机械式μμ犚水泥承留器在储气库老井封堵中的应用

摘要

为保证储气库气密封的完整性，在国内油气藏型储气库建设中，将区块内的老井全部封堵。通过对老井井况和封堵工艺分析，制定合理可行的封堵措施，优选成熟的封堵工艺，应用先进的井下工具，确保了储气库老井封堵施工质量符合储气库老井封堵要求。在储气库老井封堵施工中，机械式MMR水泥承留器的成功应用进一步提高了老井封堵作业效率，并为老井封堵积累了丰富经验。%On the underground gas storage about the depleted oil and gas reservoirs in China,oil and gas well was plugged in order to ensure the integrity of gas storage.By analyzing old well and plugging technology,a practical scheme,optimal mature technology,the use of advanced tools were worked out to ensure that plugging quality meets the gas storage requirements.Applications for cement retainer squeezing,the efficiency of the plugging would have been increased,and we have accumulated rich experience for old well plugging.
