Zusammenfassung:The invention discloses a prediction method for river facies source reservoir ex-situ tight oil and gas sweet spot area distribution, and belongs to the field of oil and gas exploration. The method comprises the following steps: determining actual hydrocarbon source rocks from natural gas and crude oil in target river sand according to historical data; establishing a TOC logging calculation modelof the actual hydrocarbon source rock according to the actual hydrocarbon source rock, the rock core data and the single well logging data, and drawing hydrocarbon source rock plane distribution according to the TOC logging calculation model and well point distribution; carrying out reservoir interpretation according to historical data, and drawing reservoir plane distribution; according to the post-stack crack detection method and historical data, carrying out crack prediction analysis and hydrocarbon reservoir fracture profile analysis, and drawing a crack prediction plane graph and a hydrocarbon reservoir fracture
