The Application of Separation Technology in Seismic Semblance Background to Reservoir Prediction of Beach-Bar Sandbody——Case of Es4 Sandbody in the Area of Dongying Sag of Jiyang Depression

Li Junliang(SINOPEC Shengli Geological Scientific Reserch Institute,Shandong Dongying 257015)  
The beach-bar sandbodies of the Es4 in Dongying area are of the complex geologic characters of thin sand-in-mud layer and lateral variation large,complex distribution.Separation technology based on seismic semblance background can reveal more reflecting features of thin layers on seismic profile.A scheme of separation technology of semblance background has been built and applied to the reservoir prediction of beach-bar sandbodies of the Es4 in Dongying area.The results show that the seismic data resolution is raised,the more features of thin layers in seismic profile are revealed.This technology can display accurately the reservoir lateral variation in detail on the main target layers and instruct effectively oil and gas exploration in the area.
