Abstract:

Exploration and investigation indicate that there is a structure zone of multi-target stratum subtle traps at Markit slope of southwestern Tarim in the recent years,and its main target strata are the Paleogene,the Carboniferous and the Silurian.To realize the evaluation of lithologic reservoir characters as the present research requirement ,amount of 2-D seismic data from different sources,geophones and acquisition are deal t with merging relative preserved amplitude processing and reservoir prediction researchof seismic inversion.In this paper, all of the data in this area are accurately processed with the relative amplitude techniques, such as static correction, pre-stack attenuation, surface consistency processing method.Good effects are proved by theactual processing result and all seismic sections with high consistent.Ov erall corrections for amplitude,time difference,frequency,phase and waveform are achieved.Those new seismic sections have already got the application in subtle traps research.

Key words: condensate gas reservoir, reasonable pressure difference, productivity equation, absolute open flow capaci ty
