以葡萄糖与三甲基氯硅烷为原料合成三甲基硅烷基葡萄糖苷(TSG),考察了TSG对膨润土线性膨胀率的影响,并通过泥球实验和防膨实验进一步考察了TSG对粘土水化膨胀、分散的抑制作用。实验结果表明:TSG具有较好的抑制粘土水化膨胀、分散的作用。在质量分数为10%的TSG水溶液中,膨润土的线性膨胀率仅为54.62%,防膨率为79.07%。在TSG水溶液中浸泡的泥球水化膨胀程度明显降低。室温下,TSG对水基钻井液有增粘作用,滤失量较基浆得到了一定的控制,且摩阻系数降低。

Trimethylsilyl glucoside ( TSG) was synthesized with glucose and chlorotrimethylsilane as raw materials .The influence of TSG on bentonite linear expansion rate was investigated ,and the inhibition of TSG to clay swelling was exam-ined by the mud balls and anti -swelling experiments .The results showed that the TSG has a good inhibition to the hydra-tion swelling and dispersion of clay .The linear expansion rate of bentonite and the anti -swelling rate were only 54.62%and 79.07%respectively in a 10%concentration of TSG aqueous solution .The hydration expansion degree of the mud ball in the TSG solution was significantly reduced .At room temperature , viscosity of the water -based drilling fluid was in-creased ,the filter loss was lower than the base slurry ,and friction coefficient was reduced after adding TSG .
