为了能够准确地评价储集层及油气资源，分析岩石物性参数和孔隙流体性质具有十分重要的意义。核磁共振录井技术可以在录井施工现场快速、准确、连续分析储层物性，三次测量后得到的T2弛豫图谱可以反映储层孔隙流体信息，提供孔隙度、渗透率、含油饱和度以及可动流体饱和度等评价参数；将参数与T2弛豫图谱相结合，参照测井以及试油情况等资料，在某油田定性识别5口井，核磁共振录井解释与试油结论基本相符。因此，利用核磁共振T2弛豫图谱与分析参数可以有效地定性评价储集层，为油田的勘探开发提供基础资料和数据。

In order to evaluate reservoir stratum and oil and gas resources accurately, it is of great significance to analyze physical parameters and porosity fluid properties of the rock. Nuclear magnetic resonance logging technology can fast, accurately and continuously analyze reservoir physical property in logging site. The T₂ relaxation spectrum obtained after measurement three times can reflect the reservoir porosity fluid information and provide evaluation parameters such as porosity, permeability, oil saturation and movable fluid saturation. The parameters are combined with T₂ relaxation spectrum, qualitatively identified are 5 wells in an oil field according to the logging and oil testing data and the nuclear magnetic resonance logging interpretation is basically consistent with the oil testing conclusions. The reservoir can be qualitatively evaluated effectively by using T₂ relaxation time spectrum and the parameters, which can provide some basic information and data for exploration and development of oil fields.
