摘要： 在岩心观察和沉积相分析基础上，利用大量的岩石薄片、铸体薄片、孔渗物性和压汞参数等资料，系统讨论了黄骅坳陷塘34断块古近系沙河街组一段下部储集层特征及影响储集层储集性能的主要地质因素。认为塘34断块沙一段下部储集层为中低孔、低渗特低渗、细喉储集层。储集层物性主要受成岩作用以及砂泥岩组合方式等因素控制，其中碳酸盐胶结物、硅质胶结物及黏土矿物转化是造成储集层物性变差的主要原因；而溶蚀作用控制次生孔隙发育程度，提供有利储集空间，储集层段的自生高岭石是长石和岩屑溶蚀的产物；砂泥岩组合方式则控制着储集层物性纵向上的分布规律。

Abstract: Based on core observation and sedimentary facies analyses，the reservoir characteristics of the lower part of Member 1 of Paleogene Shahejie Formation in Tang 34 Block and the main geological factors influencing its physical properties are systematically studied by using a large number of rock thin sections，thin sections，porosity and permeability properties and mercury-injection data, etc.The results indicate that the lower part of Member 1 of Paleogene Shahejie Formation reservoir belongs to middle to low porosity，low to extra-low permeability and fine throat reservoir.Reservoir properties of the study area are dominated by diagenesis，and combination pattern of sandstone and mudstone.Among them，carbonate cement，silica cement and clay mineral transformation are the main factors leading to the poor physical properties，while the corrosion produces substantial secondary porosity and provides favorable reservoir space.Authigenic kaolinite is the dissoluted product of feldspar and debris.Vertical distribution of reservoir properties are controlled by combination of sandstone and shale.

Key words: Huanghua Depression, Paleogene, Shahejie Formation, reservoir property, controlling factors
