摘要

在这项工作中，基于随机梯度方法的数值优化技术被用来帮助地热运营商找到更好的油田开发战略，这些战略对已考虑的地质不确定性具有稳健性。通过优化油井类型、生产率目标和油井位置，在叠层储层的实际案例中实现了低焓热回收的经济效益最大化。与工程师设计的策略相比，效果显著提高。施加断层稳定性约束会对优化配置产生重大影响，协调井率和井位对提高地热生产效率起着关键作用，同时将应力变化影响控制在可接受的范围内。

Geothermal field development optimization under geomechanical constraints and geological uncertainty: Application to a reservoir with stacked formations

In this work, numerical optimization based on stochastic gradient methods is used to assist geothermal operators in finding improved field development strategies that are robust to accounted geological uncertainties. Well types, production rate targets and well locations are optimized to maximize the economics of low-enthalpy heat recovery in a real-life case with stacked reservoir formations. Significant improvements are obtained with respect to the strategy designed by engineers. Imposing fault stability constraints impacts significantly the optimal configurations, with coordinated well rates and placement playing a key role to boost efficiency of geothermal production while keeping stress change effects to acceptable limits.

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.
