The old light oil reservoirs in Shuguang Oilfield are deeply buried and low productive.The effect is poor by deepening pump depth with common pumps. 摘要曙光油田老區稀油油層埋藏深，產(chǎn)能低，應用普通泵加深泵掛進(jìn)行深抽實(shí)際效果不好。
The change of superheavy oil viscosity after mixing light oil was studied by the experiment, and the mixed viscosity was calculated by non-linear mixing method. 采用在注蒸汽過(guò)程中向地層摻入稀油的方法來(lái)降低地層稠油的粘度，實(shí)驗研究了超稠油摻稀油后粘度的變化，并按非線(xiàn)性混合方法計算了稠油與稀油混合后的粘度。
