Problems solved by technology

On the other hand, currently the production of petroleum proppants generally adopts relatively expensive pyrolusite powder (the main chemical composition is MnO 2 ) as a mineralizer has the advantages of strong mineralization effect and good effect, but the disadvantage is that it is more expensive and has a very low melting point (390°C). Therefore, when there are many impurities with low melting point in the raw material, it is easy to cause the oil proppant to be damaged. The firing range becomes narrower, agglomerates appear, and even stick to the kiln and form rings

Abstract

The invention belongs to the technical field of petroleum propping agents, and particularly relates to a petroleum fracturing propping agent and a preparation method thereof. The petroleum fracturingpropping agent is prepared from bauxite powder, crushed fine powder, calcium aluminate cement and polysiloxane. The petroleum fracturing propping agent with excellent breaking rate performance is successfully prepared by taking a secondary bauxite powder as a raw material instead of taking the primary bauxite or the special bauxite as the raw material through optimization of product raw materialsand a preparation process.

Description

technical field [0001] The invention belongs to the technical field of petroleum proppant, and in particular relates to a petroleum fracturing proppant and a preparation method thereof. Background technique [0002] With the development of natural gas and petroleum industries, hydraulic fracturing technology has been widely used in the exploitation of oil and gas fields. During the implementation of hydraulic fracturing technology, petroleum proppant is a key factor affecting the implementation effect. The role of petroleum proppant is to support the two walls of rock fractures in hydraulic fracturing, ensuring that when the bottom hole pressure drops below the closing pressure, the fractures leading to the oil and gas wellbore remain open, reducing the flow resistance of oil and gas, thereby To achieve the effect of increasing oil and gas production. [0003] In the past period of time, domestic enterprises mainly used first-grade or even super-grade bauxite, which has le...
