摘要
通过对方法可行性试验,确认在滇西第三系盆地中应用浅层地震反射波方法,探查100—400m深度的基底形态、构造及对盖层分层的有效性。试验采用McSEIS-1500地震仪,选择合适的激发条件,根据工作区有效波和干扰波的特点,研究并采取了有效的野外技术措施,达到提高S/N比,突出有效波的目的。
The orientation survey confirmed the effectiveness of shallow seismic reflection method in determination of basement morphology at the depth of 100-400 m, tectonics and overburden zoning in the Tertiary basin in western Yunnan. McSEIS-1500 seismograph is used to study the effective field technology in order to raise S/N ratio and stress effective waves on the basis of the features of effective waves and noise within the working area by selecting suitable excited condition.
