Research on CO₂ EOR Mechanism and Application in Shengli Oilfield

Abstract:

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.
