The researches of the proppant transportation and settling in the fracture are important for the fracturing treatment design and the productivity calculation of the fractured well. Euler-Euler two-phase flow model was established to numerically simulate the transportation and settling in the 3 D hydraulic fracture with the help of Fluent Software. The turbulent effect and the particle-particle interaction were considered in the model for the fracturing liquid. By means of the model,the influences of the dif...
