The advantages and disadvantages of oil-based and freshwater-based annulus protection fluids were compared. According to the characteristics of freshwater shortage on offshore platforms, the quality of Bohai sea water was analyzed in detail. The sterilization effect of various fungicides was evaluated by extinction dilution method in the laboratory, and the quaternary ammonium salt YHZWJ-15 was determined as one of the basic components. After that, the method of industry evaluation standard was used to conclude that polyphosphate BH-701 has excellent scale prevention performance. For the most important corrosion inhibitor in the system, BHH-509, which is composed of gluconate, organic amine, zinc salt and organic phosphonic acid copolymer, is successfully compounded by static corrosion rate method. Finally, the polarization curve was used to analyze the action mechanism of the annulus protection fluid, and the basic ratio was seawater + 0.5% YHZWJ-15 + 0.01% BHF-701A + 0.01% thiourea + 0.5% BHH-509. It can reduce the corrosion rate to 0.0051 mm/a and the corrosion inhibition rate can reach more than 95%.
