【摘要】 结合煤田地震勘探特点,以沁水煤田某大型矿井为例,研究地震采集、处理和解释一体化技术思路及实现方法,结果表明:基于时间连续、空间高密度的宽方位规则化数据采集是实现真正三维空间处理的基础;以弯曲射线叠前时间偏移为重点的资料处理技术,是一体化思路的核心,也是确保成果资料具有较高信噪比、分辨率和保真度的关键;在岩性和构造综合解释方面,充分利用相干滤波、谱分解、倾角探测等多地震属性解释特征,可以突出采区构造和微弱岩性异常的细节,从而提高地质成果精度。更多还原

【Abstract】 With a view to coalfield seismic prospecting characteristics,taking a large-scale coalmine in the Qinshui coalfield as an example,studied technological train of thoughts and realization method in seismic data acquisition,processing and interpretation integrated techniques.The result has demonstrated that: on account of time continuous,spatially high density broad azimuth regularized data acquisition is the foundation to realize genuine 3D spatial processing.Taking the turning ray prestack time migration as the emphasized data processing technology is the kernel of integrative ideas,also the key to ensure higher S/N ratio,resolution and fidelity of resulting data.While in lithologic and structural comprehensive interpretation,taking full advantage of coherent filtering,spectral decomposition,and dip angle detection etc.multiple seismic attribute interpretation characteristics can give prominence to details of winning district structures and faint lithologic anomalies,thus to improve geologic result accuracy.更多还原
