气藏型储气库群周期动态监测系统的建立与应用

Establishment and application of periodic dynamic monitoring system for gas storage group of gas reservoir type

动态监测是储气库群运行中的一项重要工作,贯穿于储气库群生产运行始终。为了保障地下储气库群安全、高效、科学合理的运行,大港油田气藏型X储气库群建立了以压力场监测、流体场监测、注采井生产能力监测及流体组分监测为主要内容的监测系统,实现了对储气库群全方位、立体化监测,为储气库群的运行管理、安全评价、动态分析提供了科学依据。通过该储气库群周期动态监测系统的建立和应用,不仅实现了X储气库群多周期的安全平稳生产,同时结合各个储气库实际注采特点、动用状况,指导X储气库群下步“扩容达产”方案的调整和优化,保证其安全高效、科学合理运行。

Dynamic monitoring is an important task that runs through the production and operation of the gas storage group.To ensure the safe,efficient,scientific and reasonable operation of underground gas storage group,a monitoring system mainly for pressure field,fluid field,production capacity of injection and production wells and fluid composition was established by Dagang Oilfield X gas storage group of gas reservoir type.It has realized all-round and three dimensional monitoring of gas storage group and provided scientific basis for the operation,management,safety evaluation and dynamic analysis of gas storage group.The establishment and application of the monitoring system not only realized the multi-period safe and stable production of X gas storage group,but also guided the adjustment and optimization of the later expansion and production plan of X gas storage group by combining the actual injection and production characteristics and production conditions of each gas storage,which ensured safe,efficient,scientific and reasonable operation.
