| 摘 要： | 以淀粉为主要原料，合成了新型多羟基糖苷防塌剂DTG-1。对合成样品的理化性能、页岩抑制作用、水溶液活度、生物毒性以及对泥页岩半透膜膜效率的影响规律进行了测定，考察了DTG-1在淡水、盐水和饱和盐水钻井液中对钻井液流变性能和滤失造壁性能的影响，并对DTG-1稳定井壁及改善钻井液流型的作用机理进行了分析。研究表明，用淀粉合成的多羟基糖苷，具有一定的抑制泥页岩水化膨胀、分散和提高泥页岩的膜效率的作用，能有效降低钻井液的水活度，属于无毒、环保型钻井液处理剂；DTG-1对高密度钻井液具有很好的流型改善作用，用DTG-1配制的钻井液具有组成简单、流变性易调整、高温稳定性好、抗污染性强等特点。

| Abstract: | Alkyl polyglucosides DTG-1 is synthesized with starch as the main raw materials. The performances of DTG-1, shale inhibition, water activity, toxidty, biodegradable property and its effect on shale membrane effidency and drilling fluid rheological and filtrating property are studied in lahoratory. The results show that DTG- 1 can inhibit the expansion and dispersion of shale in water, effectively decrease the water activity and improve shale membrane effidency. DTG- 1 is non-toxic and acceptable for environment provision. DTG 1 can improve the rheological properties of high density drilling fluids. The drilling fluid prepared by DTG- 1 has such advantages as simple formulation, easy rheolcgy adjttstment, high temperature stability and strong anti-pollution, etc. |
