viscous crude oil production

基本解释

Along with the oil well depth increasing, difficulties in viscous crude production and more and more complicated oil wells, the pumping rods break off usually.
但是目前螺杆泵的形式几乎全部为地面驱动、抽油杆连接，随着井深的增加，稠油的开采，油井的复杂，抽油杆断脱现象非常突出。
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。
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。

稠油开采
With the development of the petroleum technology, steam soak and steam drive technique in the viscous crude oil production have been matured, while the advantage that exploites the superviscous oil applying horizontal well becomes more and more obviously.
近年来,随着石油工业技术的发展,稠油开采中的蒸汽吞吐和蒸汽驱技术日趋成熟,水平井在开采稠油方面的优势也越来越明显。
