近日，双台子储气库12号井场7口注气井一次性开井成功。其中首次投产的双51-H1井、双51-H2井分别是辽河储气库群第四、第五口大尺寸水平井。
大尺寸水平井主要采用177.8毫米注采管柱，单井日采气能力高达200万立方米，可提高单井日调峰能力1.5至1.8倍。
它们的顺利投产标志着辽河储气库群今冬明春应急采气能力的又一次大幅跃升，为高效完成今冬明春天然气保供任务增添了重要砝码。
此前储气库已有3口大尺寸井，分别是：双6-H2316（2022年8月31日投产）、双6-H1203（2022年9月10日投产）、双6-H4331（2023年5月6日投产）。
以上3口井均参与了采气生产，目前三口大尺寸水平井注气生产保持平稳运行，平均单井日注气量超过140万立方米。
