摘要
WZ油田是苏北盆地高邮凹陷北斜坡东部2003年发现的新油田,最先发现的W2、W3断块的含油层系主要是古近系的阜三段(E1f3).本文通过对WZ油田E1f3砂岩储层"四性"关系及油水层的电性特征的分析研究,以取心、试油及测井曲线等资料研究了本区油干水层的识别标准,并对本区37口井油层的有效厚度进行了划分,取得了良好效益,为本区的新增探明储量及产能建设提供了有力基础.
The oilfield WZ is a new one found in the eastern part of the Gaoyou sag in the Subei basin in 2003. The oil-bearing formation of faulted blocks W2 and W3 is E1f3 in this oilfield. This article analyzed the “Four Qualities” relationship of sand reservoir E1f3 of oilfield WZ and the resistive features of oil, water, dry layers, studied the criteria for identification of oil, water, dry layers of reservoir E1f3 of oilfield WZ. This criterion was applied to recognition of net thickness of 37 wells, and proved very effective.
