| 摘 要： | 以六甲基二硅氮烷(以下称有机硅)、苯基有机胺、羧甲基淀粉等为原料,制备出一种油田钻井液用抗165℃高温的有机硅改性阳离子淀粉降滤失剂(OSCS)。FT IR结果显示,羧甲基淀粉(CMS)结构上引入了苯基阳离子和有机硅基团。用差热分析考察其热稳定性,结果表明,OSCS的热分解温度为262℃。用高温滚子加热炉和中压滤失量测定仪等钻井液专用仪器,考察了OSCS的钻井液性能,结果显示,在170℃高温滚动16h后较高温滚动前,API滤失量略有增加。因此所合成的有机硅改性苯基阳离子淀粉降滤失剂OSCS在170℃高温下具有良好的耐热稳定性,适用于井底温度低于170℃的深井钻探。

Synthesis and Properties of High Temperature-resisting Organsilicone Modified Cationic Starch Filtrate Reducer |
| |
| Abstract: | A novel organsilicone-modified cationic starch filtrate reducer(OSCS) was prepared from hexamethyldisilazane,phenyl amine,carboxylmethyl starch(CMS) etc.The filtrate reducer with high temperature-resistant capability was used for drilling fluid.FT IR indicated that both the phenyl cation group and organic silicon functional group were introduced into the structure of carboxymethyl starch(CMS).Furthermore,its thermal stability was characterized by TG-DTA,showing that the decomposition of OSCS was 262℃.The properties of OSCS drilling fluid were studied by portable roller oven and API filter press.The results revealed that the amount of API filtration of OSCS increased slightly after aging 16 h at 170℃.Therefore,the obtained OSCS product has excellent thermal stability and it can be used for deep well drilling below 170℃. |
