摘　　要：大港油田张东地区沙河街组沉积物主要来自埕宁隆起,储层岩性主要以细砂岩为主,中砂岩、粉砂岩、含砾砂岩次之。本文利用测井、录井、岩心和试油等资料对沙二段储层的岩性、物性、电性及含油性特征进行深入研究,揭示了四性之间的关系,确定了该段油、气、水层各自的电性特征,储层有效厚度划分的物性、岩性、含油性与电性下限,以及油、水、干层识别图版,对今后油田开发工作有重要指导意义。Deposition of Shahejie in Zhangdong area of Dagang Oilfield mainly comes from Changling uplift . Its reservoir lithology consists mainly of packsand , secondly of mediμm sand , siltstone and pebbled sandstone,This paper studied reservoir lithology, poroperm characteristics, petroliferous properties and electric properties of the second member of Shahejie formation by the analysis of well logging, log, core and production testing . It revealed the four-property-relationship and defined each electric properties of oil,gas and water layers, It defined the lower limit of effective thickness of lithology, poroperm characteristics, petroliferous properties and electric properties ,and made a identification plate of oil, water and dry layers,It has an important guiding significance on development of the oilfield in the future.
