摘要:
目前常规可溶复合桥塞已经成为分段压裂施工中临时封堵层段的有效工具,坐封后受井内温度和矿化度的影响,其封堵时间不超过24小时。为满足特殊井况的作业需求,研制一种新型可溶解桥塞,这种桥塞坐封后可应对长时间的修井作业施工,不会因温度和矿化度影响而失封,作业结束后可根据需要通过注液快速溶解,达到畅通井筒的目的。现场应用完全达到预期效果。
Abstract:
Currently,the conventional dissolvable composite bridge plug has become an effective tool for temporarily plugging intervals in the staged fracturing construction. After setting,affected by the temperature and salinity in the well,the plugging seal time does not exceed 24 hours. In order to meet the operation requirements of special well conditions,a new type of dissolvable bridge plug was developed. After the bridge plug is set,it can cope with long-term workover operations without losing its seal due to the influence of temperature and salinity. After the operation is completed,the bridge plug can be quickly dissolved by special chemical liquid injection as needed to achieve the purpose of unblocking the wellbore. This new generation dissolvable bridge plug has been successfully used in multi-well operations.
