摘要
伴随油气勘探逐步向深部地层拓展,非常规井、复杂地质情况迅速增加,对作业中固井技术提出了更高的要求。隔离液作为固井作业中的重要一环,影响着油气井寿命和长期生产安全。通过梳理近些年国内外隔离液类型、外加剂选择、性能要求、评价方法研究进展,为隔离液后续进一步研发升级提供了思路,同时也对固井隔离液的发展远景提出了建议。
With the gradual expansion of oil and gas exploration to deep strata,unconventional wells and complex geological conditions are increasing,which puts forward higher requirements for cementing technology.As an important part of cementing operations,spacer fluid affects the life of oil and gas wells and long-term production safety.In this paper,the research progress of domestic and foreign spacer fluid types,additive selection,performance requirements and evaluation methods in recent years was reviewed,which can provide ideas for further development and upgrading of spacer fluids,and suggestions for the development prospects of cementing spacer fluids were also puts forward.
