CHERT: Intelligent Thermal Energy Harvesting and Storage for Deep Drilling Operations

无论是石油和天然气开采，还是新兴的地热能源市场，深层钻探作业都是全球能源供应的重要组成部分。现代作业依靠井下深处的复杂传感器和设备来评估油井状况和周围地质情况，但这些都需要可靠的电源。很少有技术可以忍受极端的井下环境，工业目前仅限于危险和间歇性的选择，如氯化亚硫酸锂电池或泥浆涡轮机。电力供应限制严重限制了对油井的监控，并阻碍了地面运营商有效应对问题的能力，后果从生产时间损失到具有不可估量的财务和环境影响的重大灾难。总部位于南威尔士的获奖中小企业Nomein正寻求通过CHERT(联合恶劣环境可再生技术)来彻底改变井下电力和数据，CHERT(联合恶劣环境可再生技术)是一种创新系统，将能量收集、能量存储和先进的传感系统结合在一起，为运营商提供一致的不间断电源和数据，专为井下环境而构建，以减少环境影响和成本，同时提高安全和能源效率。

Deep drilling operations are an essential part of the global energy supply, whether for oil and gas extraction or for the emerging geothermal energy market. Modern operations rely on complex sensors and equipment deep in the well ("downhole") to evaluate the condition of the well and surrounding geology, but these need a reliable power source. Few technologies can tolerate the extreme downhole environment, with industry currently limited to hazardous and intermittent options such as lithium thionyl chloride batteries or mud turbines. Power supply constraints severely limit monitoring of the well and hamper the ability of on-surface operators to respond to problems effectively, with consequences ranging from lost production time to major disasters with incalculable financial and environmental impacts.Nemein, an award-winning SME based in South Wales, are seeking to revolutionise downhole power and data through CHERT (Combined Harsh Environment Renewable Technology), an innovative system that combines energy harvesting, energy storage and an advanced sensing system to provide operators with a consistent uninterruptible power supply and data, purpose-built for the downhole environment to reduce environmental impact and cost whilst improving safety and energy efficiency.
