摘要
山地地震勘查的表层调查工作非常重要,其准确性影响到井深设计的合理性和静校正结果的正确性,进而关系到地震剖面的质量,因此应使用准确性更高的井中激发、地面接收的微测井方法。通过兴城地质走廊带二维地震勘查的施工实例,分析了山地微测井生产的技术难点,研究和总结了一系列可行性和可操作性较高的方法和措施,从实际结果来看效果良好并可广泛运用和推广。
During a seismic survey in mountains, a surface investigation is very important and its accuracy can influence on the validity of both well-depth design and static correction, further affecting the quality of seismic profile. So, with higher accuracy, such microlog methods as shooting in hole and receiving at surface should be used in mountains. Taking a 2D seismic survey in Xingcheng as an example, we analyzed some technological difficulties existing in these methodsand made many flexible measures. A better result has been obtained after their application.
