Abstract

The invention discloses a fracturing propping agent additive, a fracturing propping agent and a preparation method of the fracturing propping agent. The fracturing propping agent additive comprises the following raw materials in parts by weight: 5-13.5 parts of borax, 11.5-23.7 parts of silicic acid, 8.7-15 parts of molybdic acid, 55.2-67 parts of bentonite, 10-16.3 parts of coal ash and 5-9.8 parts of aluminum carbonate; and the fracturing propping agent comprises the following raw materials in parts by weight: 35-48 parts of 30-45% bauxite, 2-5 parts of the fracturing propping agent additive, 2-10 parts of molybdenum oxide, 3-8 parts of lanthanum oxide, 5-13 parts of magnesium sulfate and 50-62 parts of clay. The fracturing propping agent has the advantages of low volume density, apparent density, acid solubility and crashing rate, the cost is reduced, the fracturing propping agent is convenient to carry and is more beneficial to fracturing stimulation, a product is high in cost performance, the production method is simple, and the fracturing propping agent is good in use effect.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a fracturing proppant additive, a fracturing proppant and a preparation method. Background technique [0002] Fracturing proppant is a ceramic particle product with high fracturing strength. It is mainly used for downhole support in oil fields to increase oil and gas production. It is an environmentally friendly product. This product is made of high-quality bauxite and other raw materials, and is sintered with ceramics. It is a substitute for medium and low-strength proppants such as natural quartz sand, glass balls, and metal balls. It has a good effect on increasing oil and gas production. 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 gather from the channels formed by the fractures. The ceramsite support material is used to enter the for...
