摘要
Abstract
Nowadays, synthetic water cut in on-shore oil fields reaches 81%.Outputs begin decreasing, as a result, developing enhanced oil recovery by injecting gas becomes a tactic task for sustainable development of on-shore oil industry. The wide range application of CO2 injection based on the success of field test requires further study of mechanism of CO2 miscible flooding procedure. Though it is well known that CO2 decrease oil viscosity by swelling in it, the variation of physical parameters of each phase in the procedure of multiple contact is not well studied. In this paper, the author established a one-dimensional simulation method considering Zhong Yuan oil field to calculate and analyze such parameters as composition, density, viscosity and interfacial tension.关键词
