苏北盆地层序地层划分与砂岩储层预测研究
Research on sequence stratigraphy and reservoir prediction in the Dainan Formation of eastern Gaoyou Sag in the Subei Basin
摘要
Abstract
This study aims to predict subtle reservoirs in the south terrace of the Subei Basin in the East China Sea, according to the theory of sequence stratigraphy, and taking the rise-to-fal base-level turnaround point as the interface of the sequence units. From the lithologic and logging data, two long base-level cycles, seven medium base-level cycles, and a number of short base-level cycles are recognized in the Dainan formation. A high resolution stratigraphic frame has been built up in order to predict the distribution of sandstones in the reservoir of the Fuminzhuang area, which is located in the south terrace of Gaoyou Sag, by analyzing sand thickness, which is controled by the base-level. The good reservoirs are mainly concentrated in the lower section of the Dainan formation (rising half a cycle early in the MSC1 period) and the upper section of the Dainan formation (faling half a cycle late in the MSC6 period), respectively as "1" or "L" type distribution in the Fuminzhuang area. These results are very important for ifnding good reservoirs in the petroleum basins in the east of China.关键词
