| description | The present disclosure relates to a method and a system for updating a three-dimensional lithology model for precision navigation of deep oil and gas in real time, aiming to solve the problem that an existing while drilling model is difficult to adapt to a real-time update of the model in a strong heterogeneous reservoir, which leads to a decrease in accuracy of an established prediction model and a lack of a drilling ratio. The present disclosure includes: dividing pre-processed seismic data into three pieces of single-frequency seismic waveform data by a wavelet frequency division method; selecting an optimal single-frequency combination according to a correlation coefficient between gamma ray prediction curves and measured curves at different depths; and computing a single-frequency gamma ray prediction model while drilling, updated with drilling, and a full-band gamma ray distribution model while drilling, updated with drilling, by means of the optimal single-frequency combination. |
