| Abstract: | Temperature profiles along the wellore of heavy oil wells with recycling of hot fluid are obtained with a numberical method. Some measures are suggested to improve the effect of wellbore heating. Secondly, stress variations in the sucker-rod are obtained with the node analysis method and a sucker-rod design procedure is given for heavy oil wells. The effect of wellbore heating by hot fluid circulation is evaluated based on the working conditions of sucker-rod and pumping unit. Several sucker-rod design methods widely used are reviewed, and compared with the method proposed in this paper. |
