Result This technique has effectively improved vertical utilization degree of super heavy oil formation and increased the crude production.

结果分注选注技术有效地提高了超稠油油层纵向动用程度，提高了油井产量。

With the decline of conventional crude oil production, heavy oil exploitation become more and more important.

随着常规原油产量的递减，稠油开采对缓解能源供求紧张意义重大。

The viscosity of crude oil from viscous oil reservoir is high and heavy hydrocarbon components constitute the majority. So, it is difficult to produce oil from production Wells.

由于稠油段油层原油的粘度高，重烃组分所占比例大，因此造成采出井采出困难。

The Saudis had 1.5 million bpd of spare production capacity--oil spigots on standby--and it was less desirable heavy crude.

World crude oil production has in some cases already peaked (sweet, light) while others (heavy, sour) it has yet to be will soon.
