Oil flooding mechanism to

After nearly 20 years of research and practice, China's chemical flooding in technology, size, effects, etc. have been walking in the forefront of the world. Through nearly 30 mines testing and promotion that polymer flooding can increase oil recovery of 10%, flooding can increase oil recovery of 15% -20%. In 1997, China increased polymer flooding oil reached 303 × 104t, expected "during the" will increase oil 1500 × 104t. China's  Oil machine  are mostly terrestrial sedimentary and continental source, secondary recovery predicted average recovery was 34.2%, nearly one hundred million tons reserves left in the ground. The conditions for China's EOR offers tremendous potential. In the future, China's EOR flooding mechanism to deepen the understanding of the reservoir, reducing the cost and amount of EOR,  pellet machines  depth profile and improve the overall economic benefits of the project and other aspects of strengthening research, to maximize harvest rate and economic benefits.
