摘要:

探讨了成藏作用的研究对象、研究思路和模拟技术,同时选取海拉尔盆地乌尔逊凹陷北部苏仁诺尔含油气构造为模拟对象,建立了相应的地质模型,并进行了成藏作用模拟。认为该区烃源岩经历了3个热演化阶段,即伊敏组沉积期前、伊敏组沉积期和贝尔湖群沉积期,对应有3个生烃高峰期和3个成藏期,伊敏组沉积期是油气聚集的关键时期。认为根据生烃作用、成藏模拟、包裹体分析和圈闭发育史分析,可以深入探讨油气形成与富集规律。

关键词: 成藏作用, 地质模拟, 生烃高峰, 关键时刻

Abstract:

In order to study hydrocarbon accumulation, the studying object, the train of thought and the technique of modeling are discussed. As an example, the hydrocarbon accumulation of north of Wuerxun depression is modeled after the geological model is established. The result is that the source rocks suffered three main periods of hydrocarbon generation and accumulation, but the second is the key of hydrocarbon generation and accumulation. After the hydrocarbon accumulation modeling, the process is reconstructed and it is easier for the key to be ascertained.We can go deep into discussing the hydrocarbon accumulation.

Key words: Hydrocarbon accumulation, Geological model, Main period of hydrocarbon generation, Key period of hydrocarbon accumulation.
