摘　　要：二连盆地乌兰花凹陷砂砾岩储层岩石矿物成分多样,孔隙结构复杂,常规电性特征难以反映储层流体性质,核磁共振测井一维流体识别方法存在较强多解性,油层与水层识别难度大。由此基于D-T2的二维核磁共振流体识别方法并同时考虑了储层流体的扩散和横向弛豫特征,减少了测井解释的多解性,并降低了二维核磁共振测井应用的作业与数据处理难度。该方法为准确识别复杂砂砾岩储层流体性质提供了有效手段,并为在更大范围内应用二维核磁共振油气层识别技术提供了可能。The glutenite reservoir in Wulanhua Sag of Erlian Basin is characterized by various mineral components and complex pore structure.The conventional electrical characteristics are difficult to reflect the fluid properties of the reservoir.The one-dimensional NMR fluid identification methods are of ambiguity,so it is difficult to distinguish oil and water layer.The D-T22D NMR method takes into account the diffusion and transverse relaxation characteristics of reservoir fluid,reduces ambiguity of logging interpretation,and reduces the operation and data processing difficulty of 2D NMR logging application.This method provides an effective means to accurately identify the fluid properties of complex glutenite reservoirs,and provides the possibility of applying 2D NMR reservoir identification technology in a wider range.
