【摘要】 山东济宁二号井第十三采区,地表属于典型的湖沼地形,地表条件异常复杂,野外采集难度大。针对这种情况,在野外采集中采取了一些特别措施,如采用无线遥测数字地震仪器,以克服大面积水域布线难的问题;井中炸药激发,以提高激发能量;采用大桶代替泥浆坑、铁管隔离湖水的方法,解决激发深度的问题;在清淤船、公路附近施工,采用加炮、增加接收道数、增加接收线等办法,保证叠加次数不低于24次。由于野外施工措施得当,获得了较好的野外地震记录,保证了地质成果的可靠性。更多还原

【Abstract】 The No.13 winning district,Jining No.2 coalmine,Shandong has typical limnic topography,surface condition is very complex;field data acquisition is very difficult.In allusion to this condition,some special measures have taken in field data acquisition,such as wireless remote controlled digital seismograph is used to overcome difficult wiring on capacious water area;borehole charge shooting to improve shot energy;using large barrel to replace mud pit and iron tube separate lake water to improve shot depth;when operation is near dredgers and highway,shot adding,receiving traces and receiving wires need to be increased to ensure stacking fold not less than 24 folds.Since the proper measures taken in field operation,better field seismic records acquired,and ensured reliability of geological results.更多还原
