摘要

微山湖某采区面积约4.07km2,区内长年积水,个别区域水深达5～6m,地震勘探施工条件复杂。针对该区资料采集的技术难点,其深水区使用专用检波器,并系重物固定到位;激发井位10～12m,采用船载人工钻成孔;观测系统为8线8炮36道中间激发,24次覆盖。资料处理采用折射静校正及分频处理等方法,其资料处理效果满足地质解释的要求。通过属性识别及相干分析等技术手段本区共解释断层49条,陷落柱2个,目前已验证断层2条,两者高度吻合。
A 4.07km2 prospecting area in the Weishan lake is pounding all the year round,water depth in some places can be 5~6m as deep,seismic prospecting condition is complex.In allusion to data acquisition technical difficulty,special hydrophones were used in deep water areas fixed by weights;shotholes distance 10~12m,completed by shipborne hand drilling;field set up was 8 lines 8 shots 36 channels split shooting,24 folds.Refraction static correction and frequency divisional data processes were used,data processing effects can satisfy geological interpretation needs.Through means of attribute identifying and coherent analysis interpreted 49 faults and 2 subsided columns,and two of faults have already proved with closely fitted of both interpretation and reality.
