Abstract: The genetic mechanism of immature-low mature oils is explained using theories of chaos and dissipative structure in microphysics. The theoretic basis for genetic mechanism of immature oil and the theoretic model for organic negentropy reaction in microscopic mechanism of hydrocarbon generation are presented. The organic matter and its property for forming the immature oil are applied to demonstrate the microscopic mechanism of the hydrocarbon-generating from acidic non-hydrocarbon and neutral nonhydrocarbon in immature-low mature source rocks. The typical examples, biomarker's maturity index and ZYR rearranged sterane isomeride are discussed. Finally, the accumulation characteristics of immature oil are described in this paper.

Key words: immature oil, low mature oil, microphysics, genetic mechanism, organic matter, microscopic hydrocarbon generation, active molecule, proton acid beam
