viscous crude oil production

During the late period of steam stimulation, mixing viscous crude oil with pumped down light oil can prolong the production period and increase the cumulative oil production.

稠油油田蒸汽吞吐井生产后期，在泵下掺稀油能延长生产周期，增加周期产量。

Thermal production, which is used in Liaohe oil Field as a main method to explore viscous oil, gives rise to the artificial increase of CO2 content in the crude produced from well.

辽河油田稠油开发主要以热力采油为主，人为地使油井采出物中二氧化碳的含量增加。

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。
