摘要 

鄂尔多斯盆地北部杭锦旗地区二维地震剖面揭示该区古生界之下存在一套断陷—坳陷构造层序。在前人研究的基础上,结合杭锦旗地区和盆地内其他钻井资料和二维地震资料,并对比野外露头测量和分析化验资料,对该断陷—坳陷层序的地层格架、时代、沉积特征和油气地质特征等进行了详细研究,提出了杭锦旗地区油气勘探思路。研究区元古宇地层受近南北向塔木汗正断层和道劳正断层控制,分别在研究区西部和中部形成两个半地堑断陷。断陷层与下伏太古宇呈角度不整合接触,坳陷层与上覆古生界呈角度不整合接触。 根据断陷层未变质陆源碎屑岩和构造层序特点推测其时代为中元古代长城纪。断陷层为粗砂岩、细砾岩局部夹浅海泥岩,扇三角洲—滨浅海陆源碎屑沉积,分布局限;坳陷层为杂色砂岩、细砾岩夹褐色泥岩,扇三角洲—混合陆棚沉积,分布广泛,将两个断陷区连成一片。断陷层中发现的天然气可能来自于上古生界煤成气。

Abstract

Based on the 2D seismic interpretation in the Hanggin Banner area of northern Ordos Basin,the authors found a rift sequence under Paleozoic strata.On the basis of previous studies and combined analysis of well,seismic data,outcrop and geochemical data in Hanggin Banner area,the stratigraphic framework,possible geological epochs,sedimentary features and petroleum geological conditions of the rift were analyzed.This paper provides new ideas for the exploration of oil and gas in Hanggin Banner area.The Proterozoic strata in the study area is controlled by the SN-trending normal faults of Tamuhan and Dalao,where two half graben fault depressions were formed in western and central part of the study area respectively.The fault depression layers overlie Archean strata and underlie Paleozoic strata in angular unconformities.According to the unmetamorphic terrigenous clastic rocks and tectonic sequence features,it is inferred that fault depression layers should be the middle Proterozonic Changcheng Formation.Drilling and seismic data reveal that the fault depression layer contains fan-delta coarse sandstone and fine conglomerate intercalated locally with neritic mudstones.Depression layer is widely distributed and contains fan-delta sandstone,fine conglomerate and tidal flat brown mudstone.The sandstone within fault depression layers contains coal genetic gas originating from Upper Paleozoic strata.
