Abstract: Nearly two-thirds of all oil ever discovered onshore in China will remain in the reservoir at the conclusion of conventional oil recovery processing. As the ever increasing demand due to the rapid growth of national economy has continuous exceed supply,this massive quantity remains as a significant target for China's future oil production. Based on the first potentiality evaluation and experiences and lessons learned from the EOR applications in China,the strategy study and the second potentiality evaluation of EOR for 17 oil fields have been conducted. The results show that with the technology available at present,11.58 million tons of recoverable reserves can be increased. It accounts for 11% of 101.36 million tons of proven reserve evaluated. The study also attempts to determine the role that technology improvements will play in the future development of the remaining resource. It shows that the chemical flooding, especially polymer flooding,is demonstrateing great potential for application in China.The developing strategy and future planning for onshore oil fields in China are proposed on the basis of the evaluation.
