Abstract Crude oil standard density (20℃) is an important item in the physical and chemical indicators of crude oil. By using Anton Paar (Anton Paar) DMATM 35 V4 Ex Petrol explosion-proof portable density meter and other equipment, the density of crude oil samples from oil wells in multiple oilfields were detected by pyknometer method and vibrating-tube densitometer method respectively at 15~80 ℃, the density temperature curve was drawn, the empirical formula was deduced and improved, and a calculation formula with test density and temperature as parameters was given. The oscillating tube density test method and the petroleum meter were combined to calculate the crude oil standard density, and the relative error was controlled within ±0.5%. It is possible to quickly obtain crude oil standard density parameters on-site.
