【摘要】 油井水泥的性能直接关系到水泥浆性能的稳定和油气井的生产寿命。因此,世界各国对油井水泥的质量标准都作了严格的规定。以G级水泥为例阐述了油井水泥质量检测的标准,讨论了水泥化学组成、熟料矿物组成及物理性能对水泥浆工程性能的影响。通过对14种国产G级中抗硫酸盐油井水泥质量检测指标的分析,并针对国内油田在这方面存在的问题,提出了相应的建议。更多还原

【Abstract】 As the property of oil well cement influences the stabilization of cement slurry and production life of oil gas wells directly, strict regulations are made on the quality standards internationally. The paper tries to explain the standards with Grade G cement as an example, and discusses the influence of chemical and mineral composition and physical characteristics on cement slurry performance. The author listed some problems exist in inspection and field operation with some advice given.更多还原
