| 摘 要： | 通过对实验室压汞资料和核磁共振测量资料的对比分析,利用确定压汞孔径分布曲线孔径rc左右边界的方法确定核磁共振T2谱与孔喉半径rc的横向转换系数,利用改进二维分段等面积刻度方法确定其纵向转换系数,使得计算得到的伪毛管压力曲线与实验室压汞测量的毛管压力曲线基本一致。另外,对各种转换系数进行建模,实现在无实验室压汞资料情况下获得定量、连续、高精度的伪毛管压力曲线和孔隙结构参数。将研究成果用于复杂储层评价中,可进行储层分类和估算产能。

| Abstract: | According to the comparison between mercury penetration and NMR logging data,the horizontal conversion coefficients between magnetic resonance T2 spectrum and pore throat radius rc are determined by pore size distribution curve of mercury left and right borders,furthermore,the vertical scale conversion coefficients is determined by the improved two-dimensional section equal area method,and then the pseudo-capillary pressure curves determined by magnetic resonance T2 spectrum are almost the same with the res... |
