Time-frequency analysis method has been applied in many fields, and it acquires a great of achievements. Choi-Williams time-frequency method is proposed for array acoustic logging signal analysis to identify different reservoirs. Choi-Williams distribution has apparent physical significance. The Choi-Williams energy distribution has different characteristics under different time and different frequency, which is applied to identify oil and water layers. Good result has been achieved.
