Abstract: Offshore oil recovery technological development will bear a direct influence on effective development of China offshore oil reserves and further improvement of the recovery factor of offshore oil and gas fields, following the efforts to infill adjustment wells of offshore oil and gas fields and tap the potential for increase of production through conventional stimulation measures. In the new period of China offshore oil and gas development, the oil recovery technology development pursues a general principle of accelerating the pilot development and attaching importance to concentrated development. Based on the actual conditions, CNOOC comes up with the orientation for oil recovery technological development and work proposals. The pilot technological development includes offshore heavy oil thermal production, development of offshore low-permeability oil and gas reservoirs, chemical flooding stimulation, gas-injection, and microbial enhanced oil production. The orientation for concentration of integrated technology aims mainly at the technological application systems, such as water injection and treatment, ESP process, reservoir protection, well completion and workover, and anti-corrosion, antiscaling and anti-wax process. The efforts will be also focused on some key issues affecting implementation of the strategy, such as talents, technological research and management capability.
