| Abstract: |
| The emphasis in this paper includes acoustic four pivotal techniques such as the standardization of logging data in the processes of inversion,extraction of seismic wavelets,transition of the relations between time and depth,and construction of the models for the initial acoustic impedance with the aid of the principles of Jason software and geological,seismic and logging data;the development and distribution of sandstones in the key trap sections in the second member of the Shuangyang Formation,and the cause of the disadvantages of various wells in the same tectonic traps.These results of research may provide reliable information for the future study of hydrocarbon reservoirs. |
