Porous petroleum fracturing propping agent and preparation method thereof

The invention provides a porous petroleum fracturing propping agent and a preparation method thereof, and belongs to the technical field of oil-gas well fracturing in oil exploitation. The porous petroleum fracturing propping agent is prepared from bauxite fine powder, bentonite, manganese powder, silicon carbide fine powder, kyanite fine powder and activated alumina fine powder. Compared with an existing medium-density petroleum fracturing propping agent, the porous petroleum fracturing propping agent has the advantages that particles of the roasted propping agent have more opening pores by adopting silicon carbide as a pore forming agent, more scale inhibitors can be accommodated in the propping agent since the porous structure is capable of providing a space structure to portability of the scale inhibitors, and generation of well scale is prevented or reduced by means of slow release of the scale inhibitors after the propping agent and fracturing fluid are pumped into the well by high pressure. Furthermore, the porous petroleum propping agent has a rather low volume density, and the low-density propping agent can be used for overcoming the defect that the fracturing fluid and the propping agent are blocked to flow deep to the rock crack since a high-density propping agent easily forms moundy accumulation at the port of the rock crack, so that the yield of an oil-gas field can be increased.
