本研究は、中国で76%を占める枯渇油ガス貯留層型地下ガス貯蔵庫（UGS）の漏洩事故に着目し、その進化メカニズムと予防対策を体系的に分析した。事故統計と専門家インタビューに基づき、地質体、注入生産井、地上設備の3カテゴリーの漏洩要因を同定。さらに、グラウンデッド・セオリーとシステムダイナミクスを用いて、人間・機械・環境・管理の4要素の結合効果が事故進化に影響することを明らかにした。主な漏洩形態は注入生産井（57%）で、地質体（28%）が続く。結果はリスク識別と防止策の理論的基盤を提供する。
English
This study systematically analyzes leakage accidents in depleted oil/gas reservoir underground gas storages, which constitute 76% of China's UGS. Using statistical analysis, grounded theory, and system dynamics, it identifies three leakage types (geological, well, surface facilities) and constructs a human-machine-environment-management (H-M-E-M) evolution model. Injection-production well leakage accounts for 57% of incidents, geological leakage 28%. The research offers theoretical support for risk identification and whole-process prevention measures.

日本のGX文脈において
日本では主にLNG基地を使用しており、枯渇油ガス層型UGSは少ないが、天然ガスの安定供給とエネルギー安全保障の観点から、類似の貯蔵設備（例えば岩盤貯蔵）の安全性評価に応用可能。CCS（CO2貯留）の安全性研究にも示唆を与える。
In the global GX context
While focused on Chinese UGS, the proposed evolution model and risk control framework (H-M-E-M) are globally applicable to natural gas storage safety. As natural gas remains a transition fuel, ensuring storage integrity is critical for energy security and decarbonization pathways. The findings also inform risk management for CO2 storage in depleted reservoirs (CCS).

📄 Abstract（原文）
With the acceleration of the global low-carbon energy transition, the demand for natural gas continues to grow. As core infrastructure for ensuring a stable natural gas supply, the safety issues of underground gas storages (UGS) are becoming increasingly prominent. In China, depleted oil and gas reservoir-type UGS account for 76%, making them the main type in this field. However, frequent leakage accidents pose a serious threat to the safe operation of UGS. This study takes depleted oil and gas reservoir-type UGS as the research object to systematically investigate the evolution mechanism and risk prevention and control of leakage accidents. Firstly, through statistical analysis of accident cases and expert interviews, the main influencing factors of leakage accidents were identified, including three categories: geological body leakage, injection-production well leakage, and surface facility leakage. Secondly, using the Grounded Theory method, the core categories in the driving stage of leakage accident evolution were extracted, and a conceptual model of driving factors for leakage accident evolution based on the four elements of "Human, Machine, Environment, and Management (H-M-E-M)" was constructed. Thirdly, through system dynamics modeling and numerical simulation, the dynamic evolution law of leakage accidents from initial evolution to secondary disasters was revealed. Finally, from the three dimensions of source prevention, process control, and emergency response, precise whole-process prevention and control measures were proposed targeting the four categories of factors: human, equipment, environment, and management. The research indicates that injection-production well leakage is the main form of UGS leakage, accounting for 57%, followed by geological body leakage (28%). The evolution of leakage accidents is influenced by the coupling effect of the four elements: Human, Machine, Environment, and Management. The constructed evolution mechanism model can effectively reflect the structural characteristics of the leakage accident system. The research results provide a theoretical basis and technical support for the precise identification and efficient prevention and control of leakage risks in depleted oil and gas reservoir-type underground gas storages.
