Method and apparatus for evaluating volumes of discharged hydrocarbon and externally charged hydrocarbon in mud shale

An apparatus for evaluating volumes of discharged hydrocarbon and externally charged hydrocarbon in a mud shale, comprising:

• a hydrogen index determination module configured to determine a hydrogen index and a current hydrocarbon generation potential parameter of a mud shale in a target block based on total organic carbon test data and pyrolysis analysis test data of the mud shale;
• an original hydrogen index determination module configured to determine an original hydrogen index of the mud shale based on the hydrogen index and the pyrolysis analysis test data;
• and
• a mud shale evaluation module configured to evaluate 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.
