In order to seek out a new way to enhance recovery factor by steamflood, a pilot test area of steamflood has been set up in this oil field.
为了探索利用蒸汽驱方式提高采收率的新途径，在该油田开辟了蒸汽驱先导试验区。

The steamflood 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。

Good recovery result had once been achieved by steamflood, however, because of invasion of edge and bottom water, the ultimate recovery factor of steam soaking is low.
