| 摘 要： | 20世纪70年代末期，在黄桥一如皋地区进行了大量的地震勘探和综合研究工作，因受以下因素的制约：①乡镇企业发达，民居密布，不利于地震施工，造成大段丢炮；②激发岩性为流沙，易塌井，能量衰减快，频率低；③低、降速带横向变化大，等等，从而影响了剖面的质量。为此，在黄桥一如皋地区开展了地震宽线、小点距超多道、可变线元方法技术及成井方式、炸药类型对比、表层结构调查等野外数据采集方法试验，进行了野外采集、资料处理和综合解释一体化的系统分析和研究，总结出了一套适合于黄桥一如皋地区特点的勘探方法技术，解决了由于上述因素带来的一系列问题，获得了品质较好的地震资料。

| Abstract: | Extensive seismic exploration has been carried out in Huangqiao-Rugao region at the late 1970s. However, the obtained profiles are poor in quality due to many factors, including that seismic surveys are impeded by dense population, sharp energy attenuation and relatively low frequency caused by shooting in drifting sand and easy-collapsed holes, as well as rapid lateral variations of weathering zone. Many measures or methods are tested in data acquisition, such as broadened line, short group interval and super multi-channel, variable line segment, different shot hole patterns and explosive charges, low velocity layer investigation, etc. Combining with data processing and interpretation, a suite of explora- tion methods has been developed. Desired results have been achieved. |
