首次研究了端胺基聚酰胺-胺（PAMAM）树枝状大分子作为页岩稳定剂的应用。通过膨润土抑制试验和泥质岩屑分散试验，对其抑制性能进行了表征。采用X射线衍射（XRD）、傅里叶变换红外（FT-IR）、透射电镜（TEM）和热重分析（TGA）等方法研究了不同代PAMAM树枝状大分子与钠基膨润土的相互作用。PAMAM树枝状大分子能有效抑制页岩水化分散。树枝状聚合物水溶液pH值的降低提高了其缓蚀性能。对于较低代的树枝状聚合物生长（G 0至G3），抑制水平随着代的增加而降低。在较高世代（G4、G5），抑制水平随世代的增加而增加。低代PAMAM树枝状大分子可以渗透到粘土层间空间，但表现出高度扁平的插层行为。随着浓度的增加，G 0以单层结构嵌入层间，而G1、G2、G3和G4在低浓度时以单层结构嵌入层间，在高浓度时以混合相取向嵌入层间。G5由于空间位阻的作用不能完全插入层间空间。根据PAMAM与粘土之间的相互作用，低代G 0和高代G5相结合可有效抑制泥页岩水化分散。以G 0为泥页岩膨胀抑制剂，G5为泥页岩分散抑制剂，研制出了一种新型水基钻井液体系。
The amine terminated polyamidoamine (PAMAM) dendrimers were investigated as potential shale stabilizers for the first time. Its inhibitive properties were characterized by a bentonite inhibition test and a shale cuttings dispersion test. The interaction between PAMAM dendrimers of various generations and sodium bentonite was examined by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, transmission electron microscopy (TEM) and thermogravimetric analysis (TGA). The hydration and dispersion of shale can be effectively inhibited with PAMAM dendrimers. The decrease of pH value in the dendrimer aqueous solution improved the inhibitive performance. For lower generations of dendrimer growth (G0 to G3), the inhibitive level decreased with the increase of generation. For higher generations (G4, G5), the inhibitive level increased with the increase of generation. Low generation PAMAM dendrimers could penetrate into the clay interlayer space, but exhibited highly oblate intercalation behaviors. G0 intercalated into the interlayer space with a monolayer conformation as concentration increased, while G1, G2, G3 and G4 intercalated into the interlayer space with monolayer arrangement at low concentrations, and mixed phase orientation at high concentrations. G5 could not fully intercalate into the interlayer space due to the steric hindrance. According to the interaction between PAMAM and clay, effective internal and external inhibition on shale hydration and dispersion could be obtained with the combination of low generation G0 and high generation G5. A new water-based drilling fluid including G0 as shale swelling inhibitor and G5 as shale dispersion inhibitor was established and exhibited excellent inhibitive properties.
