摘要

奥克兰大学多年来一直与Contact Energy Limited（及其前身）合作开发Ohaaki地热田的计算机模型。本文描述了过去4年来开发的最新模型。它基于一个更新的数字概念模型，该模型与我们的建模框架一起用于建立油藏模型，该模型可以在AUTOUGH2（我们著名的模拟器TOUGH2的版本）或Waiwera（我们自己的高度并行模拟器）中运行。新的数字概念模型改进了地质构造、断层和蚀变带的表示，相应的数值模型对大部分数据的拟合得到了改进。在怀卡托河西岸的BR59、BR60和BR61等深井中，新模型对温度下降和压力下降后的压力恢复有更好的结果。

An updated model of Ohaaki geothermal field, New Zealand

The University of Auckland has been collaborating with Contact Energy Limited (and its predecessors) for many years on computer modelling of the Ohaaki Geothermal Field. This paper describes the latest model that has been developed over the last 4 years. It is based on an updated digital conceptual model that is used, with our modelling framework, to set up a reservoir model that can be run in either AUTOUGH2 (our version of the well-known simulator TOUGH2) or in Waiwera, our own highly parallelized simulator.

The new digital conceptual model gives an improved representation of the geological formations, the faults and the alteration zone and the corresponding numerical model gives an improved match to most of the data. The new model produces much better results for temperature decline and pressure decline followed by pressure recovery in the deep wells, such as BR59, BR60 and BR61, on the West Bank of the Waikato River.

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.
