| Abstract: | In order to solve the problems concerning the severe sand production,easy pipe-sticking and insufficient lifting of workover rig during the production of viscous oil well,the force boosting device for service wellhead is developed.The device is mainly made up of inner tube,outer tube,piston tube,end cover,retaining ring,hanger,liquid-route element and sealing element.The field application indicates that used together with the workover rig,the force boosting device can make most of the stuck viscous oil wells released.With reasonable design and simple operation,the device almost has no safety risk of releasing the stuck string,thus improving the maintenance efficiency for viscous oil well. |
