【摘要】：TN凹陷經(jīng)歷了侏羅紀(jì)至早白堊世裂谷盆地發(fā)育全過(guò)程,不整合面普遍發(fā)育。通過(guò)井震結(jié)合識(shí)別出不同級(jí)別不整合界面12個(gè),以超覆不整合、截超不整合、平行不整合及褶皺不整合4種類型為主。研究不整合結(jié)構(gòu),明確了不整合界面的封閉或疏導(dǎo)作用,當(dāng)不整合與構(gòu)造、斷層較好匹配時(shí)可形成有利圈閉。與不整合相關(guān)的油藏類型主要發(fā)育4種,分別為多層系疊加反向屋脊斷塊油藏、水下扇體的構(gòu)造-巖性油藏、砂體尖滅油藏和潛山油藏。結(jié)合油田生產(chǎn)實(shí)際分析了不同油藏類型的特點(diǎn),明確了不同油藏在凹陷的分布規(guī)律,對(duì)下步勘探具有一定指導(dǎo)意義。
[Abstract]:TN depression experienced the whole development process of Jurassic to early Cretaceous rift basin, and the unconformity surface was generally developed. Through the combination of well and earthquake, 12 different levels of unconformities were identified, including overlying unconformity, truncated unconformity, parallel unconformity and fold unconformity. The structure of unconformity is studied and the sealing or dredging action of unconformity interface is clarified. When unconformity and structure and fault are well matched the favorable traps can be formed. There are mainly four types of reservoirs related to unconformity, which are multi-layer superimposed reverse roof block reservoir, subaqueous fan tectonic-lithologic reservoir, sand body pinnacle reservoir and buried hill reservoir. The characteristics of different reservoir types are analyzed in combination with oilfield production practice, and the distribution of different reservoirs in the sag is clarified, which is of certain guiding significance for the next exploration.
