摘要/Abstract

摘要： 本文用粘度、电导滴定、红外光谱、热重分析和热氧化发光等方法研究了四种分子链结构不同的泥浆处理剂的热稳定性.用这些处理剂调配的泥浆具有不同的抗温能力,实验结果说明处理泥浆的抗温能力与处理剂的分子结构有极密切的关系.

Abstract: The heat-stability of four kinds polyelectrolytes, HPAM, Spu(1), Na-CMC, and; FGLSwith different structures from each other, has been studied by the following methods: viscometry, conductimetric titration, IR, TGAand oxyluminescence.The changes of molecular weight and molecular structure, the results of TGAand the activation energies of oxidation as well showed that the heat-stabilities were in the following order:Spu(1)>FCLS>HPAM>Na-CMC.The heat-resistence of the drilling muds treated by these polyelectrolytes related closely to their structures.
