Description

technical field [0001] The invention relates to a petroleum proppant and a preparation method thereof. Background technique [0002] Petroleum proppant is also called petroleum fracturing proppant. During oil and gas deep well mining, high closure pressure and low permeability deposits are treated by fracturing to crack the oil-gas-bearing rock formations, and oil and gas are collected from the channels formed by the fractures. At this time, fluids need to be injected into the rock base to overcome formation fractures Intensive pressure creates cracks in the rock formations around the wellbore, forming a channel with high-level flow capability. In order to keep the cracks formed after fracturing open, oil and gas products can pass through smoothly. [0003] At present, most of the domestically produced proppants are made of bauxite as the main raw material. These products have low strength, poor corrosion resistance and fracture resistance. Therefore, it is necessary to imp...
