The most important motivated mechanism which caused the heavy rain in Fuyuan and Malong is the coupling of stronger ascending motion and profound saturation air column.
强降水发生时有强的上升运动与深厚饱和气柱互耦结构是富源、马龙大暴雨产生的重要动力机制。
Infiltration of rainwater during heavy rain increased soil saturation, sharp dropped in suction and caused a substantial decline in shear strength.
暴雨过程中雨水的入渗导致土体饱和度增加、吸力锐减并引起抗剪强度大幅下降。
The steam flood can improve heavy oil seepage flow characteristics, remain oil saturation, and enhance oil displacement efficiency, conformance factor as well as EOR.
因此，注蒸汽热采可以改善稠油渗流特性，降低残余油饱和度，提高驱油效率、波及系数及采收率。
