Abstract: Facing the development bottlenecks of old high and ultra-high water-cut oilfields, Daqing Oilfield launched a special key project focusing on further improvement of EOR technology for the oil reservoirs which were brought under development and in their ultra-high water-cut period. The oilfield established the “three-in-one” management system – an integration of research, experiment and application – to bring about orderly connection and high-efficiency integration of the R&D tasks. It created the research model that was based on high-end cooperation, introduction of systems, collaboration and sharing, and cross-disciplinary coordination within the enterprise. Based on the joint research efforts, Daqing Oilfield integrated and innovated the systematic technologies of waterflooding and water control for higher performance. Meanwhile, it also developed and perfected the systematic technologies to improve the quality and performance of polymer for the oil layers of the Class II. As a result, the new technology was developed to substantially improve EOR on the basis of ASP flooding and cost-effectiveness, enabling Daqing to become an international leader in this area. This technology helped Daqing Oilfield replace its backbone development technology, effectively keep its oil production stable at 4000×10⁴t and implement its development strategy. The additional crude oil production was accumulated to 4900×10⁴t in a duration of 13 years. The innovative results have been extensively used both at home and abroad, making Daqing a domestic leader in bringing the oilfields of the same king under high-efficiency development. The joint research model, which is an integration of industry, universities and research institutes, can be put into duplication and extension.
