摘　　要：以锦州南潜山油藏为例,依据钻井取心、露头、化验分析资料以及试油和生产等动态资料,研究了渤海湾盆地上太古界潜山油藏岩性特征、储集空间类型和影响因素,认为最有利的岩石类型依次是黑云二长片麻岩、二长片麻岩、角山花岗片麻岩、黑云斜长片麻岩、花岗片麻岩,最不利的岩石类型依次是石英伟晶岩、正长伟晶岩和花岗伟晶岩;主要的储集空间类型包括风化淋滤孔、溶蚀孔、风化缝、构造缝、区域缝等;影响储集物性的主要因素是风化作用、岩性、古地貌和断裂作用。本文研究结果对于渤海湾盆地上太古界潜山油藏钻井部署具有一定的指导作用。Based on drilling core,outcrop,laboratory analysis data and dynamic data like oil test and production performance,lithologic characteristics,reservoir space types and influencing factors of Upper Archean buried hill reservoir in the Bohai Bay basin were studied by taking the Southern Jinzhou buried hill reservoir as an example.The studies suggest that the most favorable rock types are biotite two-feldspar gneiss,two-feldspar gneiss,horned granitic gneiss,biotite plagioclase gneiss and granitic gneiss successively,and the most unfavorable rock types are quartz pegmatite,syenite pegmatite and granitic pegmatite successively;the main reservoir space types include weathered leaching pores,dissolution pores,weathering fractures,structural fractures,regional fractures,etc..The main factors affecting reservoir properties are weathering,lithology,paleogeomorphology and faults.The results of this paper will provide a guidance for the drilling deployment in the Upper Archean buried hill reservoir of Bohai Bay basin.
