Oil-based rock debris cement paste and preparation method thereof

Abstract

The invention discloses oil-based rock debris cement paste which comprises the following raw materials in parts by weight: 90-100 parts of cement, 10-15 parts of oil-based rock debris, 30-40 parts of metal powder, 1-3 parts of an anti-freezing agent, 1-3 parts of an antibacterial agent, 1-3 parts of a defoaming agent, 15-35 parts of gypsum powder and 30-35 parts of water. The preparation method of the oil-based rock debris cement slurry comprises the following steps: weighing the raw materials, crushing and sieving the raw materials, uniformly mixing the raw materials, calcining and cooling the raw materials, and stirring the raw materials to prepare slurry. The main component of the oil-based rock debris subjected to thermal desorption treatment is a siliceous material, so that the cement component is reduced, the cost is reduced, and the waste utilization rate is high; wherein the metal powder are slags, so that the compression resistance of the cement is enhanced; due to the anti-freezing agent, the cement paste is good in use state under the low-temperature condition; moreover, the antibacterial agent endows the cement with a good antibacterial effect, wherein the nano titanium dioxide has a photocatalytic function, can generate hydroxyl radicals with high oxidability in water after absorbing light, and plays a role in sterilization.

Description

technical field [0001] The invention relates to the technical field of cement slurry, in particular to an oil-based cuttings cement slurry and a preparation method thereof. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. It becomes a slurry after being stirred with water. It can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. As an important cementing material, cement is widely used in civil engineering, water conservancy, national defense and other fields. Most of the components in drilling cuttings are siliceous, calcareous, and aluminum materials, which are consistent with the ingredients required for cement production. However, if the drilling debris is not properly disposed of, it will have an impact on the environment after accumulation, increase environmental pollution, occupy land, and waste resources. In the process of cement production, the antibacterial effe...

Problems solved by technology

However, if the drilling debris is not properly disposed of, it will affect the environment after accumulation, increase environmental pollution, occupy land, and waste resources.

In the process of cement production, the antibacterial effect is poor, and it is easy to breed microorganisms, which affects the use of subsequent products
