Development and Application of Additive in Deepwater Cementing

  • 摘要: 针对深水固井面临的低温、海底松软地层、浅层流等技术难题,采用单体复配技术开发了新型深水固井低温早强剂PC-DA92S、PC-DA93L,采用悬浮聚合技术开发了低温降滤失剂PC-DG72S。根据南海海域钻探的实际井况,研制出了适合现场应用的2种低温水泥浆,对该水泥浆在深水环境下的性能进行了评价。在南海LH16-1-1井的现场应用结果表明,2种低温水泥浆体系低温早强效果良好,具有失水量小、防气窜能力良好、稠化时间易于调整、水泥浆性能稳定等优点,能够满足现场施工要求,可用于海洋深水表层套管固井。
    Abstract: According to the technical challenges in deepwater well cementing,such as low temperature,soft seabed,shallow water flow,and etc.,new types of deepwater cementing additive PC-DA92S,PC-DA93L and PC-DG72S with monomer complex technical have been developed.According to the actual well conditions in South China Sea,suitable cement slurry system for field application has been developed.Properties of this cement slurry system under deep water has been analyzed and evaluated.After being applied in Well LH16-1-1 in the South China Sea,it showed that the two cement slurry systems were characterized by early strength at low temperature,low fluid loss,good anti-gas channeling ability,ease in adjusting the thickening time,stable cement slurry system,and etc..So,it can be used for deepwater cementing of surface casing.
