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. 摘要曙光油田老区稀油油层埋藏深，产能低，应用普通泵加深泵挂进行深抽实际效果不好。
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. 采用在注蒸汽过程中向地层掺入稀油的方法来降低地层稠油的粘度，实验研究了超稠油掺稀油后粘度的变化，并按非线性混合方法计算了稠油与稀油混合后的粘度。
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. 摘要在废旧聚烯烃的裂解反应中，聚丙烯的存在，可以提高轻油馏份的收率，增强反应的油化效果，本文称之为聚烯烃裂解反应的增强效应。
