[0034] An example of the FLAIR gas logging oil-gas-water identification method based on parameter reconstruction in the Bohai Oilfield, such as figure 1 The flow chart of the FLAIR oil, gas and water identification method based on parameter reconstruction includes the following steps:
[0035](1) Collect on-site FLAIR gas logging data and on-site oil testing interval data;
[0036] (2) Read oil test section C 1 -C 8 The average value, the reading method is the geometric mean value of the oil test top depth and the oil test bottom depth section, the specific reading data table is shown in the following table 1 and continued table 1:
