Indoor Research of Injection Well Reservoir Damage Factors in Bohai P Oilfield
For the Bohai P oilfield, the existing main problems are high water injection pressure, water injection difficulty, low injection-production ratio, formation depletion and low recovery degree. In view of the main problems, the research of water injection damage mechanism was carried out. First the reservoir engineering method was to analyze the water flooding damage degree. Then the core flow experiment was performed to validate the influence of water quality, water scaling, clay swelling, and the “cold damage” on the water injection block. Eventually the main damage
