摘要
为了建立松辽盆地等时地层格架,深入认识松辽盆地地质特征和结构以及油气聚集规律,本文开展了松辽盆地不同工区、不同时期采集的二维和三维地震资料叠前连片处理技术研究.本文针对叠前连片处理过程中不同区块的非一致性,采用了相应的处理方法和手段,使得连片处理后数据的相位达到一致,区块间拼接带的频率、能量(或振幅)变化自然合理.处理后的资料地质现象丰富,地层齐全,具有较高的信噪比和连续性.资料反映的区域构造合理,有利于对松辽盆地区域地质规律进行统一的认识.
Multi-survey ioint processing with 2D and 3D seismic data acquired in different period in different work area is addressed to establish isochronous stratigraphic framework, to better understand SongLiao Basin geological and structure characteristics as well as the law of hydrocarbon accumulation. The process of merging processing for non-compliance of each block, with a corresponding processing method and means of making contiguous data phase, frequency band, energy （or amplitude） among the different blocks in a natural and reasonable way. After processing, the data has rich geological phenomena and complete formation. It has high signal to noise ratio and continuity. The regional structure showed in the data is reasonable, it will help to totally recognize the geological law of the regional geology in SongLiao Basin.
