枯竭油气藏型地下储气库事故分析及风险识别
Accident analysis and risk identification of underground gas storage rebuilt upon the depleted oil and gas reser-voirs
摘要
Abstract
According to the statistics, there are 478 underground gas storages rebuilt upon the depleted oil and gas reser-voirs, the number of which accounts for about 76.2% of the total gas storages in the world, so there exists many complex risk factors threatening the safety of this type gas storage. Based on the statistical analysis of the previous accidents at this type gas storage, and by use of the risk evaluation method of gas pipeline, three types of accidents are classified by the damage on the casings or injection and production wells, gas migration in the gas injection process, and the failure on ground facilities, and the potential risk factors in the storage system are preliminarily divided into 12 categories and 33 sub-types. According to the rela-tionship between the risk factor and the time, risk is divided into three kinds: time-dependent, constant and random emer-gence. The fault tree analysis was adopted to investigate and identify the main risk factors that lead to the main accidents, and then the corresponding risk assessment procedure was put forward. This study provides a theoretical basis for the formulation of risk-prevention countermeasures and safety management decision-making on the underground gas storages rebuilt on the de-pleted oil and gas reservoirs.关键词
