摘要/Abstract

摘要： 针对准噶尔盆地中拐凸起上乌尔禾组及风城组地层尖灭线不明确的问题,利用调谐体属性方法,结合地震剖面及钻井资料,刻画了目的层地层尖灭线展布特征。结果表明,在有效频带范围内,上乌尔禾组55 Hz及风城组45 Hz调谐相位属性所识别地层尖灭线更接近真实位置,而超过有效频带范围地层尖灭线精度很难进一步提高;该方法所刻画地层尖灭线的效果明显优于利用瞬时相位余弦、瞬时相位、单频相位等属性的刻画效果。该方法对超覆型及削蚀型地层尖灭线的刻画具有借鉴意义。

关键词: 调谐相位, 地层尖灭线, 有效频带宽度, 离散傅氏变换, 振幅属性, 瞬时相位

Abstract: To address the problem of unclear pinch-out lines in the Upper Wuerhe and Fengcheng Formations at Zhongguai Uplift, Junggar Basin, the distribution characteristics of pinch-out lines of target formation were characterized by the tuner attribute method in combination with seismic profile and drilling data. The results of the study proved that within the effective frequency bandwidth, the pinch-out lines identified by the tuned phase attributes of upper Wuerhe Formation at 55 Hz and Fengcheng Formation at 45 Hz were closer to the real positions, but it is difficult to improve the accuracy of the stratigraphic pinch-out line beyond the effective frequency bandwidth. The effect of this method was obviously better than that of instantaneous phase cosine, instantaneous phase and single-frequency phase, and other attributes. This method has reference significance for the characterization of pin-out lines of overburden and eroded formations.

Key words: tuned phase, stratigraphic pinch-out line, effective frequency bandwidth, discrete Fourier transform, amplitude attribute, instantaneous phase
