Problems solved by technology

[0003] The evaluation objects of existing evaluation methods are mainly zones, traps, or depressions in basins, etc., which cannot meet the current needs of my country's piedmont exploration field to evaluate deformation zones based on deformation structures.
However, the qualitative evaluation based on the basic geological conditions of oil and gas in the deformation zone, the strength of structural transformation, and the scale of the deformation zone is relatively subjective, so there are problems of inaccurate evaluation results.
