在完整的论文中,介绍了深层闭环地热系统(DCLGS)作为传统增强型地热系统(EGS)的替代方案,用于全球可扩展和可调度的绿色能源生产。作者证明,DCLGS 井的发电规模可以与 EGS 相当。他们还强调了经济地钻探 DCLGS 井仍然存在的技术差距和需求,并写道,可以扩展大位移钻井 (ERD) 和高压/高温 (HP) 方面的石油和天然气技术、专业知识和经验。 /HT)钻探以建造复杂的 DCLGS 井。

介绍

CLGS 被认为是 EGS 的子集,但作者写道,它是一个独特的实体。EGS 主要涉及依赖裂缝排热的井设计。此类系统与 CLGS 井的不同之处在于后者使用封闭管道进行热流体循环和加热。

In the complete paper, deep closed-loop geothermal systems (DCLGS) are introduced as an alternative to traditional enhanced geothermal systems (EGS) for green energy production that is globally scalable and dispatchable. The authors demonstrate that DCLGS wells can generate power on a scale comparable to that of EGS. They also highlight technology gaps and needs that still exist for economically drilling DCLGS wells, writing that it is possible to extend oil and gas technology, expertise, and experience in extended-reach drilling (ERD) and high-pressure/high-temperature (HP/HT) drilling to construct complex DCLGS wells.

Introduction

CLGS is considered a subset of EGS, but the authors write that it is a distinct entity. EGS mostly involves well designs that rely on fractures for heat extraction. Such systems are different from CLGS wells in that the latter use closed conduits for thermal fluid circulation and heating.
