Abstract:

Many factors result in low degree of exploration and development of deep formation.Reservoir is the main technical bottleneck.So a variety of geophysical researches should be carried out to describe the spatial distribution characteristics of reservoir accurately.Aiming at the problems of prediction in deep reservoir，comprehensive analysis methods and technological processes are established by taking deepwater turbidite fans of Chezhen Sag as an example，in which，lithologic association of reservoir is taken as a starting point to determine the dominant seismic response and reservoir prediction make based on it.The analysis methods and technical processes bring a good result in oil and gas exploration，and a set of effective technical methods are explored in prediction of deep buried glutenite.

Key words: Jiyang Sag, turbidite fan, lithological association, seismic response, reservoir prediction, technological processes
