Proppant back-production prediction software is also present in this paper, which can determine the critical gas flow rate and critical daily yield for proppant flowing back.

根据上述的基础理论研究，编制了压裂气井生产过程中支撑剂回流预测软件，该软件可预测支撑剂发生回流的临界气流速度和临界气井产量。

Proppant plays a vital role in recovery of sand-producing gas reservoirs. Moreover, relative permeability is one of the most important parameters for performance evaluation of reservoirs.

在出砂气藏，支撑剂对其开采有着至关重要的作用，而相对渗透率又是支撑剂性能评价的重要参数之一。

Short sweeps of clean composite fracturing fluids are applied to mitigate proppant buildup in the near-wellbore area, thus reducing the risk of screenouts and proppant flowback.

小规模多段式注入清洁复合压裂液用于减少支撑剂在近井区域的堆积，从而降低了砂堵和支撑剂返排的风险。

Carbo Ceramics is a leader in making what's called ceramic proppant, which is the synthetic material, sand-based often, with chemicals that are injected into the fractured rock to hold open the cavities so the natural gas goes up into the piping that captures it.
