摘要

油田开采的原油主要是高蜡原油。当温度降至蜡外观温度（WAT）以下时，石蜡沉淀、结晶并形成三维网络结构，从而降低原油流动性。这给石油开采和运输以及成本控制带来了巨大挑战。迄今为止，添加化学降凝剂是提高原油低温流动性的一种方便、经济的方法。综述了原油降凝剂的种类及其性能机理，介绍了含蜡原油降凝剂性能机理研究的主要方法和进展。最后，展望了降凝剂的发展方向。

Research Progress and Discussion of Waxy Crude Pour Point Depressants: A Mini Review

The crude oils exploited in oilfields are mainly high-wax crude oils. Paraffins precipitate, crystallize, and form a three-dimensional network structure, when the temperature falls below the Wax Appearance Temperature (WAT), which decreases crude oil fluidity. This poses huge challenges to oil exploitation and transportation, as well as cost control. To date, the addition of chemical pour point depressants has been a convenient and economical method to improve low-temperature fluidity in crude oils. This article reviews the types of pour point depressants of crude oil and their performance mechanisms, and introduces the main research methods and progress made in the study of the performance mechanisms of pour point depressants in waxy crude oils. Finally, the development direction of pour point depressants is prospected.
