【摘要】 近年来,随着勘探精度的提高,勘探要求的加强,给地震勘探激发点位与障碍物距离的控制提出了更高的要求,合理地选择井深、药量与安全距离,将很好地平衡安全和勘探质量的关系。本文首先介绍了安全距离影响因素以及地震安全距离理论基础,然后以胶莱地区为例,介绍了胶莱地区近地表条件,并根据建筑物允许的振动安全速度参数,利用实际试验资料统计计算出胶莱地区不同激发介质的相关系数,以及不同药量井深安全距离,应用到实际中,取得了较好的勘探效果。该方法的研究探讨为地表复杂城区地区的施工中井深、药量、安全距离的设计奠定了基础。更多还原

【Abstract】 Recently,along with the improvement of the exploration accuracy and the standard,the criteria of the control over the shot points and the obstacles are becoming higher and higher.Choosing the preferable hole depth,charge size and the safe distance will contribute to the high quality of the seismic exploration.This paper firstly introduces the factors and the theoretical basis of seismic safety distance.Then taking the Jiaolai project as an example,it applies the test statistics to calculating the correlation coefficient of different exciting media and the safe distance of different dynamic and hole depth,which have achieved a good result.The study of this method has laid the foundation for the design of the hole depth,charge size,and the safe distance in the complex ground surface conditions.更多还原
