【摘要】 检波距是浅层折射地震勘探中的一个重要参数,检波距的合理选择是资料解释结果可靠性的重要保证。特别是在二元和多元地形条件下的折射地震勘探资料解释中,选择平距或斜距来计算检波距在不同行业和单位是不统一的。这里从理论上探讨了在二元地形条件下,浅层折射地震资料解释中用平距和斜距二种方法计算检波距对表层有效速度的影响和误差大小,明晰了实际工作中二元或多元地形条件下,不同检波距计算方法所引起折射地震勘探资料解释结果的差异和误差大小及其合理性。更多还原

【Abstract】 The detector interval is an important parameter in shallow refraction seismic exploration,its reasonable choice guarantees to reliability of the interpretation results.Especially,in the refraction seismic exploration under duality or multi-cell terrain condition,it is disunity to use actinic interval or slantwise interval in different companies.In this paper,the error and effect to near surface effective velocity caused by selecting actinic interval or slantwise interval based on theory and computing are discussed,and then the issue of the error and rationality of different selection of actinic interval or slantwise interval in the refraction seismic data interpretation with duality or multi-cell terrain condition is opened out.更多还原
