摘要
核磁共振测井仪器可以实现自旋核的极化、把体磁化强度M0 扳倒在与B0 垂直的平面上、自旋回波探测;回波串的衰减率反映了地层的孔径尺寸信息和流体类型信息,核磁共振技术在油田测井中得到了广泛应用,在油田储层评价中具有重要价值.
Abstract
Nuclear magnetic resonance well logging tool polarizes the spins,rotates bulk magnetization vector M0 to the transverse plane which is perpendicular to B0,detects the echo train.Attenuation rate of the echo train indicates the diameter of formation pore and what kind of fluid in the pore.Nuclear magnetic resonance well logging tool has been widely used in petroleum exploration,logging data interpretation is very valuable for the evaluation of reservoir formation.
