Basin oil and gas resource overall evaluation method and device

The invention provides a basin oil and gas resource overall evaluation method and a basin oil and gas resource overall evaluation device. The method comprises the steps: predicting the oil and gas resource type of a target basin according to a preset conventional-unconventional oil and gas classification evaluation standard; and calculating the resource quantity of each oil and gas resource type by adopting a resource quantity calculation method; establishing a conventional oil-unconventional oil and gas classification evaluation standard by utilizing the oil and gas enrichment characteristicof the single oil and gas resource type based on the prediction type, the prediction object, the distribution of the prediction object and the oil and gas reservoir characteristic. The invention aimsat the blank and deficiency of the existing oil and gas resource exploration technology. A conventional-unconventional full-type oil and gas resource overall evaluation standard and prediction processof a basin from geology to
