Cement mineral admixture based on water-based drilling cuttings and preparation method thereof
The invention discloses a cement mineral admixture based on water-based drilling cuttings and a preparation method of the cement mineral admixture, and relates to the technical field of cement additive.The preparation method of the cement mineral admixture comprises the following steps that the water-based drilling cuttings in a shaft are selected and fully mixed to be uniform, and after drying, the water-based drilling cuttings are ground into fine particles through a stirring type pulverizer; adding glass slag into the obtained fine particles, uniformly mixing, calcining in a muffle furnace, grinding and ball-milling the calcined product in a ball mill for 40 minutes by taking four steel balls with different masses as media, and collecting a sieved product when the mass fraction of sieve residues of a 45-micron square hole sieve is less than 5.0% as the cement mineral admixture; the preparation method of the cement admixture is simple and easy to implement, the cost is low, and recycling and high-value utilization of industrial solid waste such as the water-based drilling cuttings can be achieved.
本发明公开了一种基于水基钻屑的水泥矿物外加剂及其制备方法，涉及水泥添加剂技术领域，该水泥矿物外加剂制备方法包括以下步骤，选取井筒中的水基钻屑充分混合至均匀，干燥后采用搅拌式粉碎机将水基钻屑磨碎至细小颗粒，将玻璃渣加入得到的细小颗粒中混合均匀，之后置于马弗炉中煅烧，将所得煅烧后产物于球磨机中以四个不同质量钢球为介质研磨球磨40min，收集45μm方孔筛筛余质量分数小于5.0％时的过筛产品作为所述水泥矿物外加剂；本发明中的水泥外加剂制备方法简单易行、成本低廉，且能实现对水基钻屑这类工业固废的资源化和高值化利用。
