摘要
通过盆地构造单元的划分能够揭示盆地内部基本构造特征,明确基础地质认识,是含油气盆地分析的基础工作。在已划分构造单元的基础上,进而研究该地区油气成藏模式,对于有利区带的预测,指导油田下一步勘探有重要意义。在调研前人对构造分区的划分依据及划分方案后,发现将盆地源岩构造高部位和构造低部位结合起来进行构造单元划分,更能明确该地区油气运聚模式,清晰源岩与已发现油藏的分布相关性。
The basic structural features of the basin and the basic geological knowledge can be revealed by the division of basin tectonic units. On the basis of the structural units, it is of great significance to study the oil and gas accumulation model in this area, to forecast the favorable zone and to guide the next exploration of the oilfield. It is found that the combi- nation of the high and low parts of the source rock in the basin is used for the division of tectonic units, which can make clear the oil and gas migration and accumulation pattern in the region and the distribution correlation between the source rock and the discovered reservoir.
