具有易水解官能团的有机化合物具有成为热敏示踪剂的潜力。为了扩大低焓地热储层中遇到的典型温度下可用化合物类别的范围，对氨基甲酸酯组进行了研究。采用恒温间歇实验法研究了8种伯氨基甲酸酯和1种仲氨基甲酸酯的动力学参数。考察了化合物结构、温度、pH/pOH等因素对水解动力学的影响。结果表明，这些示踪剂在很宽的温度范围内的可能的应用。
Organic compounds with functional groups susceptible to hydrolysis hold the potential to become thermo-sensitive tracers. To broaden the range of available compound classes for typical temperatures encountered in low enthalpy geothermal reservoirs, the group of carbamates was investigated. The kinetic parameters of eight primary and one secondary carbamate(s) were studied by means of isothermal batch experiments. The influence of several parameters on hydrolysis kinetics was investigated, which included the compound structure, temperature, and pH/pOH. The results demonstrate the possible application of these tracers within a broad range of temperatures.
