西加盆地Cardium组薄砾岩储层水驱可行性分析
Analysis of waterflood feasibility for the thin conglomerate reservoir of Cardium Formation,Western Cana-da Basin
摘要
Abstract
In order to make clear the waterflood development potential of the thin conglomerate reservoir named Cardium A in Cardium Formation of Western Canada Basin,the reservoir type was classified ac-cording to the core observation,mercury injection and phase permeability experiments.The waterflood development effect was analyzed based on the data from the field water injection test.The results show that the conglomerate reservoir can be classified into type Ⅰ pure conglomerate and type Ⅱ impure con-glomerate.The well productivity is controlled by the conglomerate reservoir type and reservoir thick-ness.The field water injection can hardly form extensive and effective waterflood channels due to the heterogeneity and rapid rock face changes of the conglomerate reservoir.The producer dynamic respon-ses present the type of quick water breakthrough and the type of slight influence.The numerical simula-tion of waterflood shows that the total oil increase of the gentle water injection scenario is larger than that of the enhanced water injection scenario.The oil increase of water injection scenarios is little com-pared with that of the scenario without water injection.This research confirms that the waterflood feasi-bility for Cardium A,the thin conglomerate reservoir,to increase oil production is quite low,which also provides references for water injection development of other similar reservoirs.关键词
