角度不整合面遮挡油藏数值模拟建模技术研究

The model technology research about simulation of the reservoir sheltered from the angular unconformity

角度不整合面遮挡形成的油藏与常规层状油藏的特点不同,研究内容及开发方式不同。这类油藏在不整合面处平面上向一个方向延伸,剖面上向倾向方向延伸,每个层无法象常规油层那样形成建模所需的构造顶面、储层分布等地质参数;因此,在地质建模研究方面采用与常规研究方法完全不同的特殊处理技术,从构造、储层及网格模型等多方面准确刻划了不整合面下油藏的地质特点,为类似油藏地质建模及油藏数值模拟技术的正确研究提供了技术依据。

The characteristic of the reservoir sheltered from the angular unconformity is different trom the nomal layer reservoir, its research contents and development fashion are different. At the place of unconformity, the reservoir extends towards one direction on surface and inclination direction on section. The geological parameters about structure map and reservoir distribution required by modeling fail to form like the general reservoir each layer. In the paper ,the special processing technology adopted completely is different from the normal research method in geological modeling research. It characterizes the geological features of the reservoir sheltered from the unconformity from structure, reservoir and grid model etc. This provides the technology reliance with the reservoir for the precise research of reservoir modeling and simulation.
