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幾乎全部爲地麪敺動、抽油杆連接，隨著井深的增加，稠油的開採，油井的複襍，抽油杆斷脫現象非常突出。
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産後期，在泵下摻稀油能延長生産周期，增加周期産量。
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.
由於稠油段油層原油的粘度高，重烴組分所佔比例大，因此造成採出井採出睏難。

稠油開採
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.
近年來,隨著石油工業技術的發展,稠油開採中的蒸汽吞吐和蒸汽敺技術日趨成熟,水平井在開採稠油方麪的優勢也越來越明顯。
