Abstract
Reservoir temperature is a key parameter for genesis analysis, potential evaluation and research of waterrock interactions of geothermal systems. It is necessary to identify the suitable geothermometer for a certain geothermal field for better characterization of the geo-temperature field. In this paper we attempt to determine the most suitable geothermometer applied to the Tianjin Geothermal field, Bohai Bay Basin, China by a systematic sampling and analysis of the water samples collected from five sandstone and carbonate geothermal reservoirs during year 2009 to 2010. Results show that most of the water samples are not in full equilibrium with the reservoir rock indicated by the Giggenbach triangular diagram and thus cation geothermometers cannot be applied, while chalcedony geothermometer instead of the other quartz varieties is found to be the most suitable one based on saturation index calculation. The temperature predicted are ±5ºC compared to that of the well head temperature, and the reservoir temperature of the Tianjin geothermal filed is estimated to be less than 100ºC, falling into the low to medium temperature Range.
