The steam flood can improve heavy oil seepage flow characteristics, remain oil saturation, and enhance oil displacement efficiency, conformancefactor 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。
2
Producing condition of poor reservoir is bad, which makes waterflood efficiency, conformancefactor and final recovery efficiency low, and the development effect is bad.
差油层动用状况较差，导致油田水驱效率和波及系数较低，最终采收率低，开发效果差。
3
Good performance is necessarily a driving factor in the design of Saxon, second only to conformance with the XSLT specification.
