常見例句雙語例句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.但是目前螺桿泵的形式幾乎全部為地面驅(qū)動、抽油桿連接,隨著井深的增加,稠油的開采,油井的復(fù)雜,抽油桿斷脫現(xiàn)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產(chǎn)后期,在泵下?lián)较∮湍苎娱L生產(chǎn)周期,增加周期產(chǎn)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.由于稠油段油層原油的粘度高,重?zé)N組分所占比例大,因此造成采出井采出困難。d.wanfangdata.com.cn 返回 viscous crude oil production
