Swelling is a concept in polymer physics, which describes the phenomenon that cross-linked polymer don’t dissolve but swell in the solvent. In recent years, the initial migration/ expulsion of hydrocarbon based on the theory of polymer dissolution (solution theory polymer) and swelling method. The method was firstly introduced by Rittter. Ertas gave a swelling test technique for determining the retaining ability of kerogen. The existing data show that the degree of kerogen swelling capability decreases with the increase of burial depth and maturity, and has a close relationship with the attention of micro pores. Cai (2007) and Zhang (2008) used Ritter swelling technology prediction of hydrocarbon in the kerogen in hydrocarbon retention amount. The results show that Ritter, who seems too high an estimate of each component in the kerogen in hydrocarbon retention amount. According to Kelemen, at different temperatures, the swelling ratio of 30-150°C was slightly different. This temperature covered the geological conditions, and the vast bulk of hydrocarbon generation temperature range, which means 30°C under the measured swelling ratio (hydrocarbon retention capacity) can represent geological conditions of organic matter hydrocarbon generation of the vast most of the temperature range under different sets of points of kerogen and the swelling hydrocarbon retention characteristics. But it is still in the initial stage, is not perfect, the previous research methods cannot carry out the research of material differentiation.
