摘要: 气藏型储气库是国家能源战略部署重点,承担着天然气调峰保供的艰巨任务。圈闭密闭性是保障储气库安全运行的首要前提,但目前针对气藏型储气库圈闭密闭性的评价方法差异较大,尚未建立系统、完整的评价模式。在国内外大量储气库密闭性评价与监测研究的基础上,基于黄草峡储气库圈闭特点,从盖层密闭性与断层密闭性两方面出发,建立了“静态+动态”结合的气藏型储气库圈闭密闭性评价模式,形成了“监测井+微地震”协同监测方法,并根据监测数据及时动态调整储气库工作参数。通过构建的评价及监测模式,对黄草峡储气库圈闭密闭性进行了初步评价与监测部署,认为其圈闭密闭性良好,研究成果对于完善国内外各气藏型储气库密闭性评价与监测体系具有一定参考价值。

Abstract: The gas reservoir-type gas storage is the focus of the national energy strategy deployment, which undertakes the arduous task of natural gas peak shaving and supply guarantee. Trap tightness is the primary prerequisite to ensure the safe operation of gas storage. However, the evaluation methods for trap tightness of gas reservoir-type gas storage are quite different, and a systematic and complete evaluation model has not been established. On the basis of a large number of domestic and foreign gas storage tightness evaluation and monitoring research, based on the characteristics of Huangcaoxia gas storage traps, a “static-dynamic” combination of gas storage reservoir trap tightness evaluation model was established, focusing on both caprock sealing and fault sealing. Also, a “monitoring well and microseismic” monitoring method was formed, and the working parameters of the gas storage can be dynamically adjusted in a timely manner based on the monitoring data. Through the constructed evaluation and monitoring model, the trap tightness of Huangcaoxia gas storage is preliminarily evaluated and monitored, and it is considered that the trap tightness is good. The research results have certain reference value for improving the evaluation and monitoring system of gas reservoir-type gas storage tightness at home and abroad.

Key words: gas storage reservoir, trap sealing evaluation, static-dynamic combination, collaborative monitoring
