| Abstract: | Expandable liner hanger as a derivative technology of expandable casing,it can effective-ly seal the casing head and the overlapping segments of casings, optimize the depth of side track-ing point in lateral well, as to achieve the product upgrades of conventional hanger. Shengli Oil-field has now developed three types of expandable liner hanger,including casing expandable hang- er,screens expandable hanger and rotating liner expandable hanger,and has achieved industrial applications, involving drilling, completion and workover of petroleum engineering fields. The structural characteristics of the expansion hanger are described and analyzed, its working princi- ple, technical parameters and technological advantages are introduce, combined with field applica-tions of the expandable hanger to optimize the structure design,which obtained a better effect. |
