The invention discloses a method for oil-gas-water identification based on physical property and gas logging parameter intersection. The method comprises the following steps: reading the C1-C8 average of test well sections by collecting site gas logging data, well logging interpretation porosity data and oil testing data, performing parameter reconstruction, obtaining a TCS parameter, building a plate, determining limit of various fluid properties in the plate, performing on-site verification, and performing popularization and application in more wells on the site if no error occurs. The method solves the problem of immoderate reliance on software identification and hardware developers, enriches existing technical means, improves well drilling oil-gas-water layer identification efficiency, reduces identification difficulty, improves technical levels of field workers and also has the effect of promoting later-period oil-gas-water identification and instrument popularization.
