Abstract: Shengli Oilfield, as a typical old oilfield in East China, has experienced more than six decades of exploration and development. The geological reserves of more than 6×108t have not been brought under development for the reason of economic performance. Facing a series of difficulties, such as low-grade reserves, high cost for development and limited engineering process, Sinopec Shengli Oilfield Company and Sinopec Oilfield Service Shengli Corporation were engaged in strategic cooperation and innovated the “risks sharing for win-win cooperation” oilfield development mechanism. They came up with three differential cooperative models centering geology-engineering integration--overproduction sharing model, overproduction+ premium sharing model and profit--forming a system of solutions for the different reservoir types and different development stages. Under the new system, the companies promoted technological iteration and innovation, upgraded equipment and facilities and improve managerial integration, making breakthroughs in development of the difficult-to-produce reserves. As the result of collaboration, the reserves of 2.4×108t were put into production while the 380×104t productivity was newly constructed. The annual drilling speed was increased 80 percent and the daily single-well oil production was 1.1 tons higher as compared to the conventional blocks. The balanced oil price dropped to US$46.9 per barrel on average from US$92.4 per barrel. Adoption of the geology-engineering integration models for cooperative production can effectively solve the bottleneck in development of lowgrade reservoirs in old oilfields, create a widely-applicable“ Shengli model” and help China's old oilfields find a scientific way to keep production stable.
