The article deals with a hypothetical model of the molecular structure of degassed and gas-saturated oils developed on the basis of the J. I. Frankel’s hole theory of liquid. Based on this model, the author of the article obtained semiempirical dependences for calculating compressibility factors of degassed and gassaturated oils. The fact that the obtained dependences are based on the noted model gives the necessary physical validity to them and the specific physical content to the empirical parameters contained in them. As a result, semi-empirical dependences become theoretical. Corresponding calculations confirm that their scope broadens as the types of oils and conditions for their finding.
