OIL AND GAS ZONE EFFECTIVENESS EVALUATION METHOD AND APPARATUS

摘要

The present invention provides an oil and gas zone effectiveness evaluation method and apparatus. The oil and gas zone effectiveness evaluation method comprises: obtaining a controlling factor parameter distribution of a target interval, wherein the controlling factor parameter includes: stratum dip angle, fault, unconformity within an effective hydrocarbon generation range, reservoir thickness, cap rock thickness, oil generation, abundance and gas generation abundance; obtaining an evaluation parameter lower limit value of an industrial oil and gas reservoir, wherein the evaluation parameter includes: reservoir thickness, porosity, cap rock thickness, oil generation abundance and gas generation abundance; 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. The present invention provides an oil gas zone effectiveness evaluation method and apparatus that is capable of improving the evaluation coincidence rate.
