通过摄像法得出了旋涡表面流体质点的运动轨迹、切向和轴向时均速度。
Moving path lines, tangential and axial average velocities of particles at the vortex surface are obtained by the photography method.
基于多孔介质流体质点渗流规律，考虑反凝析油的影响，推导了近似直线供给边界的边水凝析气藏见水时间预测新公式。
Therefore, the prediction formula of the water breakthrough time is derived based on fluid flow in porous media, considering the impact of anti-condensate.
