腰英台油田CO_2～地层原油体系相态变化研究

Study on Phase Conversion of Carbon Dioxide and Stratum Crude Oil of Yao Yingtai Reservoir

本文通过CO2加气膨胀试验,研究CO2注入过程中DB22-7-3井青一Ⅱ段油藏地层原油相态的变化情况。

Through swell experimentation by adding Carbon dioxide, we study the stratum crude oil phase conversion of the first member of QingShankou Formation reservoir in DB22-7-3 well.
