摘　　要：海拉尔盆地是一个断陷叠置的复杂盆地,历经五个发育阶段,具有三套烃源岩地层、五套储层。该盆地近地表结构、岩性及速度在纵横向上均复杂多变,且规则干扰较为强烈。为此,基于宽方位角观测系统设计提出"四高、四精确、三小、二中、一宽、三措施"的配套岩性勘探地震采集技术、保真处理及精确成像技术、复杂断陷盆地层序地层学解释技术、精确储层预测技术、岩性圈闭识别与描述技术等组成的海拉尔断陷盆地岩性地震勘探集成技术系列,在海拉尔盆地贝尔凹陷及乌尔逊凹陷的岩性勘探应用中取得了成功,其中据此预测成果部署的希3井和巴X2井均获高产工业油流。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.
