冰岛北部Hamar地热田开采模型

EXPLOITATION MODEL OF THE HAMAR GEOTHERMAL FIELD, NORTHERN ICELAND

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。

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.
