Abstract
Proppant flowback is one of the key issues in the fracturing fluid rejection process. It is generally believed that the fracturing fluid rejection flow rate has an important influence on the stability of the proppant particle stack, and some studies have clarified the critical flow rate for fracturing fluid rejection. In this paper, the existing computational models of critical rejection flow rate for proppant rejection flow rate are validated through CFD-DEM simulation. The effect of parameters (particle size and density) of proppant particle and secondary crack on critical rejection flow rate is studied and the corresponding flow mechanisms are revealed. The results of the study can provide theoretical guidance for optimizing the fracturing fluid rejection process.
