The Hamar geothermal field is one of many low-temperature geothermal fields in Northern Iceland. Since 1966 eleven wells have been drilled in the field. The purpose of modelling the behaviour of geothermal field under a variety of exploitation schemes is to obtain knowledge of the physical processes needed for further exploitation, control and management.

The Hamar geothermal field is one of many low-temperature geothermal fields in Northern Iceland. Since 1966 eleven wells have been drilled in the field. The purpose of modelling the behaviour of geothermal field under a variety of exploitation schemes is to obtain knowledge of the physical processes needed for further exploitation, control and management. On the basic data of obseved water level, the physical behaviour of the Hamar geothermal field was simulated using a Lumped parameter model. Water level changes with varions production rates for the next 20 years are given. Conservative predicitous are obtained using closed models, and optimistic from open models.

冰岛北部Hamar地热田是一个低温地热田。1966年以来,已完成11口钻井。根据地热田温度、压力的观测数据,通过模拟方法,了解地热系统的物理状态和参数,可以为制定合理的长期开采、管理方案提供科学依据。本文采用一种集总参数模型模拟计算了地热系统的物理状态和参数。进一步预测了不同开采量条件下该地热系统的压力变化,提出了比较合理的开采方案。

Two low temperature geothermal fields in Iceland with calcite scaling in some wells are used for the study of calcite scaling potential.The results show that an allowable supersaturation without the precipitation of calcite scaling existed.The saturation index of 0 27 is the allowable supesaturation in low temperature geothermal wells in Iceland.This means that the geothermal water can contain 1.9 times more calcite in...

Two low temperature geothermal fields in Iceland with calcite scaling in some wells are used for the study of calcite scaling potential.The results show that an allowable supersaturation without the precipitation of calcite scaling existed.The saturation index of 0 27 is the allowable supesaturation in low temperature geothermal wells in Iceland.This means that the geothermal water can contain 1.9 times more calcite in solution than the theoretical amount.In addition,The results show that a high degree of calcite supersaturation in Hrisey well No.5 with calcite precipitation is mainly caused by mixing of the geothermal water from deep reservoir and cold water.

借助化学模型WATCH及VDATA程序,研究了冰岛低温地热水供热系统的碳酸钙沉积现象。结果表明,在地热水中允许存在一定的碳酸钙过饱和度,而不发生碳酸钙垢的沉积。饱和指数0.27为冰岛低温地热水中允许的碳酸钙过饱和度。即地热水中可以含有1.9倍理论量的碳酸钙。研究还发现,深层地热水与地表水的共混是导致本研究工作中Hrisey5号地热井碳酸钙高度过饱和,进一步引起碳酸钙沉积发生的主要原因

Geothermal resources are widely distributed in China. In recent years, a lot of research work has been carried out on the distribution, utilization, drilling, and exploration of geothermal resources. However, there is almost no record of geothermal reinjection in China. Based on geological characteristics, geophysical and geochemical features of Xi'an low-temperature geothermal field,this paper has established for the first time a 3-D numerical model to simulate the change of temperature and pressure after reinjection. The results show that making reinjection at the depth of 1 450 m to 2 300 m will benefit the reservoir pressure with no remarkable change in temperature.
