建立了能够模拟支撑剂粒径分布的裂缝流体力学和原位动力学模型。我们在几个案例中证明，在水力压裂数值模拟中，与用一个有效平均直径表示支撑剂的建模方法相比，考虑颗粒尺寸分布会导致预测裂缝几何形状和导流能力的显著差异。
We introduced fracture hydrodynamics and in-situ kinetics model capable of simulating particle size distribution of propping agent. We demonstrated on several cases that accounting for particle size distribution in numerical simulation of hydraulic fracturing results in a noticeable difference of predicted fracture geometry and conductivity, as compared to the modeling approach where propping agent is represented by one effective mean diameter.
