Abstract: Seismic channel integral is one of the seismic analysis technology of using transformed relevant velocity profile, it is similar to the GLOG technology which utilize the wave resistance profile to analysis the stratum but the former have the advantage of reflecting tiny changes in sandy stratum of the high velocity.#br#The method of sand layer definition will be more simple and accurate.The processing velocity is gained at higher speed and costs cut by this method.After the layer definition, the profile could almost substitute that of joining drilling section with oil bearing.#br#The authors of this paper have received the satisfactory effect using this method in East China Sea.
