【 摘 要 】

The composition and structure of pour point depressant/viscosity reducer for pipeline transportation and its application effect in long-distance pipeline transportation in China as well as the application effect of oil-soluble viscosity reducer and water-soluble viscosity reducer for wellbore lift in low-viscosity and high-viscosity heavy oil wells in China are introduced. The main technical problems existing in the study of viscosity reducer for heavy oil formations drive are presented.
