【摘要】 本文在对牛庄洼陷地层格架、构造体系和沉积相研究的基础上,从速度研究和层位标定入手,建立了区内地质、地震、测井资料之间的对应关系,并以一系列一维和二维模型研究为理论依据,通过对区内高分辨率剖面的观察和分析,建立了区内不同厚度砂体的地震反射模式,探讨了薄砂体的定性解释,共解释砂体55个。利用厚度波形振幅分析法,对薄砂体的定量解释进行了探索,总结出了薄砂体的综合解释方法。更多还原

【Abstract】 On the basis of studing the stratigraphy framework,structural system and depositional fades in Niuzhuang depression, this paper approaches the seismic velocity and demarcation of reflectors and set up the corresponding relationship among the information of geology, seismology and well logging. By analyzing high resolution seismic section in this area, seismic reflection models of different thickness sandbodies are developed. Qualitative interpretation of thin-sandbody was discussed and 55 sandbodies were interpreted. Quantitative interpretation of thin sandbody was made by analysis of wave shape and amplitude and the combined interpretation method for sandbody was given.更多还原
