华北油田储气库群由苏桥、京58、文23储气库组成。作为京津冀地区重要的区域性调控气源，华北油田储气库群通过加快扩容达产和新库建设，采气量、调峰能力保持快速增长。去冬今春，储气库群调峰能力、周期采气量在5年内实现了翻番。

储气库群提前规划注采转换工作，在上轮采气未结束时，就启动了新一轮注气准备。技术人员对所有设备进行“全科体检”，制定检维修工作清单，细化单项设备设施检修方案，完成设备设施维护保养、外输管道通球、大型阀门更换、仪表校验安装等工作。

开启注气工作以来，技术人员一库一策，量身定制不同注气工作制度，合理安排注气生产天数，满足调峰需求。目前，苏桥储气库结合现场实际及生产状态特征，实行“停注平压与缓注平压相结合”“间开间注与多库合注相结合”，最大程度发挥单库和单井注气能力，在确保注够气的同时节能降耗。在新一轮注气周期内，储气库群实施“分阶段调配、分区域控制、差异化注采”的注气方式，本轮注气周期计划注气量预计创建库以来新高，为今冬明春调峰保供蓄足“底气”。

The gas storage group of Huabei Oilfield is composed of Suqiao, Jing 58 and Wen 23 gas storage. As an important regional gas source in the Beijing-Tianjin-Hebei region, the gas production and peak-load capacity of Huabei oilfield have maintained a rapid growth by accelerating capacity expansion and new storage construction. Last winter and spring, the peak load capacity and periodic gas production capacity of gas storage groups have doubled in five years.

The injection and production conversion work of gas storage group is planned in advance, and a new round of gas injection preparation is started before the last round of gas production is finished. The technicians carry out "general physical examination" for all the equipment, formulate the inspection and maintenance work list, refine the maintenance plan of individual equipment and facilities, and complete the maintenance of equipment and facilities, the ball passing of external transmission pipes, the replacement of large valves, and the calibration and installation of instruments.

Since the opening of gas injection work, technical personnel have tailored different gas injection work systems, rationally arranged the number of days of gas injection production, and met the demand for peak regulation. At present, Suqiao gas storage combined with the actual site and production characteristics, the implementation of "stop injection flat pressure and slow injection flat pressure" and "open interval injection and multi-reservoir combined injection", to maximize the single storage and single well gas injection capacity, ensuring sufficient gas injection while saving energy and reducing consumption. In the new round of gas injection cycle, the gas storage group implements the gas injection mode of "phased deployment, subregional control, and differentiated injection and production", and the planned injection volume of this round of gas injection cycle is expected to be the highest since the establishment of the reservoir, and the peak regulation and supply of this winter and next spring are stored.
