中新网大庆8月8日电 (王立峰)8日,记者从大庆油田了解到,截至当日,大庆油田杏南开发区已累计实施不停机间抽653口井,年节电339.05万千瓦时,实施井平均系统效率较连续生产提高5.14个百分点,平均泵效提高8.6个百分点。曾经“连轴转”的一批低产井,如今在“抽抽停停”的智慧调度中,跑出提质增效加速度。

杏南油田开发进入中后期,低产井供液不足矛盾凸显。传统连续抽油模式普遍存在空抽、液击现象,往往供液不足,泵效低下,设备空抽磨损严重,检泵周期大幅缩短,能耗浪费突出。
间抽,全称间歇抽油,即针对能量不足的油井,合理启动和关闭抽油设备,利用井筒储存效应使液面恢复,再开井生产。这既能减少运行时间和电能消耗,又能提高泵效,避免“干抽”带来的设备损耗,延长检泵周期。但传统人工间抽靠人现场拉闸启停,成本高、精度低;自动间抽虽能定时操作,却无法根据油井实时状态灵活调整。
2022年初,采油五厂工艺研究所的技术人员在杏南开发区开始进行间抽技术攻关,建立产量可控的动态寻优方法,以产液量波动小于5%为底线,通过优化动液面恢复曲线,自动算出每口井的最佳启停时机。
多井实测数据表明,间抽在产液量基本稳定的前提下,节能效果相当可观。实施井平均单井日节电38.9千瓦时,年累计节电339.05万千瓦时。运行时间减少使得杆管磨损也大幅降低,平均单井检泵周期延长25天。(完)
