摘    要:针对准噶尔盆地车排子地区北部油气勘探"探井少、以地震资料为主"的特点,开展了储层地震响应特征研究。分析认为,岩性组合、物性差异和超剥地层结构是影响地震响应的主要因素。采用"优势频率调谐振幅定厚度、地层超剥带勾勒储层边界、特征随机反演描述有效砂体"技术系列进行地层-岩性油气藏的储层预测,结果表明,砂体的预测结果与实钻结果吻合较好,这对认识此类复杂油气藏具有指导意义。

关 键 词:地层-岩性油气藏  地震响应  约束地震反演  地震频谱分析  准噶尔盆地

Abstract:Aiming at the characteristics of oil and gas exploration, which is charaeterized by less exploration wells and is mainly seismic data, in the northern part of Chepaizi north area, we carried on the study of characteristics of seismic response of reservoir. It is believed that the main factors affecting seismic respnnse are lithological assneiation, physical properly difference and superdenuded stratigraphic structure. Predictinn of stratigraphic -lithological hydrocarbon reservoir is tarried out through the use of the techniques of tuning amplitude with dominant frequency to determine the thickness, outlining reservoir boundary of fnrmation with super-denuded zone and describing effective sandbody with characteristic stochastic inversion. The results show that the predicted result of sandbody coincides well with the result of actual drilling, which provides a reference for the identifieation of similar complicated hydrocarbon reservoir.
Keywords:stratigraphic-lithological hydrocarbon reservoirs  seismic response  constrained seismic inversion  seismic frequency spectrum analysis  Junggar Basin
