固井作业中,因常规水泥与钻井泥浆难以相容,造成固井水泥污染,严重影响固井质量。设计了密度为1.52～1.60g/cm~3的高炉水淬矿渣固井液体系,该体系以矿渣为水化材料,再加入激活剂。对该体系与两种早强高密度水泥浆的相容性、配伍性进行了对比试验。结果表明,该技术能提高固井质量,降低固井成本。 Cementing operations, because conventional cement and drilling mud is difficult to compatible, resulting in cementing cement pollution, seriously affecting the cementing quality. The cementing fluid system of blast furnace water quenching slag with density of 1.52 ~ 1.60g / cm ~ 3 was designed. The system uses slag as hydration material and then activator. The compatibility and compatibility of the system with two kinds of early strength and high density grouts were compared. The results show that the technology can improve the cementing quality and reduce the cost of cementing.
