Abstract: In 1stmember of Zhujiang Formation in A oilfield of Wenchang,the reservoir lithology and physical properties can not be recognized by measured acoustic wave,density log and the calculation of the wave impedance in this area,due to the effects of such factors as special lithology and wall collapse,thus leading to difficulties in predicting the reservoir. The multi-well logging and seismic attributes were utilized in integrated way to invert lithological characteristics for different target zones,and the reconstruction processing was conducted for sonic curve. The curve can represent the real features of the reservoirs and can also significantly enhance the resolution of acoustic impedance inversion profile and the capability of reservoir description and prediction. Practical application of this technique is very successful.
