Abstract

The invention relates to a high-strength compress supporting agent for coarse oil and a preparation method thereof. The high-strength compress supporting agent for the coarse oil is prepared from the following raw materials by mass portion: 60 to 85 portions of ceramic roller waste, 1 to 20 portions of red mud, 0 to 20 portions of fly ash, 0 to 5 portions of manganese oxide or barium carbonate, 0 to 3 portions of dolomite and 5 to 10 portions of ceramic clay. The ceramic roller waste refers to corner waste or / and damaged and broken ceramic roller waste in the processing process of ceramic roller manufactures, and Al2O3 content of chemical compositions of the ceramic roller waste is not less than 68 percent. The high-strength compress supporting agent for the coarse oil prepared from the ceramic roller waste with high alumina content has the characteristics of high strength and acid resistance, and is used for oil fracturing in medium-deep wells; and the preparation method is simple and feasible, and is suitable for batch production.

Description

technical field [0001] The invention relates to a high-strength petroleum fracturing proppant and a preparation method thereof, belonging to the technical field of new materials. Background technique [0002] Petroleum fracturing proppants are supports that keep rock fractures deep in the formation open. During use, the proppant is mixed into the fracturing fluid, and injected into deep rock fractures by high-pressure means to support the rock formation, so as to improve oil conductivity and increase crude oil production. For medium-deep oil wells, the proppant is required to have high strength and acid resistance to withstand the huge pressure of the rock formation and the environmental corrosion in the formation. [0003] There are already literature and patent reports on oil fracturing proppant. Gao Haili et al., Ceramics, 2006(10): 43-46, using Panzhihua local Ertan bauxite, bauxite raw meal and high-titanium blast furnace slag as the main raw materials, with special a...
