Quantitative characterization method, system and equipment for geological comprehensive evaluation of oil and gas exploration zone

The invention belongs to the technical field of oil and gas resource geological exploration, and discloses a quantitative characterization method, system and equipment for comprehensive geological evaluation of an oil and gas exploration zone. The method comprises the steps: comprehensively analyzing geological factors of hydrocarbon source conditions, reservoir conditions, cap stratum conditions,trap conditions and reservoir forming conditions of the found oil and gas reservoirs in the oil and gas exploration zone through an oil and gas reservoir fine dissection technology, and defining oiland gas reservoir forming main control factors and enrichment rules; determining the weight of each geological condition subitem index parameter according to the quality evaluation standard of the reservoir forming geological conditions, and performing assignment; and determining the grade of geological comprehensive evaluation according to the comprehensive score of each geological condition. Thesystem comprises a geologi
