根据Ｆｕｒｎａｓ的粒度级配原理，选用空心微珠和硅灰作为减轻剂，配以适当的油井水泥外加剂，配制出的浆体密度为１．２５～１．４５ｇ／ｃｍ３。室内实验评价表明，该低密度水泥浆体系具有良好的综合工程性能，水泥石低温早期强度发展快，３０℃条件下水泥浆凝结４８ｈ...
According to Furnas’s principle of particle size grading, hollow beads and silica fume were selected as mitigating agents. Appropriate oil well cement admixtures were used to prepare slurry density of 1.25-1.45g / cm3. Laboratory experiments show that the low-density cement slurry system has a good overall engineering performance, early strength of cement stone rapid development at 30 ℃ condensate under 48h ...
