Abstract Density, speed of sound, and viscosity of natural geothermal waters from the East Turkey Geothermal Field have been measured over the temperature range from 278 to 363 K and at atmospheric pressure. The measurements were made using the Anton Paar DSA 5000 M sound-speed analyzer and the Stabinger SVM3000 viscometer for two natural geothermal water samples from the Keklik Magarasi and Afyon wells. A sound-speed analyzer (Anton Paar DSA 5000 M) was used to simultaneously measure of the speed of sound and the density of the same geothermal water samples. The standard uncertainty of the density, viscosity, and speed of sound measurements is estimated to be 0.01%, 0.25%, and 0.05%, respectively. Measured values of density and speed of sound were used to calculate other derived key thermodynamic properties of the geothermal waters, which are very important for environmental impact optimization of a geothermal energy production operation. The properties measured at atmospheric pressure have been used as reference data for prediction of high-pressure properties of the geothermal waters.

测量土耳其东部地热水的密度、声速、粘度和衍生的关键热力学特性

摘要 来自东土耳其地热田的天然地热水的密度、声速和粘度已在 278 至 363 K 的温度范围内和大气压下进行测量。使用安东帕 DSA 5000 M 声速分析仪和 Stabinger SVM3000 粘度计对来自 Keklik Magarasi 和 Afyon 井的两个天然地热水样品进行了测量。声速分析仪（Anton Paar DSA 5000 M）用于同时测量相同地热水样品的声速和密度。密度、粘度和声速测量的标准不确定度估计分别为 0.01%、0.25% 和 0.05%。密度和声速的测量值用于计算地热水的其他派生关键热力学特性，这对于地热能源生产操作的环境影响优化非常重要。在大气压下测量的特性已被用作预测地热水高压特性的参考数据。
