| 摘 要： | 根据薄互层地区地质特点,以及所要达到的分辨率的要求,确定了所要保护的主频频率和施工参数。针对影响分辨率的因素,在激发时使用小药量和“钻杆扫描”的方法选择激发深度;在接收时使用中高频检波器、小组合和检波器下井接收的方法,并对它们进行逐一论证,取得了较好的效果。

| Abstract: | Based on the geological characters in thin interbedded area and request of resolution, we determined the primary frequency kept and the acquisition parameters used in our study. According to affecting factors of resolution, we used less charge and selected shot depth through the method of "drilling stem scanning" at shooting; adopted higher frequency geophones with fewer geophones in group and buried in the well at receiving. They have been demonstrated at our experiments and show some better results. |
