Embodiment 1
[0051] see figure 1 It is a schematic flow chart of a reservoir oil and gas-bearing mud logging interpretation method provided by Embodiment 1 of the present invention. The method includes the following steps:
[0052] S11, establishing a mud logging interpretation database;
[0053] It should be noted that the mud logging interpretation database is the basis for characterizing reservoir fluid properties through parameter reconstruction. By collecting gas logging data, engineering parameter logging data and oil testing data, the oil testing data is used to characterize the production layer, and the mud logging interpretation database is created based on the oil testing conclusion.
[0054] S12. Extract effective parameters from the mud logging interpretation database, and perform parameter reconstruction through the effective parameters to obtain the reservoir gas logging surface oil and gas index and the reservoir engineering parameter mud logging physical property index;
