深层是目前天然气勘探的重要领域。深层地震反射资料分辨率、信噪比低是制约进一步提高深层勘探精度 ,加大深层勘探力度的重要因素。根据地震波传播机理 ,利用分数维理论将地震与声波测井资料紧密结合起来 ,开发研制了一套高分辨率处理软件包 ,恢复由于地层吸收等作用而衰减的高频成分 ,反映地下真实结构 ,提高地层分辨能力。汪家屯 -升平及古龙地区大量的地震资料处理及分析表明 ,该软件包是有效的 ,使深层地震反射资料分辨率与信噪比明显提高。
Deep is currently an important area of natural gas exploration. Deep seismic reflection data resolution, low signal-to-noise ratio is to restrict the further improvement of deep exploration accuracy, increase the depth of exploration is an important factor. According to the mechanism of seismic wave propagation, the fractal theory is used to combine the seismic and acoustic logging data. A high-resolution processing software package is developed to recover the high-frequency components that are attenuated due to formation absorption and reflect the true underground structure. Improve stratum resolving power. The large amount of seismic data processing and analysis in Wangjiatun-Shengping and Gulong shows that this software package is effective, and the resolution and signal-to-noise ratio of seismic reflection data in deep layers are obviously improved.
