摘要
在“双碳”目标驱动下,天然气站场热工暖通系统的高能耗与碳排放问题已成为制约油气田地面工程绿色化转型的重要挑战。作为化石能源向清洁能源过渡的“战略支点”,天然气站场需在保障能源安全供给基础上,实现低碳化技术升级与系统性管理重构。当前天然气站场热工暖通系统设计存在三大问题:负荷预测模型与真实场景偏差大、设备能效冗余导致运行成本增加、全生命周期管理体系缺失引发隐性碳足迹积累。为了解决上述矛盾,创造性构建动态建模-多能协同-全周期管理三位一体优化框架。通过Openstudio与实测数据融合Sketchup建模,构建站场动态热负荷预测模型,精准解析不同功能区的时空能耗特征;开发多能互补技术,集成地源热泵、光伏直驱空调及相变储热等核心技术,实现天然气站场热工暖通系统与新能源技术的深度融合;建立覆盖设计-运维-退役的全生命周期管理体系,依托数字孪生平台实现碳排放动态追踪与能效闭环优化。该优化框架可显著提升系统综合能效与余热利用率,降低热工暖通系统碳排放强度,同时,深化数字孪生技术与全生命周期碳管理体系的融合应用,推动站场从单一能源输配节点向多能协同的低碳枢纽转型,为天然气站场绿色化改造提供理论支撑与实践示范。
Driven by the goal of"double carbon",the high energy consumption and carbon emission of natural gas station thermal and HVAC systems has become an important challenge that restricts the green transformation of oil and gas field ground engineering.As a"strategic pivot"for the transition from fossil energy to clean energy,natural gas stations need to realize low-carbon technology upgrading and systematic management restructuring on the basis of guaranteeing safe energy supply.Currently,there are three major problems in the design of natural gas station thermal HVAC systems:large deviations between load prediction models and real scenarios,increased operating costs due to redundant energy efficiency of equipment,and accumulation of hidden carbon footprints due to the lack of a full life-cycle management system.In order to solve the above conflicts,a three-in-one optimization framework is creatively constructed of dynamic modeling,multi-energy synergy,and full-life cycle management.Through Openstudio and Sketchup modeling of measured data,a dynamic heat load prediction model is constructed for the station,which accurately analyzes the spatial and temporal energy consumption characteristics of different functional areas.A multi-energy complementary technology is developed,which integrates the core technologies of ground-source heat pumps,photovoltaic direct-drive air conditioners,and phase-change thermal energy storage to realize the in-depth fusion of the thermal HVAC system of the natural gas station with new energy technologies.A full-life cycle management system covering the design-operation and maintenance-retirement period is established,relying on the digital twin platform to realize dynamic tracking of carbon emissions and closed-loop optimization of energy efficiency.The optimization framework can significantly improve the comprehensive energy efficiency and waste heat utilization rate of the system,reduce the carbon emission intensity of the thermal HVAC system,at the same time,deepen the integration and application of the digital twin technology and the full-life cycle carbon management system,promote the transformation of the station from a single energy transmission and distribution node to a multi-energy synergistic low-carbon hub,and provide theoretical support and practical demonstration for the greening transformation of the natural gas station.
