Example Embodiment

[0051] Example 1:

[0052] After the block is first prepared silica sand, soda ash, limestone, and feldspar raw materials, the grinding process, and to ensure that material is dried, pulverized and the raw material for processing iron treatment to ensure the quality of raw materials, and then taking 45 parts quartz powder, 35 parts of soda ash powder, limestone powder prepared by mixing 14 parts and 34 parts of feldspar raw batch, the batch in crucible furnaces or kilns 1600 ℃ high-temperature heating, so as to form a uniform, bubble-free, and meet the molding requirements The liquid proppant will be formed by high-temperature machining, by annealing, quenching, etc., cleans or produce stress, phase-phase or crystallization of the proppant, and changing the structural state of the proppant, and will be molded The proppant is pulverized to 70 mesh-140 mesh, and the powder is uniformly put into the special bead furnace by the cloth, and heats melt in a high temperature gas stream of...

Example Embodiment

[0054] Example 2:

[0055] First prepare raw materials such as stone-shaped sand, pure base, limestone, and lear, comminution, and ensure drying of raw materials, and carry out the iron treatment, to ensure the quality of the raw material, then take 40 parts of the stone powder. 32 copies of pure alkali powder, 37 pieces of limestone powder and 11 parts of longite powder, mixed with a mixture of 1550 ° C in the pool kiln or crucible kiln, so that it is uniform, no bubbles, and conforms to form requirements. The liquid proppant will be formed by high-temperature machining, by annealing, quenching, etc., cleans or produce stress, phase-phase or crystallization of the proppant, and changing the structural state of the proppant, and will be molded The proppant is pulverized to 40 mesh-70 mesh, and the powder is uniformly put into the special bead furnace by the fracture, heating in a high temperature gas stream at 1750 ° C, forming a spherical proppant under the surface tension of the...

Abstract

The invention discloses a production principle and process of a special fracturing propping agent with strong anti-pressure ability. The production principle of the fracturing propping agent is as follows: calcium silicate and sodium silicate are prepared through high-temperature composite reaction of silicon dioxide, sodium carbonate and calcium carbonate, and the chemical reaction is carried outin a high-temperature environment; the production process of the fracturing propping agent comprises the following steps of 1, pre-processing raw materials, 2, preparing a batch, 3, melting at high temperature, 4, processing and forming, 5, heat treatment, 6, crushing and distributing, 7, heating and melting, 8, cooling and recycling, and 9, graded collection. According to the production principle and process of the special fracturing propping agent with strong anti-pressure ability, a novel propping agent material can be prepared, the pressure resistance is high, the breakage rate is low, and the fracturing propping agent has the characteristics of good spheronization, good fluidity, electrical insulation, stable chemical properties, high heat resistance, high mechanical strength and thelike.

Description

Technical field [0001] The present invention relates to the technical field of fracturing proppant, and is specifically a characteristic principle and process of a sticker proppant having a strong pressure resistance. Background technique [0002] Fracturing proppant is a ceramic particle product having a high fracturing strength, and can be used to support in the crack generated by the underlying fracturing, so the quality of the fracturing proppant directly affects its life; [0003] However, the current fracturing proppant, when the production is carried out, the cost of production is high, and the pressure resistance capacity of the production is not strong, it is easy to break, which is not conducive to ensuring support of the flow of flow, so we propose Specific principles and processes of a fracturing proppant of a variety of compressive capacity to facilitate solving the problems presented in the above. Inventive content [0004] SUMMARY OF THE INVENTION An object of the...
