| Abstract: | A wellbore security device with sealed tubing and annulus was designed in response to spatial changes of wellbores in rod pumping systems. Setting and unseting processes of the rubber sleeves were analyzed based on principle of volume invariance. Mechanics models of the rubber sleeves were established, and the well startup and shut-in forces under different pressures were studied. A new equipment of sealed rods was developed to solve the wellbore security problems in thermal recovery and rod lifting of offshore heavy oil. |
