摘要
Abstract
With respect to the difficulty of heavy oil flowing in weflbore, calculating models for lifting techniques by mixing chemical agent in hollow rod or annulus of rod pumping wells are developed with the nodal system analysis method. The models are used to study the conditions for improving the fluid flow ability. The experimental results show that the chemical agent M mixed with heavy oil in wellbore can greatly improve the flow ability of heavy oil. The mechanical conditions of the suck-rod by emulsification and thermal mechanism of agent M can be improved. A certain injecting temperature is necessary at the beginning of injecting the chemical agent M.关键词
