摘　　要：港172断块是大港油田港西北斜坡上的一个含油断块,主要目的层为沙三段Ⅱ油组(Es3Ⅱ)的重力流水道砂岩。运用储层地质学理论,利用钻井、岩心分析、测井解释资料,对港172断块Es3Ⅱ油组储层展布和储层物性的空间变化规律进行分析、描述,达到充分认识港172断块Es3Ⅱ油组储层特征的目的。同时,结合构造研究和试油、试采流体分析数据,确定了港172断块Es3Ⅱ油组的油藏类型。该研究成果为储层地质建模和区块开发调整提供了地质依据。Block Gang172 is an oil-bearing block on the northwest slope of Dagang Oilfield, with Es3Ⅱ oil unit of gravity-flow channel sandstone at the main target. Reservoir geology and data of drilling, core analysis and logging interpretation are used to analyze and describe reservoir distribution and spatial change of petrophysical properties in Es3Ⅱ oil unit of Block Gang172. In conjunction with structural study and fluid analysis data from oil testing and production test, the type of reservoirs in Es3Ⅱ oil unit of Block Gang172 are determined. The result of this study has provided geological basis for reservoir modeling and development adjustment.
