Corrosion Analysis of Rubber Sleeve during CO2 Miscible Flooding Experiment

CO2 miscible flooding is an important method of improving oil recovery in low permeability reservoirs. The most important parameter of CO2 miscible flooding is the minimum miscibility pressure(MMP) between CO2 and crude oil.

Description
Summary:CO2 miscible flooding is an important method of improving oil recovery in low permeability reservoirs. The most important parameter of CO2 miscible flooding is the minimum miscibility pressure(MMP) between CO2 and crude oil. In this paper, the coreflood method was used to measure MMP, but it was found that the rubber sleeve of the core holder was seriously corroded, which resulted in the rubber sleeve with ring pressure and worse safety of the experiment. Therefore, in this paper by the means of theoretical analysis, experiment observation and comparison of the rubber sleeves before and after corrosion process, the corrosion mechanisms were analyzed. The research results will give some advises for further similar experiments.
