摘　　要：留58潜山蓟县系雾迷山组油藏为块状裂缝性灰岩油藏,储层空间类型包括了原生孔隙,溶蚀孔隙,以及裂缝等类型。潜山储层物性的分布特点表现为纵向上的分层发育和横向上的分带发育。综合本区测井解释及岩心观察认为,影响潜山储层发育的因素包括储层岩性,纵向上不同储层段与内幕隔层的配置关系,以及平面上储层发育带是否处于潜山构造顶部或断层破碎带等。通过对留58潜山储层非均质性特征的研究,总结了该区储层发育规律,为后期油藏的合理开发提供科学依据。Reservoir of the Wumishan Formation of the Jixian System in the Liu 58 buried hill is a massive is a massive and fissure limestone one. Reservoir space includes primary pore, dissolution pore and fissure. Reservoir physical property is characterized by vertically bedded and horizontally banded development. Logging and core observation indicate that development of the reservoir is dependent on lithologic character, reservoir-caproek association pattem and relation of reservoir with buried hill structure. This paper deals with reservoir inhomogeneity in the Liu 58 buried hill and reservoir development regularities, providing scientific base for reasonable development of petroleum reservoir.
