A method and apparatus for evaluating volumes of discharged hydrocarbon and externally charged hydrocarbon in a mud shale. The method comprises: determining a hydrogen index and a current hydrocarbon generation potential parameter of a mud shale in target block based on total organic carbon test data and pyrolysis analysis test data of the mud shale; determining an original hydrogen index of the mud shale based on the hydrogen index and the pyrolysis analysis test data; and evaluating a volume of discharged hydrocarbon and a volume of externally charged hydrocarbon in the mud shale based on the current hydrocarbon generation potential parameter and the original hydrogen index.

A method for quantitative evaluation of self-sealing property of organic-rich shale includes: S1, selecting geological parameters for evaluating the self-sealing property of the organic-rich shale; S2, taking organic-rich shale samples, and measuring the geological parameters of each sample; S3, calculating a weight coefficient w; of each geological parameter; S4, calculating a self-sealing evaluation coefficient S, and correcting the S to obtain a corrected self-sealing evaluation coefficient S'; S5, establishing a self-sealing evaluation standard of the organic-rich shale according to the S′, wherein if S′≥0.6, the self-sealing grade is excellent, if 0.45≤S′<0.6, the self-sealing grade is good, if 0.3≤S′<0.45, the self-sealing grade is medium, and if S′<0.3, the self-sealing grade is poor. According to the method, the self-sealing property of the shale is quantitatively evaluated, and the preservation condition of the shale gas in the shale formation can be more accurately predicted.
