    Abstract
  • The significance of organic acids generated by kerogen on diagenesis and secondary porosity is discussed in the paper. It is considered that those secondary porosity genetically related with kerogen-derived organic acids are resulted from the reactions of organic acids yielded by and accumulated in kerogen to minerals in rocks; meanwhile it is suggested that the residual acids generated by kerogen in formation relative to their total yield (expressed by the product of per unit weight yield of residual acids by kerogen, the content of organic acids and thickness of formation), the ratio of Σ binary-acid and Σ mono-acid can be employed to predict the intervals with well-developed secondary porosity.
