鄂尔多斯盆地二叠系盒8段沉积特征再研究
Research on sedimentary environment of the Member 8 of Middle Permian Xiashihezi Formation in Ordos Basin,China
摘要
Abstract
The Member 8 of Middle Permian Xiashihezi Formation (He-8)in Ordos Basin is the main natural gas producing reservoir.Based on approximate 900 drilling wells data and some outcrop sections from the basin margin,combined the methods of paleocurrent direction analysis,heavy mineral statistical analysis, lithology analysis, and section structure analysis, the intrinsic characteristics of old lands,paleocurrents and deposits with respect to the strata of the Member 8 of Xiashihezi Formation were analyzed.The study results in new sedimentary features and sedimentary patterns in the area.It reveals that the sedimentary stage of the section 8 of Xiashihezi Formation is controlled by two oldlands in the north and the south respectively and the rivers originated in the north and the south are connected at that stage.The catchment area occurs in east of Duoning,Hejing and Hancheng of Shanxi Province,instead of in the Ordos Basin.关键词
