Embodiment

[0046] First, crush quartz sand, soda ash, limestone, feldspar and other raw materials, and then wash and separate them to remove impurities. After standing in water for 3 hours, take them out and dry them to a dry state. At the same time, remove iron from the dried raw material powder. , to ensure the quality of raw materials, the ratio of quartz sand: soda ash: limestone: feldspar = 1: 0.8: 0.95: 0.45 is used to mix the raw materials, and prepare them as batch materials for later use. Heating at ℃ to form a liquid proppant that is uniform, free of bubbles, and meets the molding requirements, and then the liquid proppant is molded, and the molding process is granulated by a granulator, and then the molded proppant is annealed and quenched. The fracturing proppant is heat-treated to clean or generate stress, phase separation or crystallization inside the proppant, and change the structural state of the proppant to ensure the strength of the proppant, and the heat-treated proppa...

Abstract

The invention discloses a production method of a high-strength non-adhesive fracturing propping agent. The production method of the fracturing propping agent comprises the following steps of 1, crushing and processing raw materials, 2, mixing the raw materials to prepare a mixture, 3, melting the mixture, 4, molding and granulating, 5, heat treatment, 6, crushing and grading, 7, heating and melting, 8, bead collecting treatment, and 9, grading and packaging. According to the production method of the high-strength non-adhesive fracturing propping agent, the quality of raw materials can be guaranteed, meanwhile, crushing treatment on the propping agent is guaranteed, beads are collected in time after heating melting is conducted, propping agent adhesion is avoided, the propping agent is ensured to be high in strength and non-adhesive, meanwhile, the balling property and flowability are good, and it is guaranteed that the chemical property is stable and heat resistance is stable; the mechanical strength is high, and the stable propping and flow guiding effects can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of fracturing proppants, in particular to a production method of a high-strength and non-adhesive fracturing proppant. Background technique [0002] Fracturing proppant has the advantages of high compressive strength, low density, good sphericity, etc., and has high fracturing strength. It is mainly used for downhole support in oil fields to increase oil and gas production, and can ensure high conductivity. It is unobstructed oil and gas, increasing production; [0003] However, when the current fracturing proppant is produced, the production of the proppant will cause the proppant to stick to each other, which is not conducive to ensuring the fluidity of the proppant, and at the same time it cannot have a good flow diversion and strength. Therefore, we propose a A method of producing a high strength non-stick fracturing proppant in order to solve the problems posed above. Contents of the invention [00...
