榆树林油田地震资料连片处理解释技术的研究与应用
|
摘要
在三维工区连片处理中,通过子波整形、叠前面元内插和均化等处理技术,将不同区块、不同年度、不同面元、不同覆盖次数的三维地震资料重新抽成统一面元的连片地震工区并与二维工区进行拼接,确保拼接处过渡自然;在处理时还重点采用了DMO叠加技术、三维随机噪音衰减技术、地表一致性反褶积与预测反褶积串连、反Q滤波等提高分辨率技术对全区的地震资料进行目标处理,达到了在保真的前提下,提高全区资料的分辨率。同时,采用地震与地质相结合的方法,对成果剖面进行精细解释,从整体上认识榆树林油田的葡、扶、杨油层的构造特征、岩性特征及油气富集规律,从而对榆树林油田的储量未动用区的开发潜力进行分析评价优选。
During joint processing of 3D seismic areas, through wavelet shaping, and prestack bin interpolation and equalization etc. , 3D seismic data from different areas, different periods, different bins, and different fold times were formed for generalized bins connectting with 2D areas to ensure natural transition; to improving resolution based on amplitude fidelity, the target peocess-ing in the whole area was conducted using DMO stack, 3D random noise attenuation, surface-consistent deconvolution and predicting deconvolution combination, and inverse-Q filter etc. . Meantimes, the fine interpretation was conducted using seismic and geology combination method, structural features, lithologic features and oil/gas enrichment rules of Putaohua, Fuyu and Yangdachengzi reservoirs were recognized, then developing potential of undevelop-ing reserve areas in Yushulin Oilfield were analyzed, evaluated and optimized, 8 favorable blocks were optimized for development, 11 wells were designed.
