Abstract: China’s old oilfields have fully come under their middle and later recovery periods while the quality of oil and gas resources are becoming more and more deteriorating. Increase of reserves on a large scale becomes more difficult. To solve the main contradictions in the different development stages, CNPC established and developed the management model for continual integration of oil production engineering technological innovations, which is an integration of oil production, oil reservoir, drilling and completion technology, and surface engineering, an integration of management of technological systems at four levels of company, factory, mine and crew, an integration of organization for production, research, experiment and promotion, and an integration of modernization for new technology, new products, new process and new standards. Under the guidance of demands, the emphasis is placed on the purposes of research and development, the system of management and adaptability of achievements for application. The research is ensured to be in steps with experiment and promotion and appropriately linked, accelerating transformation of research achievements. The management model for continual integration of technological innovations effectively helps develop featured oil production engineering technologies, such as fine layered water injection, unconventional oil and gas stimulation and fracturing of deep-layer volcanic rock. This management model has been used in Daqing, Jilin, Changqing and Dagang as well as 12 oil and gas cooperative projects in six countries like Kazakhstan, Mongolia and Sudan, achieving the purposes of cost reduction higher production from oil wells, and cost-effective development of low-grade resources. The research and promotion period of the main water-flooding engineering technology is shortened by three to five years as compared to the same kind of technology from the international petroleum community. The transformation rate of achievement exceeds 80 percent. Three key technological innovations are completed while five core processes are unified, seven items of supporting technology perfected, and five industrial standards formulated, rapidly modernizing integration of technology and promoting large-scale application of technology.
