【摘要】 地震沉积学应用于陆相湖盆时,亟待开展技术方法上的探索。分析了90°相位转换技术、地层切片技术和分频解释技术等3项地震沉积学关键技术的局限性,指出90°相位转换需要综合考虑与之相匹配的地质体的厚度和地震数据频率;地层切片可以用于沉积相解释,针对不同的沉积相类型,需采用不同的切片方式;地质体三维可视化雕刻技术应用于地震沉积学解释,可以解决复杂储集层沉积的三维解释难题。更多还原

【Abstract】 Seismic sedimentology is a new research field proposed during studies of the marine strata abroad in recent years,but its applica-tion to continental lake basins is urgently required to explore in technique.This paper analyzes the limitations of such three key techniquesof seismic sedimentology as 90°-phase conversion,strata slicing and frequency decomposition interpretation,and points out that the 90°-phase conversion technique needs comprehensive consideration of the matched geologic body thickness and the frequency components ofseismic data; strata slicing technique can be used for interpretation of sedimentary facies,but need to adopt different ways of slicing,ac-cording to different types of sedimentary facies; 3D visualization sculpture technique of geological body can be applied to seismic sedimen-tology,solving 3D interpretation problem of complex reservoir sediments.更多还原
