摘　　要：为了解决降低固井作业对煤层伤害程度与提高固井质量的矛盾，通过合理匹配漂珠及增强剂等添加剂的比例，优选出一套高强度低密度的漂珠水泥浆配方。室内与现场实验表明，该水泥浆体系稳定，添加剂配伍性好，流动性能好，密度可调范围大，强度能达到API标准要求。漂珠水泥浆应用于煤层气井有利于保护煤层，满足施工需要。To optimize a slurry prescription of high-strength and low-density, we have made rational proportion of ball spill and early strength additive. The tests in the laboratory and field show that this slurry has following featurs such as stable system, good compatibility of additive, good property of flowing and wideadjustable scope about the density. The strength can be up to the standard request of API.
