【摘要】 准确的地震速度求取对于观测系统设计、地下地质目标体的精确定位、构造解释和储层预测等至关重要。在构造成图方面,应建立精细速度场、采用变速成图的方法,提高构造图的精度,为油气勘探提供依据。更多还原

【Abstract】 The exact velocity is vital to layout design,exact orientation of the geologic target underground,structure interpretation and reservoir forecast,etc.In structure mapping,we should establish refined velocity field and apply variable-velocity mapping to improve the precision of the structure map,thus providing a basis for oil-gas exploration.更多还原
