Using numerical simulation method, the retrogradecondensation saturation variety and the development effect of the single well dry gas injection is studied.
应用数值模拟技术，研究地层中反凝析液饱和度的变化规律和注干气吞吐技术的开发效果。

The gas phase equilibrated with the solid also had retrogradecondensation, which results in three phases of gas-liquid-solid and layering in the liquid phase.
等液量线与相包络线平行，在一定的温度压力条件下有固相出现。

Removal of the near-wellbore plug and gas lock resulted from retrogradecondensation is a key problem to be tackled during the recovery of deep-buried, low-permeable condensate gas reservoirs.
