摘要:
核磁共振T2譜包含儲層孔隙結構和流體的重要信息,通過對鄂爾多斯盆地不同地區不同層位核磁共振巖石物理實驗T2譜與核磁共振測井T2譜之間對應關系進行定性與定量研究,分析兩者展布區間、形態差異及束縛水飽和度在油氣生產過程中的意義,提出了一種基于實驗室核磁共振測量束縛水飽和度約束的T2,cutoff優化方法,有效解決了利用核磁共振巖石物理實驗標定核磁共振測井的難題,提高了核磁共振測井儲層評價的精度。
Abstract:
Nuclear magnetic resonance (NMR) T2 spectrum contains important information of reservoirs, such as pore structure and fluids. However, no effective solutions have been made on fully tapping the information of T2 spectrum and using the petrophysical data to calibrate NMR logging. Based on the qualitative and quantitative study of the correlation between the NMR petrophysical T2 spectra and the logging T2 spectra of rocks at different horizons in different areas of the Ordos Basin, the distribution range, morphological differences and the significance of irreducible water saturation in oil and gas production are analyzed. Finally, a T2,cutoff optimization method constrained by irreducible water saturation obtained in laboratory NMR measurement is proposed. This method can effectively facilitate the NMR logging calibration by NMR petrophysical experiment, and improve the accuracy of reservoir evaluation by NMR logging.
