摘要
渤中地区第三系主要含油层位储层类型丰富.通过测井、岩心和实测资料分析,探讨了不同层段储层的沉积学、非均质性、成岩作用和物性等特征.馆陶组储层为河流沉积体系,砂体规模大,砂岩结构成熟度较高,成岩作用相对较弱,是渤中地区最为有利的储层.东营组储层以东北部大型三角洲沉积体系为主.沙河街组储层以扇类沉积体系为主,地层埋藏深,砂体分散、规模小,储层质量差.
There are various types of reservoir in the main oil bearing formations of Tertiary in Bozhong area. Based on data of logging, core and experiment, sedimentology, heterogeneity, diagenesis and petrophysics have been discussed for these reservoirs in different formations. The fluvial reservoir in Guantao Formation has the greatest exploration potential in Bozhong sag because it is large in sandbody size, high in sandstone texture maturity and weak in diagenesis. The Dongying Formation reservoir is predominated by a northeast large delta, and the Shahejie Formation reservoir, chiefly composed of a fan system, is poor in petrophysical properties due to deep burial and dispersive and small sandbodies.
