Abstract：The Hailar basin is a complex fault and superimposed basin and experienced five development stages,where there are three sets of strata with hydrocarbon source rock and five sets of reservoir.The basin is characterized by complexity and variability of near-surface,lithology and velocity both in vertical and horizontal direction,which results in stronger regular interference.For that reason,based on the design of wide azimuth geometry,the paper presented a set of lithologic seismic exploration technology,including seismic acquisition technique(for example:more folds,more receiver numbers,denser sampling rate in both time and space;precious measurement,near-surface survey,analysis of attenuation by absorption and design of shooting-well depth;minor bin-size,array and roll-interval;mid-frequency geophone and moderate charge size;wide azimuth;joint array of source and receiver,real-time in-site QC and real-time dynamic environment interference monitoring),hi-fi processing and precious imaging technique,sequential-stratigraphic interpretation technique of complex fault basin,precious reservoir prediction technique and lithologic trap recognition and description technique,which formed integrated technical series of lithologic seismic exploration of Hailar fault basin.The application of the methods achieved success in lithologic exploration of Ber sag and Wuerxun sag in Hailar basin,in which the high-production industrial oil stream has been gained in Xi-3 well and Ba X-2 well that were deployed according to the predicted results by the technology.
