Burial History of Stratigraphy and Maturity Evolution of Organic Matter in Manjiaer Depression Tarim Basin
-
摘要: 本文根据厚度恢复的体积模型，利用回剥方法，研究了满加尔凹陷寒武纪至第四纪的地层埋藏史，并根据初始沉积速率，将该区的地层埋藏史分为三个阶段。在地层埋藏史恢复基础上，结合ＴＴⅠ计算结果，分析了该区下古生界各生油层的生烃史和下奥陶统与中上奥陶统生油层最大可能生油气范围的发展演化。Abstract: In this paper, the burial history is recovered by using the back一tripping method according to thevolume model of thickness recovery from Cambrian to Quaternary in the Manjiaer depression, and it isdivided into three periods by means of the original sedimention rate On the basis of the recoery of burialhistory, the hydrocarbon evolution of source rocks in Lower Paleozoic is investigated in accordance withthe calculated results of TTI. The largest scope of hydrocarbon generation and their development are al-so discussed in this paper.
