摘　　要：冀中坳陷潜山油气藏输导体系主要由断层、不整合构造和碳酸盐岩储集层构成。依据油气来源、供油方向及输导类型,可以将冀中坳陷潜山供烃方式分为源内供烃和源外供烃2大类,10种不同类型供烃方式。研究表明,断层和不整合面是该区潜山油气藏油气运移的主要通道,大多数潜山油气藏主要通过不整合和断层在差异压实作用下获得油气。Hydrocarbon transporting system in the buried hill reservoir of Jizhong Depression mainly involves faults,unconformity and carbonate rock.Based on the source of oil and gas,the direction of oil drainage as well as transporting type,the patterns of hydrocarbon supply in the buried hill of Jizhong Depression have been classified into two categories of inner-and outer-source supply which are subdivided into 10 types.The study shows that fault and unconformity had served as the main migration pathway in the buried hill reservoir.Most of the buried hill reservoirs had captured oil and gas through unconformity and fault by differential compaction.
