| This thesis mainly concentrates on analysis of relevant seismic data collected in the studied field.It is possible to provide seismic data volume which can proffer exact descriptions for fins structures and to predict conditions with respect to reservoirs.The results show that energy of effective signals is comparatively lower in deeper areas.Besides,the involvement in noise signals mainly includes surface wave,abnormal values,aberrant amplitudes,high-frequency interferences and multiples.In target stratum,relating information of processed section is pretty substantial.Additionally,some other results,such as SNR,resolution rate and wave groups characteristics,can also be achieved to a satisfied level in target stratum.The trend of sandstones development is predicted by employing reservoir inversion techniques.Predictions for thickness of sandstones can be better correspond to that which was obtained when sandstones facing single well drill.Through analyzing sandstones percent contents and thickness charts,as well as seismic attribute,it is likely to certain reservoir sediments in this region is controlled by provenances of which the distribution direction is from north to west.According to these reservoir predictions,well patterns are designed and deployed in a reasonable way.Taking areas where seismic attribute and sand body development are in favorable conditions into accounts in a top priority,and then arranging horizontal well combined with vertical wells of injection-production well space in those areas.Based on the above studies and results,we have augmented technical knowledge for future development of exploiting areas,which can reduce risks during the process. |
