Deep strong heterogeneous gas reservoir partition evaluation method

The invention discloses a deep strong heterogeneous gas reservoir partition evaluation method, which relates to the technical field of oil exploration, and comprises the following steps: taking a parameter related to single well open-flow capacity as one of basic parameters for partition evaluation; a correlation coefficient analysis method is used for analyzing the correlation between the multiple parameters and the single well open-flow capacity, and main control factors are screened out; performing regression analysis on a relational expression between the main control factor and the single well open flow capacity, establishing a gas reservoir partition evaluation plate based on a single factor according to the regression relational expression, and drawing a related map; determining a training set and an attribute set according to the specificity of a random forest method, and outputting a complete decision tree; obtaining a gas reservoir gas well open-flow capacity classification standard, and obtaining a
