| 中文摘要: |
| 目前常用的古构造图的制作方法为“厚度图法”和“断层平移法”，这两种方法对断控圈闭为主的古构造恢复具有一定的局限性，且不能定量化的研究古构造生长发育情况。本论文首次将三维古构造恢复技术应用于珠江口盆地番禺-流花地区。三维古构造恢复技术在应用时，避免了厚度异常现象，实现了去压实恢复，能够更真实的反映古构造情况。该技术在珠江口盆地番禺流花地区“A”构造的应用，达到了定量化的分析古构造发育的效果，并且认识到了A构造在关键时期T32时期古构造幅度较小，后期构造幅度增大是A构造充满度过低的重要原因之一。 |
| 英文摘要: |
| The thickness method and fault-movement method, which are commonly utilized in paleo-structure restoration, have some limitations in the paleo-structure restoration of fault-controlled-predominant traps and they are unable to study the paleo-structure development quantitatively. This article applies 3D paleo-structure restoration technique in Panyu-Liuhua area, Pearl River Mouth Basin for the first time. This technique can avoid emerging thickness anomaly phenomenon and realize decompaction restoration, more really reflecting the paleo-structure. The application of this technique in Structure A achieves the results of analyzing paleo-structure quantitatively and unearth that Structure A had smaller relief in the critical time T32 and its relief enlarged later, which is regarded as a ciritical factor to lead to the very low hydrocarbon fullness in the president Structure A. |
