At present, a large amount of oil reserves are in their late stage of super high water cut in Shengli oilfield. How to understand the potential of improving the recovery of this part of resources is a strategic issue closely related to the long-term development of oilfield. Based on the production practice and the laboratory research results, sustainable development ideas and research proposals were proposed aiming at reservoirs with super high water cut in the late stage. There is also abundant of reserves accumulating in extra.low permeability and tight oil reservoirs in Shengli oilfield. How to make a cost-effective development and recovery improvement of this kind of resources will be the main issues to face. Suggestions about key technique breakthroughs, supporting technology researches, development means of supplementing energy and so on are presented for the extra low permeability reservoirs. In addition, with the acceleration of the city planning and construction pace, the oil field development has become to be performed in city-center today otherwise in salt wasteland before. It is more and more common that reserves of great development potential are under ground with no space for development drilling; and the corresponding construction and management model have been proposed.
