【摘要】:利用野外露頭、測井曲線、巖心等資料,結(jié)合層序地層學(xué)方法,在四川盆地涪陵地區(qū)五峰組-龍馬溪組一段沉積構(gòu)造認(rèn)識(shí)的基礎(chǔ)上,針對(duì)涪陵地區(qū)五峰組-龍馬溪組一段層序格架與沉積演化開展了整體性的研究。研究表明:涪陵地區(qū)五峰組-龍馬溪組一段可以劃分出2個(gè)三級(jí)層序,五峰組-觀音橋組為一個(gè)三級(jí)層序SQ1,由海侵體系域(TST)和高位體系域(HST)組成;龍馬溪組一段可以劃分為一個(gè)三級(jí)層序,由海侵體系域(TST)、早期高位體系域(EHST)、晚期高位體系域(LHST)組成;進(jìn)一步,分析其層序構(gòu)成特征并通過對(duì)層序地層格架的建立,提出了涪陵地區(qū)五峰組-龍馬溪組一段層序受海平面、生物、火山等多因素控制的沉積演化模式,為開展頁巖巖相等研究奠定了基礎(chǔ)。
[Abstract]:Based on the field outcrop, logging curve, core data and sequence stratigraphy, based on the first member of Wufeng-Longmaxi formation in Fuling area, Sichuan Basin, the sedimentary structure of Wufeng formation-Longmaxi formation is recognized. An integrated study on the sequence framework and sedimentary evolution of the Wufeng-Longmaxi formation in Fuling area is carried out. The results show that the first member of Wufeng formation-Longmaxi formation in Fuling area can be divided into two third-order sequences, the Wufeng formation-Guanyinqiao formation is a third-order sequence SQ1, composed of transgression system tract (TST) and high system tract (HST). The first member of Longmaxi formation can be divided into a third-order sequence, which is composed of high-level system tract (LHST) in the early stage of transgression system tract (TST),) and high-level system tract (EHST),) in late stage. Based on the analysis of the sequence composition characteristics and the establishment of the sequence stratigraphic framework, the sedimentary evolution model of the first member of the Wufeng formation-Longmaxi formation in Fuling area, controlled by sea level, biology, volcano and other factors, is put forward. It lays a foundation for the study of shale equivalence.
