原油改性剂对原油防蜡与降凝性能的研究

大港滩海油田大多数油井原油的沥青质-胶质和蜡的含量都较高，在生产过程中存在方面的问题由于结蜡，产量不稳定，原油黏度大，用通常的采油技术工艺无法生产地层堵塞，产量逐渐下降，甚至变成死井。为解决这些问题，选择张海13-21L井进行原油改性防蜡剂的室内研究，并制定了现场试验方案，研究改性剂对原油的防蜡和降凝性能。

Study on Paraffin Inhibiting and Viscosity Reducing Properties of Wax Inhibiting Agent for Crude Oil

The content of asphahene-glial and wax crude oil produced by most of the oil well in Dagang oilfield is very high. The existence of the wax increases the production instability and oil viscosity in the production process. And the usual technique can＇t produce oil formation blocked, the gradual decline in production, and even well into the death. To solve these problems, we select 13-21L Zhanghai well indoor Paraffin Inhibitor research and developed a field test program to study paraffin inhibiting and viscosity reducing properties of wax inhibiting agent for crude oil.
