| 摘 要： | 本文研究了改性沥青(K-AHM)与改性淀粉(S-P)对页岩的稳定作用。实验结果表明,不论是室温还是加温的情况下,K-AHM对页岩膨胀的抑制作用均好于S-P。通过红外光谱与等温吸附实验证明,K-AHM抑制页岩膨胀是因为它能吸附到页岩表面上,形成一层较厚的疏水膜,从而防止水分进入页岩。

| Abstract: | The stabilization of shales by modified asphalt (K-AHM) and modified starch(S-P) was studied. The experiment results showed that the stabilization .by K-AHM was better than that by S-P at both normal temperature and elevated temperature. Infra-red spectroscopy and adsorption isotherm proved that K-AHM could inhibit shale swelling, because of its molecular tadsorption on the suriaee of shales. A hydrophobic film thus formed on the shale surface could prevent water from entering into shales, |
