在介绍阜四段（E1f4）岩电性特征及识别标志基础上,叙述了戴南组与阜四段（E2d/E1f4）间可疑地层＂泥尾巴段＂剖面的属性,认为它是断陷期剥蚀下伏阜宁组（E1f）等地层形成的E2d泥屑流沉积产物。据此,对SHS1井E2d、E1f可疑地层精细划分,发现了一套E1f4高位域新地层,进而指出吴堡事件形成了E2d/E1f4区域不整合和箕状断陷格局的认识。
在介紹阜四段（E1f4）巖電性特徵及識彆標誌基礎上,敘述瞭戴南組與阜四段（E2d/E1f4）間可疑地層＂泥尾巴段＂剖麵的屬性,認為它是斷陷期剝蝕下伏阜寧組（E1f）等地層形成的E2d泥屑流沉積產物。據此,對SHS1井E2d、E1f可疑地層精細劃分,髮現瞭一套E1f4高位域新地層,進而指齣吳堡事件形成瞭E2d/E1f4區域不整閤和箕狀斷陷格跼的認識。

Aiming at several disputed geological issues related to Subei epigenetic-fault being,suspicious strata between E1f4 and E2d,which is so called ＇mud tail section＇,is clarified according to the analysis of lithologic and logging character.The identification mark of E1f4 ＇mud tail＇ stratum consists of mud debris flows deposits which came from strata of E1f eroded.According to above all,suspicious strata between E1f4 and E2d of well-SHS1 are precisely classified,and a highstand systems of E1f4 is put forward which indicates that regional unconformity between E1f4 and E2d and half graben rift basin were formed during Wubao Tectonic Events.
