利用13个溶质（Na/K）温度计和21个气体温度计对世界上10个重要地热系统的深部储层温度进行了估算。综合评价了预测温度，并与利用地球化学计量技术测得的井底温度进行了比较。研究结果表明：（1）大多数Na/K地质温度计对大多数以液态为主的地热田具有较高的预测性能，而对以气态为主的高温地热田则表现出较低的预测性能;（2）在高温地热系统中，气体温度计比Na/K温度计更能成功地预测地下温度;（3）Na/K地热温度计对地热系统的预测性能高，气体地热温度计对地热系统的预测性能低，反之亦然：（4）Na/K地热温度计和气体地热温度计对大多数低焓地热田的储层温度普遍高估，对大多数高焓地热田的储层温度普遍低估;（5）气体温度计预测的储层温度比Na/K温度计预测的储层温度更分散，（6）Na/K温度计在预测储层温度方面比气体温度计更成功。
Deep reservoir temperatures of 10 important geothermal systems of the world were estimated by applying 13 solute (Na/K) and 21 gas geothermometers. The predicted temperatures were comprehensively evaluated and compared with measured bottom-hole temperatures using geochemometric techniques. The present study reveals (1) high prediction performances in most of the Na/K geothermometers for the majority of the geothermal fields with liquid-dominated reservoirs, whereas low prediction performances were indicated for the geothermal fields with vapour-dominated and high-temperature reservoirs; (2) the gas geothermometers, in comparison to Na/K, are more successful in predicting the subsurface temperatures in high-temperature geothermal systems; (3) the geothermal systems for which Na/K geothermometers have indicated a high prediction performance, the gas geothermometers have specified a low prediction performances, and vice versa; (4) both Na/K and gas geothermometers, generally, overestimated the reservoir temperatures for the majority of the low-enthalpy geothermal fields and underestimated for the majority of the high-enthalpy geothermal fields; (5) the reservoir temperature predictions of gas geothermometers have more scatter than those temperatures inferred from Na/K geothermometers; and (6) in general, Na/K geothermometers seem to be a more successful geochemical tool in predicting reliable reservoir temperatures than gas geothermometers.
