摘要
Abstract
The compatibility difficulty of inclined section casing is analyzed.The maximum borehole permissible curvature of common casing in horizontal well section of horizontal well and the maximum flexural length of a casing that can be passed under a specific borehole curvature are calculated in Changqing oil field.It is showed that the max curvature of casing is larger than actual train curvature before running casing inclined section.The more appro-priate simplification of mechanical model for the drilling assembly has been proposed.The equivalent rigidity of the drilling assembly has been calculated with method of weighted mean to obtain the stiffness matching coefficient of different well drilling assembly and casing,which provides theoretical support for inclined section casing of the hori-zontal well going down to the predetermined position smoothly.关键词
