微地震剖面对比优选激发参数的试验方法

Test Method to Select Shooting Parameters by Comparison of Microseismic Sections

随着地震勘探技术的进步,三维地震勘探已成为地震勘探的常规手段。为获取更优的激发参数,跳出传统思维定势,提出了一种新的地震采集激发参数的确定试验方法-微剖面对比法。微剖面对比法通过单一参数微地震数据叠加剖面对比和单一参数微型数据叠加剖面相减对比来达到优选激发参数的目的,适用于目的层浅、信噪比低的地区。

With the progress of seismic exploration technology,three-dimensional seismic exploration has become a conventional seismic surveying method.To get better shooting parameters,this paper,stepping out from traditional thinking set,presents a new test method called as micro section correlation to determine seismic shooting parameters.This method can help to select shooting parameters by comparison of single-parameter micro-seismic data stacking section and of single-parameter micro data stacking section subtraction,applicable to the area with shallow target layer and low signal-to-niose ratio.
