷期、断陷萎缩期、断坳扩展期和断坳抬升消亡期。沉积相研究过程中,利用地理物理手段进行了古地貌的恢复,分析古地貌对沉积体系的控制作用,研究认为:沙三段以湖泊为主,总体为浅湖-半深湖背景,在沉积过程中,来自东部的物源在马西洼槽内形成巨厚的沉积,此背景下的三角洲前缘砂体发育,是岩性油气藏勘探的有利层系;在东营组沉积期,工区的南部局部有小范围的湖相沉积,形成三角洲沉积体,是岩性油气藏勘探的有利地区。通过成藏条件分析认为,马西地区古地貌控制着多种类型的岩性地层圈闭,具有优越的成藏条件。主要分布在不同构造单元转换部位,是物源向湖盆的入水口,控制着有利储集相带展布,预测马西断层下降盘形成的三角洲沉积体和南部薛庄-八里庄地区东营组是岩性油气藏勘探的有利相带。更多还原

【Abstract】 The Jizhong Depression is a Cenozoic intra-continenta rift basin and formed since Cenozoic in Bohai Bay Fault Basin ,the basin is rich in hydrocarbon, including the world-class Renqiu buried hill reservoir, and has a great potential of hydrocarbon resources in Maxi area of Raoyang sag. In recent years, the research in tectonic controls on sedimentary of intense tectonic activity basin is one of the focuses in sedimentary basin analysis and sequence stratigraphy study. Based on the framework of sequence stratigraphy and paleo-tectonic, the article analyse the control efforts of synsedimentary activity fault ,which caused the ancient topography, on the system of sediment dispersion and development, forecast the spatial distribution of reservoir sandbody. The exploration and production of hydrocarbon in Masi area has important theoretical and production significance.The article base on the theory of Exxon sequence stratigraphy, set up the Paleogene sequence stratigraph of Masi area, devide into there II stratigraphic orders ,ten III stratigraphic orders.In the study of sequence stratigraphy, the article give full consideration to the tectonic control on sequence stratigraphy and sedimentary. Based on the research of the seismic data structure, the article analyse fault charccteristics and tectonic styles , divide the Paleogene tectonic evolution into five types, that is inheriting type, early prevailing type, transitional type, migratory type and subsiding type.Through the study of sedimentary facies, the ues of geophysical restoration of the ancient landscape, the article analyse the control efforts of ancient topography on sedimentary system, and suggest that : The deposition environment of Sha 3 formation is shallow-semi-deep lake, in the deposition process, the source material from the east along the fault of Masi is formed a thick depositon, delta front sandbody is relatively developed, is the favorable strata series in exploration of hydrocarbon. In the period of Dongying formation, there are small-scale lake-deposition in the southern of work area, it is formed fan-delta deposition and favorable lithologic hydrocarbon reservoir exploration areas. Analyzed the condition of reservioir , the ancient landscape of Masi area control many different types lithostratigraphic traps, and have the fine potential to form reservoirs. There are distributed in the different tectonic transition units, which are the source material of the inlet to the lake, controlled the distribution of favorable reservoir facies, forecasted that fan-delta deposition formation of Masi fault sole and Dongying formation of southern of Xuezhuang-Balizhuang is the favorable areas for lithologic hydrocarbon reservoir exploration.更多还原
