中国陆上油田采用常规方法开发，约有三分之二的储量留在地下。由于迅速发展的国民经济对石油能源的需求不断增长，提高已开发油田的采收率在今后一段时间仍是一项不可忽视的发展方向。原中国石油天然气总公司于1987年和1996年开始对中国陆上13个和17个油田系统地进行了二次提高采收率潜力评价和发展战略研究。该项研究以第一次提高采收率潜力评价为基础，充分吸收了我国已实施的矿场试验项目的经验和教训，从技术和经济两个方面对我国提高采收率的发展远景以及近期内可实现的、技术和经济都可行的潜力进行了再认识。评价结果表明：由于我国主要油田非均质程度高，提高采收率的潜力很大。在现有技术条件下，从参加评价的101.36×108t地质储量中可增加可采储量11.58×108t，平均提高采收率11%以上。如果按目前全国陆上油田平均采收率33%计算，相当于新发现约35×108t的地质储量。同时也指出，由于技术，特别是经济条件的限制，近期内可在油田开发中推广应用的技术主要是聚合物驱方法；复合驱需要进一步完善技术，降低成本，才可能在油田中大规模应用。本文在此评价的基础上，提出了我国陆上油田提高采收率近期的规划设想和发展战略。

Nearly two-thirds of all oil ever discovered onshore in Chinawill 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,1158 million tons of recoverable reserves can be increased. It accounts for 11% of 10136 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.
