摘要： 通过低场核磁共振实验分析了柴达木盆地涩北地区第四系泥岩型生物气储层在饱和水状态及渐变烘干温度状态下的T2谱，明确了孔隙流体的核磁响应特征，以评价孔隙的有效性。研究结果表明： ①核磁共振实验是以饱和水状态T2谱为基础，采用正态分布函数拟合构建了离心束缚水T2谱，确定了可动流体和毛管束缚流体T2截止值，用于划分出流体类型并开展了孔隙有效性评价。②研究区岩样饱和水状态T2谱谱峰呈左小右大的形态，右峰幅度值远大于左峰，占T2谱幅度值90%以上；随着烘干温度的升高，T2谱幅度减小且左移趋势明显；束缚水T2谱形态近似于正态分布，起始位置与饱和水状态的T2谱基本重合。③研究区可动流体T2截止值T2 C1平均为3.3 ms，毛管束缚流体T2截止值T2 C2平均为1.8 ms；孔隙流体包括可动水、毛管束缚水和黏土束缚水，黏土束缚水T2小于T2 C2，毛管束缚水T2大于T2 C2且小于T2 C1，可动流体T2大于T2 C1；毛管束缚水含量最高，黏土束缚水其次，两者占总孔隙流体的84.43%～95.06%，可动水含量低。④研究区储层有效孔隙占总孔隙的54.99%，主要为毛管束缚孔，黏土束缚孔为无效孔隙；黏土含量越高，有效孔隙度越小。

Abstract: Through low-field NMR experiments, the T2 spectra of the Quaternary mudstone biogas reservoirs in the Sebei area of Qaidam Basin were analyzed under saturated water state and gradient drying temperature state, and the NMR response characteristics of pore fluids were clarified to evaluate the effectiveness of pores. The results show that:(1) Based on the T2 spectrum under the saturated water state, the centrifugal bound water T2 spectrum was constructed by fitting the normal distribution function, the T2 cutoff values of movable fluid and capillary bound fluid were determined, the fluid types were divided, and the pore effectiveness evaluation was carried out. (2) The T2 spectral peaks of water-saturated rock samples in the study area are small on the left and large on the right, and the amplitude of the right peak is much larger than that of the left peak, accounting for more than 90% of the T2 spectral amplitude. With the increase of drying temperature, the amplitude of the T2 spectrum decreases and the left shift trend is obvious. The T2 spectrum shape of the bound water is approximately normal distribution, and the starting position basically coincides with the T2 spectrum under the saturated water state.(3) The T2 cutoff value(T2 C1) of movable fluid in the study area is 3.3 ms on average, and the average T2 cutoff value(T2 C2) of capillary bound fluid is 1.8 ms. The pore fluids include movable water, capillary bound water and clay bound water. The clay bound water T2 is less than T2 C2, and the capillary bound water T2 is larger than T2 C2 and less than T2 C1, and the movable fluid T2 is larger than T2 C1. The capillary bound water content is the highest, followed by the clay irreducible water, which account for 84.43%-95.06% of the total pore fluids, and the movable water content is low.(4) The effective pores of the reservoir in the study area account for 54.99% of the total pores and are mainly capillary-bound pores, and clay-bound pores are ineffective pores. The higher the clay content, the smaller the effective porosity.
