对于海上高精度三维地震勘探,双检检波器是将单一的高灵敏度磁电式检波器和海洋压电检波器两种检波器合二为一的检波器组合模式,它在浅海的耦合方式一直是有效地消除多次波,压制虚反射,进而提高地震资料解释精度获取高品质三维资料的关键。笔者研制了多种类型的耦合器,并在埕岛东油田进行耦合器与双检设备捆绑的试验,确定出了最佳的耦合方案,在实际应用中取得了较好的效果。
For high-precision three-dimensional seismic exploration at sea, the double detection geophone is a combination of a single high-sensitivity magnetoelectric detector and a marine piezoelectric geophone. The geophone coupling mode in the shallow sea has been It is the key to effectively eliminate the multiple waves, suppress the virtual reflection, and then improve the accuracy of seismic data interpretation to obtain high-quality 3D data. The author has developed a variety of types of couplers and tested the coupler and double-check equipment in Chengdao East Oilfield to determine the best coupling scheme and achieved good results in practical application.
