本文回顾了平面波前法的原理,讨论了平面波前地震剖面的模拟与解释。平面波前时间剖面可用极小点时间剖面来模拟。将中间发炮的共炮点记录中各道叠加就可得到极小点的波至时间。零偏移距的单边放炮记录也可当作中间放炮记录做类似的处理。极小值时间剖面可直接作时深转换。模拟平面波前法除偏移和时深转换外,不涉及速度资料,因为它无需作动校正处理。此法对多次波和面波有较好的压制作用。 This paper reviews the principle of the plane wavefront method and discusses the simulation and interpretation of the plane wavefront seismic section. The plane wavefront time profile can be modeled using a minimum point time profile. Will be shot in the middle of the total shot record in each stack can get the minimum point of the wave to time. Zero-offset unilateral shot recording can also be used as a middle shot record to do a similar treatment. The minimum time profile can be directly converted to time-depth. In addition to offset and time-of-flight conversion, the simulated planar wavefront method does not involve speed data as it does not require corrective action. This method of multiple waves and surface waves have a better suppression.
