AI Technical Summary

Problems solved by technology

[0007] (1) Due to the limitation of the transmission environment, the cost of obtaining real formation data is too high;

[0008] (2) The existing virtual geological modeling method is relatively single, and cannot generate a large number of different stratum distribution simulation environments, so it cannot be used to test the robustness of the guided drilling algorithm

[0012] (1) Real data is not easy to obtain

[0013] Geological modeling and visualization rely on raw input data, however, sparse and random insufficient sampling data and predictive fuzzy data from remote sensing make model building very difficult

And for deep wells and ultra-deep wells, it is more difficult to obtain data, and it is expensive to obtain sufficient sampling data

[0014] (2) The formation model is relatively simple

[0015] Based on the geometric shape of spatial entities and their interrelationships, the existing geological modeling methods are relatively simple, and it is impossible to create different virtual formation environments to provide testing environments for the majority of drilling-guiding algorithms, and it is impossible to verify the robustness of the algorithms
