摘　　要：华北探区深潜山储层主要以雾迷山组灰质白云岩和奥陶系灰岩为主,储层裂缝孔洞的不均匀发育,导致储层的非均质性较强,通过研究认为华北探区深潜山储层主要发育裂缝孔洞系统,而随着储层裂缝孔洞发育程度和连通程度的不同,测试曲线呈现均质径向流动特征、双重介质流动特征和致密的基质孔隙型流动特征,通过对测试曲线特征的研究,可对白云岩、灰岩的裂缝孔洞发育和连通程度做出判断,从而加深储层认识,指导下步措施决策。Deep buried hill type reservoirs in Huabei exploration area mainly belong to Wumishan group limy dolomite and Ordovician limestone. Fracture-vug of these formations shows uneven development, leading to strong heterogeneity. This study shows that formation of deep buried hill type reservoir in Huabei exploration area are mainly fracture-vug, for which well testing curve shows characteristics of radial flow, double porosity and tight matrix porous flow due to the difference in fracture-vug and connectivity of formation. This study on characteristics of well testing curve is useful for determining the fracture-vug and connectivity of dolomite and limestone, which can lead to a deep understanding about formation for guiding further steps.
