摘要
在详细分析辽河探区以往的地震资料品质和地震采集方法基础上,结合辽河盆地特殊的地震地质条件,通过理论分析、野外试验和实际资料采集,深入探讨了精细三维地震采集中几项实用技术,如优化观测系统及其参数、最佳激发参数优选和精选检波组合。这些技术的成功应用,极大地提高了地震资料的品质,满足了精细地震勘探阶段地质目标对地震采集资料的要求。
Some practical technologies for fine 3D seismic acquisition,such as the optimization of geometry for target layer and the choice of source parameter and geophone array,were studied in detail in this paper by means of theoretical analysis,field test and seismic acquisition on the basis of analyzing available seismic data and previous seismic acquisition methods and considering special seismic and geological conditions of Liaohe basin.The successful application of these technologies has greatly improved the quality of seismic data and satisfied the requirements of geological objective for seismic data acquisition at the stage of fine seismic exploration.
