Through analysis of data such as core thin sections and whole rock analysis, it was found that the intensity of rock alteration has a significant impact on the production capacity of metamorphic rock buried hills in A Oilfield. Therefore, effective evaluation of reservoir alteration intensity is crucial for predicting the production capacity of metamorphic rock buried hills. The indicator coefficient F for reservoir alteration was constructed using neutron porosity curves and deep shallow lateral resistivity curves, and combined with logging interpretation of porosity, the reservoirs in the metamorphic rock buried hill of A oilfield were divided into three categories: Class I reservoirs are high production layers, with a specific oil production index greater than 10t/d/MPa/m, an alteration indicator coefficient F < 1, and a porosity ≥ 3%; Class II reservoirs are relatively low production layers, with a specific oil production index between 0 and 10t/d/MPa/m, an erosion indicator coefficient F ≥ 1, and a porosity ≥ 3%; Class III reservoirs are non producing layers, and logging curves show tight layers or lithological intrusions with a porosity < 3%. On this basis, a productivity evaluation factor S was constructed using deep and shallow lateral resistivity and Stoneley wave time difference, and a productivity evaluation model for oil field a was established for each reservoir type. The production capacity of metamorphic rock buried hill wells in A oilfield was predicted using this method, and the relative error between the predicted results and the actual test results was 7.8%. The accuracy of production capacity prediction is high, which has important reference significance for production capacity prediction in similar oilfields.
