| Abstract: | Based on the traditional collapse mechanism,technical characteristics of Baosteel anti-collapse casing series were introduced,highlighting on alloying design,texture distribution,high strength-toughness mechanisms and casing string design.The collapse resistance mechanisms were researched from the points of grain refining,precipitation strengthening,and texture optimizing.Three-stage corrosion behavior of the casing series in H2S saturated aqueous brine solutions was proposed.A prediction model of collapse strength was finally constructed for the casing series. |
