Seismic Data Interpretation And Reservoir Prediction In Dongying Formation Of LD10-1

This article is based on LD 10-1 oil field as a major area of research,focus on structure interpretation and reservoir prediction for each oil layer of lower Dong ?section.The structure of LD-10-1 oil field is complex,seen from the structural characteristics of basal trunk is affected by slope slip fracture of complex fault-block structure.Current problems in seismic data: 1)LD 10-1 high parts 1th fault in LiaoXi and its associated faults in the Dong?section the targets under the breakpoint is not clear,Low signal to noise ratio of seismic data,explanation of the fault is more difficult.Fault zone may be the remaining oil enrichment areas,which created great difficulties for well deployment.2)The resolution of seismic data is low and loss low frequency information,resolution of thick reservoirs have significant limitations.3)Main groups under Dong? groups of underwater distributary channel,Lateral variation vary quickly of reservoir,Part of well seismic reflection characteristics and reservoir relationship is not clear.the 3rd and 4th oil group of Dong? section in LiaoXi near the 1th fault seismic reflection clutter,Poor continuity,therefore,using current seismic reservoir prediction is difficult?According to LD 10-1 Oilfield well to seismic calibration result,interpret and research on the structure of lower Dong ? section,set up the isochronous stratigraphic framework on the base of structure research,,analyze drilling results and seismic reflection characteristic of the target zone,study on appropriate seismic reservoir prediction method,summarize applicable reservoir description technique and method system.According to the reservoir characteristics of the target zone and seismic resolution,well to seismic integration to select the appropriate research scale,under the guidance of understanding the geologic model,fine reservoir prediction,research reservoir distribution pattern between different wells,try to distinguish the single sand body,guide the next field adjustment plan research.
