Abstract: The difficulty in reservoir evaluation with the diversity of mud-logging parameters lies in parameter normalization and quantitative evaluation of these parameters. The heterogeneity of buried hill reservoir makes it difficult to establish a unified model, and the diversity of reservoir space limits the effectiveness of evaluating buried hill reservoir by simply applying macroscopic physical property characteristics. The physical property index P is proposed to characterize the physical property of buried hill reservoirs. The positive parameter coverage area method is used to evaluate the oil and gas properties of buried hill reservoirs by multi-parameter integration of gas logging, geochemical logging, three-dimensional quantitative fluorescence logging, element logging, diffraction logging, etc. The physical properties and oil-bearing properties of buried hill reservoirs are integrated to determine the standard of effective buried hill reservoirs, which provides a new method for evaluating the effectiveness of buried hill reservoirs. The multi-parameter fusion method for evaluating the effectiveness of buried hill reservoirs was applied in 16 wells that encountered basement in Lishui-Jiaojiang block, and the evaluation standard of buried hill reservoir effectiveness was established. The standard was applied to the interpretation and evaluation of new drilling, and the coincidence rate reached to 94.4%, which achieved good application results.
