巨厚变质岩潜山油藏立体开发开发阶段划分

Phase division of tridimensional development for metamorphic rock buried hill reservoir with huge thickness

油藏立体开发是一种新型开发模式,立体开发开发阶段划分更需探索研究。以辽河油田兴古7区块为例,在地质建模基础上,运用数值模拟方法,评价历史拟合结果,分析油藏外在开发指标特征与内在渗流机理的联系,研究巨厚变质岩潜山油藏立体开发的各项指标变化,从指标变化节点将立体开发划分为5个阶段,建立各个阶段技术指标界限标准。此研究对巨厚变质岩潜山油藏立体开发具有指导意义。

Since the tridimensional reservoir development is a new development mode,it is necessary to study on its phase division. Taken Xinggu 7 block in Liaohe Oilfield as an example,based on geological modeling,the history fitting results were evaluated by using numerical simulation. And then the relationship between development index and percolation mechanism was analyzed. It was studied on the changes in various indexes for the tridimensional development of the metamorphic rock buried hill reservoir with huge thickness. According to the change nodes of indexes,the tridimensional development was divided into five phases. The threshold standards of technological indexes at various phases were built to provide a theoretical guide for the tridimensional development of the metamorphic rock buried hill reservoir with huge thickness.
