摘要(Abstract)：

由于海拉尔盆地中部断陷带三维连片地震资料施工年度跨度大、激发和接收条件差异较大、方位角和面元等采集参数不同,导致区块间能量不均、子波差异、空面元等问题突出。采用微测井约束的连片层析静校正技术、振幅和子波一致性处理技术、五维地震数据规则化技术、井约束的各向异性速度建模技术等多种三维连片地震处理关键技术,确保了区块间能量、子波的一致性,解决了空面元问题,显著改善了连片地震资料品质,使地震剖面断点清晰、层间信息丰富,为地震资料细分层精细解释和扇体识别打下了坚实基础,在此基础上部署的井位见到了较好的油气显示,对其他复杂断陷盆地三维连片处理具有重要的指导意义。
Due to the large annual span of the seismic data operation, large differences in the excitation and reception conditions and different acquisition parameters such as the azimuth, bin and so on in the central fault zone of Hailar Basin, the problems such as uneven energy among the blocks, sub-wave differences, empty bin and so forth are prominent. A variety of key techniques for the seismic processing of the 3 D continuous blocks were adopted, such as the static correcting technique of the continuous lamination with the micro-logging constraints, the consistent processing technique of the amplitude and wavelet, the regularizing technique of the 5 D seismic data and the anisotropic velocity modeling technique by the well constraints. Thus the consistency between the energy and wavelet among the blocks was ensured, the problem of the empty bin was solved, the quality of the continuous seismic data processing was significantly improved, the seismic section breakpoints were made clear and the information between the layers became more rich. In a word, the solid foundation has been laid for the fine stratification interpretation and fan body recognition of the seismic data, and moreover on the basis of the above, much better oil and gas shows have discovered in the arranged well location, and furthermore all the achievements possess important guiding significance for the 3 D continuous processing in other complex fault basins.
