摘要
对古城油田X区块核三段Ⅳ、Ⅴ、Ⅵ油组沉积相进行研究。从泌阳凹陷整体出发,通过岩心颜色、岩性、构造、层理分析,结合测井相、单井沉积微相分析和骨架井联井剖面相研究,认为研究区以扇三角洲前缘亚相沉积为主,发育水下分流河道、河口砂坝、席状砂、分流间湾微相。最终建立了研究区的沉积相模式。
The authors analyze the sedimentary facies in the oil group of Ⅳ,Ⅴand Ⅵ of H3 Member in the Gucheng oil filed.Based on the analysis of the whole Biyang depression,they describe the drilling core from many aspects,such as the rock colour,lithology,structure,and beding.Combined the well logging facies analysis,and through the analysis of single well microfacies and sections of united wells,the authors consider that the region of interest belongs to be sub-facies deposition of the front fan delta.They subdivide the precipitation facies into the microfacies of underwater distributary channel,river mouth bar,sheet sand and interdistributary bays.The authors establish the depositional model of the region of interest.
