| 摘 要： | 地震资料的质量取决于采集,其主导因素是选择合理的激发层位。山区坡积带地震能量散射严重,激发点须在坡积物下方,地震成井固井困难,药柱不能到位,针对这些实际问题,需要对激发成井钻具进行有效改进,并对观测方法进行优化。

| Abstract: | The seismic data’s quality is decided by gathering rationality and integrity.The main purpose is that choice reasonable excitation position.In mountainous slop-wash zone,scattering of seismic energy is serious,the shotpoint should be underneath the talus,well completion and cementing of earthquake are difficult,and charge pellet cannot arrive at reasonable position,in view of these actual problems,we need to improve well completion drilling tool and optimize the observation method. |
