【摘要】 黔南海相沉积地区，在可控震源与炸药震源的地震普查勘探中，地震反射剖面上，出现的振幅异常，有“亮点”、“平点”与”暗点”显示。研究认为：“亮点”可能为油气层的显示；“平点”可能是含气储层与不含气层之间形成的波阻抗界面；“暗点”可能为岩性变化的层间反射。更多还原

【Abstract】 The amplitude anomalies on reflection profile generated from controllably explosive source in southern Guizhou which represents a marine sedimentary environment indicate thebright, faded and darken spots. The inter’Pretation of these spots may imply that there is presence ofoil and gas reservoirs marked by the bright spots. The faded Spots might reflect a wave impedance interface between gas reservoirs and non-gas-bearing beds, whereas the darken spotS reveal the interlayer reflection caused by a shift in lithology.更多还原
