Embodiment 1
[0036]The strengthening protective agent formula of the present invention: 40% of alumina powder, 40% of kaolin, 5% of talcum powder, 10% of clay, 4% of alkaline solvent material, and 1% of auxiliary material.
[0037] The alkaline solvent material in the present invention is a mixture of albite, potassium feldspar, calcium carbonate and magnesium carbonate; the auxiliary material in the present invention is cellulose.
[0038] The present invention also provides a method for preparing the above-mentioned bird's nest proppant, the preparation steps comprising:
[0039] (1) Mud formula: weigh each raw material according to the formula ratio;
[0040] (2) Mixing: Put the powder formed by mixing the raw materials in step (1) into a kneader or a mixer, add water (15% of the weight of the powder) and oil (such as waste oil and rapeseed oil, which can be used as a powder) 5% of material weight) carry out mud kneading, obtain the evenly mixed mud;
[0041] (3) extruding the process...
Embodiment 2
[0044] The raw materials for the preparation of hydrogenation protective agent: 30% of alumina powder, 40% of kaolin, 10% of talcum powder, 15% of clay, 3% of alkaline solvent material, and 2% of auxiliary materials. The preparation steps are the same as in Example 1.
Embodiment 3
[0046] The raw materials for the preparation of the hydrogenation protecting agent mainly include: 50% of alumina powder, 30% of kaolin, 5% of talcum powder, 10% of clay, 4% of alkaline solvent material and 1% of auxiliary material. The preparation steps are the same as in Example 1.
[0047] Table 1 Performance and specifications of the sample of the embodiment of the present invention
[0048]
[0049] Note: The radial crushing strength in the above table 1 is a hydrogenated protective agent with a certain diameter and height, and the length is the strength that can be withstood by the pressure applied at both ends of the axial direction.
[0050] It can be seen from the above examples that the product of the present invention will have more and denser through holes in its unit cross-sectional area, which can greatly increase the external specific surface area of the product, reaching 5000m 2 / m 3 Above, make the reaction raw material and protective agent have larger ...
