Abstract：At present, conventional logging is mainly used to identify the lithology of metamorphic rock and then evaluate the reservoirs, while array acoustic logging is seldom used to evaluate the effectiveness of metamorphic rock reservoirs. Therefore, given the logging data of metamorphic rock in Bozhong 19-6 (BZ19-6) gas field, the response characteristics of array acoustic logging are analyzed, and the average attenuation calculation method is proposed on the basis of the conventional acoustic parameter calculation. By the quantitative study of the correlation between various acoustic parameters and different reservoirs, nine acoustic parameters sensitive to effective reservoirs, such as the time difference of longitudinal wave, shear wave, and Stoneley wave, array attenuation, and average attenuation, are extracted, and the evaluation chart and scheme of reservoir effectiveness based on sensitive acoustic parameters are established. The new well data are processed by the proposed method, and the reservoir effectiveness is evaluated. The coincidence rate between the evaluation results and the test results is 91.43%, which meets the field application requirements.
