摘要：

As one kind of oil expellant in improving the recovery ration of oil reservoir (EOR), CO2 flooding has merits such as extensive adaptability, low cost, high recoverability, and it will become one main way of EOR in future. In this paper, the EOR mechanism of CO2 flooding has been studied correspond to the geologic conditions in Shengli oil field, which includes three parts: mechanism of expansion, mechanism of reduce oil viscosity and displacement experiment of long core model. Moreover, the detailed process of the test block description of CO2 flooding in Shengli oil field has been set forth. Through the application in Shengli oil field proves that the EOR mechanism of CO2 flooding is right and suits for geologic conditions in Shengli oil field.
