【摘要】 在砂、泥岩地层中,地震反射成层性较好,通常利用频谱成像调谐能量相对高来检测储层分布。相反在生物礁、火山口等特殊地质体内部,地震反射杂乱,据此采取逆向思维,利用频谱成像调谐能量低值区的分布,实现对特殊地质体的检测。该方法在多个生物礁、火成岩工区储层预测研究中取得了较好的效果,形成了一套快捷的寻找特殊地质体的思路。更多还原

【Abstract】 In sand and shale interbedding strata,seismic reflection shows good stratification.So the relative high tuning energy in frequency spectrum imaging is often used to identify reservoir distribution. But for reef,volcanic vents and other special geological bodies,seismic reflection is complex.In terms of reverse thinking,the distribution of low tuning energy in spectrum imaging can reveal special geological bodies.The technology is now available and deployable. Good results have been achieved by using the method for predicting reef and igneous reservoirs,which provides a framework and methodology for discovering special geological bodies.更多还原
