FRICTIONAL RESISTANCE ANALYSIS AND CALCULATION OF WASHOVER-STRING IN PROCESS OF EXTRACTING CASING
Based on the existing string mechanicalmodel, the mechanicalmodel of washover-string is built with its structure features (big diameter,thin-wall). After washover-string inflexion condition and contact force areanalyzed, friction resistance of washover-string is calculated and analyzed.
