| 摘 要： | 建立了相对渗透率和毛管压滞后模型，对已有的黑油模型进行了改进，使得相渗和毛管压力在实际的油藏模拟中更加精确地体现出来，并使改进后的模型能有效地反映注气吞吐过程的真实动态。基于改进的黑油模型，对单井注气吞吐全过程的三个阶段：注气阶段、关井平衡阶段、开井采油阶段，油气的饱和度分布规律进行了模拟计算和结果分析，研究结果对实际的水平地层单井吞吐均具有一定的指导意义和作用。

| Abstract: | In this paper, both relative permeability model and capillary pressure hysteresis model were established, and the existing black oil model was also improved, which can reflect more accurately the effect of real reservoir capillary force and relative permeability on numerical simulation. Single well Huff-Puff process includes gas injection, shut-in and producing periods. Based on the improved black oil model, we studied the oil and gas distribution characteristics of each period in the process. The results obtained have important practical meaning for guiding single well Huff-Puff of real horizontal formation. |
