| 摘 要： | 单纯水上和陆地三维地震勘探技术已经非常成熟，对于水陆过渡带条件下的三维地震勘探存在诸多困难。笔者在山东微山湖济宁三号井的三维地震勘探中，地表遍布芦苇、鱼塘、沼泽。条件十分复杂。针对这种情况，在激发和接收中采取了特别技术措施，获得了较好的野外采集资料，在处理中采用地表一致性子波反褶积和地表高程校正，最终地震资料既有较高的信噪比又有较好的分辨率，完成了预定的地质任务，为水陆过渡带三维地震勘探积累了成功经验。

| Abstract: | Three-dimension seismic exploration technique has been mature for simple over-water or overland conditions, but does not work well for water-land transitional environment. This paper gave an example of such application to the Jining well No.3, Weishan Lake, Shandong where reeds, fish ponds and marshes are widespread on the ground, making the conditions complicated. For this reason, special technical measures have been taken during inducing and receiving, as a result, good data have been acquired. In processing, surface consistent wavelet deconvolution and surface elevation correction are used, giving rise to seismic data with higher signal-noise ratio and resolution. |
