Proppant is a key material for fracturing construction. Proppant is brought into and supported in the cracks of the fracturing formation by the fracturing fluid, thereby effectively introducing oil and gas into the oil and gas well, greatly increasing oil and gas production and extending the life of the oil well. Fracture conductivity is one of the important factors affecting the success of acid fracturing. Fracture conductivity is determined by the surface shape of the acid-etched fracture, that is, the spatial distribution characteristics and depth of the acid-etched concave and convex surface.

When conducting proppant and acid-etching simulation experiments, the existing integrated simulation kettle has a relatively complex structural design and is difficult to use. It is inconvenient to adjust the simulation delivery angle and the use temperature of the simulation material in the proppant and acid-etching simulation laboratory, and it is inconvenient to compare multiple simulation methods. It has certain limitations. Therefore, the utility model proposes a proppant diversion and acid-etching diversion integrated simulation kettle device.
