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，產能低，應用普通泵加深泵掛進行深抽實際效果不好。
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. 採用在注蒸汽過程中向地層摻入稀油的方法來降低地層稠油的粘度，實驗研究了超稠油摻稀油后粘度的變化，並按非線性混合方法計算了稠油與稀油混合后的粘度。
The existing of poypropylene can raise the liquid fraction ratio, especially the light oil ratio, so it can fortify the effect of the cracking reaction of polyene to light oil. 摘要在廢舊聚烯烴的裂解反應中，聚丙烯的存在，可以提高輕油餾份的收率，增強反應的油化效果，本文稱之為聚烯烴裂解反應的增強效應。
