| 摘 要： | 利用微观可视化渗流实验对凝析气藏衰竭开发过程的反凝析过程中气-液-固复杂流动的渗流规律进行研究,通过高温、高压条件仿真微观可视化模型模拟地层凝析气-液-固流动,直接观测凝析气、液、固(蜡)相的渗流特征和运移机理. 给出蜡沉积吸附和运移规律,孔隙介质中气- 液-固(蜡)流动规律,气、液、固(蜡)相变化和分布特征. 归纳凝析油流动方式为携带、贴壁爬行、界面流、脉冲流、段塞流、溪状流、连续流、小液滴随大液滴和液流汇聚的运移规律. 提出蜡沉积吸附在多孔介质表面. 一种从气相中析出,直接以片状吸附在多孔介质表面. 另一种是蜡在液相中以絮状物析出并影响液相流动. 固相蜡析出使孔隙结构发生变化,孔隙半径变小,出现气、液、固多相流动,流动阻力增大. |
| 关 键 词： | 蜡沉积 凝析液 吸附 运移 流动方式 流动特征 |

| Abstract: | An microscopical experimental method was brought out to study the flow law and flow rules of gas-liquid-sold complex flow in condensate reservoirs with wax deposition. Real porous media were modeled by the phantom micro-model with similar pore structure. The experiments were carried out in porous media at high temperature and high pressure to observe the forming,distribution and flow rules of gas-liquid-sold complex flow. The results show the adsorption and migration laws of wax deposition,three-phase flow ... |
