Resumo

In this paper, a review work based on the polymer flood for offshore heavy oil reservoir is presented. In recent years, the CNOOC has launched quite a few chemical EOR projects at offshore oilfields in the Bohai Bay, China. With the useful life of platform and the present production state, polymer flooding is considered and already proved as an important technology for the strategic development of offshore heavy oil fields in the Bohai Bay. Up to 2010, there were three polymer-EOR projects on heavy oil field with the water cut between 10 and 80%. And about 20,000 tons polymer powder was used in 27 wells in the past 5 years. It has been seen that the water cut declined while the oil production increased. The application result shown is feasible. The procedure of polymer injection is presented in this paper.
