Technical Field
The invention relates to the technical field of cement paste, in particular to oil-based rock debris cement paste and a preparation method thereof.
Background
The cement is a powdery hydraulic inorganic cementing material, is made into slurry after being stirred by adding water, can be hardened in the air or better in water, and can firmly bond materials such as sand, stone and the like together. As an important cementing material, the cement is widely applied to the fields of civil construction, water conservancy, national defense and the like. Most of the components in the drilling cuttings are siliceous, calcareous and aluminous materials, and are consistent with the components required by cement production raw materials. If the drilling cuttings are unreasonably treated, the drilling cuttings are accumulated to affect the environment, so that the environmental pollution is increased, the land is occupied, and the resources are wasted. The antibacterial effect is poor in the cement manufacturing process, microorganisms are easy to breed, and the use of subsequent products is influenced.
