Aiming at erosion-corrosion of oil casing material in multi-phase flow, the erosion-corrosion behavior of N80 steel in liquid-solid two phase flow fluid which containing silica sand and sodium chloride at different pH values and the influence of flow velocity and concentration of chloride ion on the synergistic effect were investigated by using a rotating cylindrical electrode device and an electrochemical workstation combined with electrochemical testing method and weight loss method. The results show that with the increase of pH value, the polarization resistance of N80 steel increases, and the radius of capacitive reactance arc on EIS increases, the corrosion current density and the corrosion rate decreases simultaneously. N80 steel exhibits activation dissolution characteristics in liquid-solid two-phase flow fluids with different pH values. The whole corrosion process is controlled by cathodic reduction reaction. Synergism is the main cause of material mass loss when the flow rate and concentration of chloride ion change respectively. The variation trend of synergism with each influencing factor is consistent with that of total erosion-corrosion rate. [ABSTRACT FROM AUTHOR]

Silt-erosion corrosion of wellhead devices is very severe in the initial stage of production in shale gas field, which affects the safety and economic benefits of gas extraction seriously. In order to develop effective control programs and research the damage behavior of materials under sanderosion conditions, this paper took L360N pipeline steel as target, using the methods of jet impingement erosion experiment, weight loss and morphology observation, then the influence law of sand content and angle impact on erosion corrosion damage of material under simulated liquid-solid erosion condition was studied. The results showed that the greatest mass loss was occurred at the sand concentration of 7 wt% and the lowest was occurred at 3 wt% under the conditions of 8 m/ s flow velocity and 90° impact angle. The cumulative mass loss after 240 min erosion-corrosion at the sand concentration of 3 wt% was approximately 52 % of the sand concentration of 7 wt%. Moreover, the severest and lightest damage occurred at the impact angle of 30° and 60° respectively under the conditions of 8 m/ s jet velocity and 5 wt% sand concentration, the mass loss of the latter is about 48 % of the former.
