4.The palaeogeographic research indicate that the palaeogeographic outline of the study area recorded the evolution from a sedimentary basin in which the shallow-water carbonate platform sediments and deep-water terrigenous clastic submarine fan developed from southeast to northwest and northeast during the Late Triassic through a submarine sheet-like model composed of deep-water sandy turbidite and fine-grained turbidite during the Early Jurassic to a terrigenous clastic barrier coast during the Middle and Late Jurassic and finally to the coal-bearing delta sediments during the Late Cretaceous.
古地理分析表明，研究区晚三叠世古地理轮廓是一个从东南向西北和东北方向由浅水碳酸盐台地及深水陆层海底扇沉积共同发育的沉积盆地；早中侏罗世，演变成为一个由深水砂质浊积岩和细屑浊积岩组成的水下席状体沉积；进入中晚侏罗世，其古地理表现为一个陆屑浅海有障壁海岸；到了晚
白垩世，研究区表现为以含
煤沉积为特征的三角洲相沉积。
7.Based on comprehensive analysis of the outcrops and interpretation of seismic data in this area,six detachments are identified,which are the Middle Permian Lucaogou and Hongyanchi Formations,the Lower Jurassic Badaowan Formation,the Middle Jurassic Xishanyao Formation,the Cretaceous Tugulu Group,the Palaeocene Anjihaihe Formation and the Neocene Taxihe Formation from the deep to the shallow.
通过大量地表露头的观察和地震资料的解释,系统识别和厘定了中二叠统芦草沟组和红雁池组、下侏罗统八道湾组、中侏罗统西山窑组、
白垩系吐谷鲁群、古近系安集海河组和新近系塔西河组等共6个与大套泥岩、膏泥岩和
煤系地层相关的主要构造滑脱层。
8.The study of buried history,geothermal history,source-reservoir-seal assemblage and hydrocarbon-expulsion history of the depression showed that the pools generated by the coal-related source rocks in the Upper Paleozoic were formed in two stages of the Late Mesozoic and the Palaeogene periods to present.
对黄骅坳陷孔西潜山埋藏史、地热史、生储盖发育史和排烃史的研究表明,上古生界
煤系烃源岩主要形成两期油气藏,第一期油气成藏发生在晚侏罗世—早
白垩世,该期生烃量有限,成藏规模较小;
