As shown in Figure 4(b-) and Figure 4(c-), the intrusion of organic solvent into the hardened cement slurry shows two to three signal peaks in the NMR relaxation spectrum.
Figures 4 (b-) and 4 (c-). Organic solvents invade the hardened cement slurry and exhibit two to three signal peaks in the nuclear magnetic relaxation spectrum.
As shown in Fig. 4 (B -) and Fig. 4 (C -), there are two or three signal peaks in NMR relaxation spectrum when organic solvent intrudes into hardened cement slurry.<br>
