Abstract：In view of multiple issues of prediction and evaluation for fractural dolomite reservoir with more porosity and permeability in Qingxi sag of a basin,the paper carried out study and analysis from the drilling,logging,seismic and geologic aspects,presented a set of technical tools suitable for the study of complex reservoir in the area,mainly including fine structural interpretation,core observation,imaging logging,seismic attributes analysis,seismic waveform analysis,integrative inversion and fractural model-building etc,gaining multiple analyzing graphics including map of fractural distribution in the area,and then carried out prediction of the developing area of fractural reservoir in the region,resulting in good effects.
