摘要
The production of crude oil has three stages: formation drive, wellbore lifting, and pipeline transportation. This paper summarizes the application effects of flow improvers within several long-distance pipelines in China The effects of oil- and water-soluble viscosity reducers on lower- and higher-viscosity heavy oils, respectively, and their effects in the wellbore-lifting process are outlined. Further, the technical difficulties and potential solutions associated with driving heavy oil are discussed. This paper has reference value for researchers conducting studies on flow improvers.
