There is an oil and gas zone effectiveness evaluation method. The oil and gas zone effectiveness evaluation method has the steps of: obtaining a controlling factor parameter distribution of a target interval; obtaining an evaluation parameter lower limit value of an industrial oil and gas reservoir; obtaining an accumulation parameter value of each grid coordinate point according to the controlling factor parameter distribution; obtaining an evaluation parameter processing value of each grid coordinate point according to the evaluation parameter, the evaluation parameter lower limit value and the accumulation parameter value of the grid coordinate point; and obtaining a zone evaluation value of the target interval according to the evaluation parameter processing value of the grid coordinate point. There also is an apparatus that is capable of improving the evaluation coincidence rate.

According to some implementations, the present disclosure relates to a method and apparatus for evaluating exploitation value of a geological resource. In one implementation, a method includes: acquiring geological parameters of a geological structure in multiple designated dimensions, wherein the geological parameters are used for characterizing a state of the geological structure in the designated dimensions; matching the geological parameters with a threshold of each of the designated dimensions, respectively, to obtain a characterization value of each of the designated dimensions; forming a characterization vector from the characterization values of the designated dimensions; and performing an evaluation operation based on the characterization vector to obtain an evaluation value of the geological resource in the geological structure. The exploitation value of a geological resource can be evaluated by taking the effect of a threshold of the geological resource on the exploitation value of the geological resource into full consideration.
