摘要
近年来,国外固井水泥浆体系发展很快,并逐步形成了系列化的产品。介绍了LiteCRETE低密度水泥浆、LiteCRETECBM煤层气固井水泥浆、DensCRETE高密度水泥浆、DeepCRETE深水水泥浆、寒地LiteCRETE水泥浆及SqueezeCRETE挤水泥用水泥浆几种不同的水泥浆体系及其应用情况。上述水泥浆体系较好地解决了提高低压易漏长封固段固井、易受伤害低压煤层气井固井、高压油气井固井、深水低温井固井、寒地低温井固井及补救挤水泥的成功率的问题,对提高中国复杂井的固井成功率及下一步开展有针对性的固井技术研究工作具有较好的借鉴意义。
The overseas cement slurry systems have been booming in recent years and series of slurry additives have been developed. This paper discusses the several cement slurries such as LiteCRETE low density slurry, LiteCRETE CBM slurry for use in coal bed gas zone cementing, DensCRETE high density slurry, DeepCRETE slurry for use in deep water, LiteCRETE slurry for use in cold area and Squeeze CRETE, and the application thereof. Some cementing problems, such as low-pressure long intervals in which mud losses are f...
