Abstract

Mineral precipitates along thermal fluid pathways (scaling) and clogging by unconsolidated grains inversely affect the efficiency of geothermal systems. An experimental approach is presented to quantify dissolution-precipitation processes in fractured, geologically complex carbonate rocks of Devonian age. The outcome suggests that the dissolution-precipitation processes must be placed in the context of different fluid properties and pressure conditions between the injection and the production well. A geochemical monitoring program documenting the processes in the carbonate aquifer rocks is presented. Experimental work must be combined with field and modelling approaches to unfold its full strength.

断裂地热碳酸盐储层岩石中的缩放：实验方法

热流体通道上的矿物沉淀（结垢）和未固结颗粒的堵塞会对地热系统的效率产生反向影响。本文介绍了一种实验方法，用于量化泥盆纪断裂、地质复杂的碳酸盐岩中的溶解沉淀过程。研究结果表明，溶解-沉淀过程必须结合注入井和生产井之间不同的流体性质和压力条件。本文介绍了一项地球化学监测计划，该计划记录了碳酸盐含水层岩石中的过程。实验工作必须与现场和建模方法相结合，才能充分发挥其优势。

期刊介绍： Geothermics is an international journal devoted to the research and development of geothermal energy. The International Board of Editors of Geothermics, which comprises specialists in the various aspects of geothermal resources, exploration and development, guarantees the balanced, comprehensive view of scientific and technological developments in this promising energy field. It promulgates the state of the art and science of geothermal energy, its exploration and exploitation through a regular exchange of information from all parts of the world. The journal publishes articles dealing with the theory, exploration techniques and all aspects of the utilization of geothermal resources. Geothermics serves as the scientific house, or exchange medium, through which the growing community of geothermal specialists can provide and receive information.
