Abstract
At present,most of crude oil produced in China belongs to high-condensation waxy crude oil,which has poor fluidity and stoppage at low temperature,and is likely to cause condensate tube accidents,bringing a heavy negative impact on crude oil transportation,processing,storage,etc.Therefore it is very important to develop coagulants.Surfactant,polymer and compound types of pour point depressants are respectively described.The action mechanism and selection principles of pour point depressant are analyzed,the existing problems are listed,and the development and improvement direction are proposed.
