摘要： Storable compositions and slurries for cementing oil and gas wells are described which comprise blast-furnace slag besides other additives which are usual in the cementing technique. The compositions and slurries are insufficiently activated (or are activated immediately before introducing them into the well), so that they can be stored for at least 72 hours (alternatively they may be stored indefinitely) without the setting of the composition and dispense with the addition of activation inhibitors. The use of the compositions and slurries in the cementing of oil and gas wells is also described.

摘要翻译： 描述了用于固井油气井的可储存组合物和浆料，其除了在固井技术中通常的其它添加剂之外还包括高炉渣。 组合物和浆料活性不足（或者在将它们引入孔之前立即被活化），使得它们可以储存至少72小时（或者它们可以无限期地储存），而不需要组合物的配置，并省去添加剂 的活化抑制剂。 还描述了在油气井的固井中使用组合物和浆料。
