  • Abstract:
    Digital transition and intelligent development are necessary paths for upgrading levels and improving quality and efficiency of mature oilfields. Application progress and significant achievements of AI techniques in wa⁃ ter flooding development in Daqing Placanticline oilfield are presented，with particular emphasis on positive effect of key techniques of intelligent well logging interpretation，reservoir prediction by intelligent well-seismic tie，water injection optimization adjustment based on data mining，and intelligent optimization of stimulation wells and reser⁃ voirs in enhancing efficiency，effectiveness and economic benefits of oilfield development. Through technological in⁃ novation，natural decline rate by water flooding in Daqing Placanticline oilfield is controlled to <7%，and annual water cut increase is controlled to less than 0.2 percentage points，realizing high-level and high-quality oilfield de⁃ velopment in late stage of ultra-high water cut. On this basis，intelligent development direction of water flooding technology is prospected，suggesting that application of large language models should be accelerated for oil and gas，research and development of real-time dynamic monitoring techniques should be enhanced，and techniques of digital twin models，intelligent plan design and smart injection-production optimization should be adopted，so as to promote higher-level intelligent transform of oilfield development. © 2024 Editorial Department of Petroleum Geology and Oilfield Development in Daqing.
