Influence Analysis of Casing Buckling in Extended Reach Well
摘要
Abstract
Applying the fluid dynamics theory,the influence law of casing buckling in extended reach well is simulated.The calculation results show that,with the deviation angle increases,the displacement efficiency decreased.The average displacement efficiency of casing helical buckling is lower than casing si-nusoidal buckling,the displacement efficiency increases with the increasing of displacement velocity,ulti-mately,the flow state turns turbulent flow and displacement efficiency tends to be stable,rotating-casing cementing can increase tangential velocity,which animates the retention drilling fluid out of bottom hole and improves displacement efficiency.Methods on improving displacement efficiency of casing buckling in extended reach well are obtained.关键词
