【摘要】 微测井作为一种传统的,较准确的表层速度结构调查手段,在生产中已得到了实际应用。但微测井布设密度往往有限,使得微测井资料在地震数据处理中有时效果不佳,一个关键因素是在实际应用中,缺少一种评价其分布密度的有效方法。这里将微测井的分布情况与测区地形变化相结合,提出了距离比、积分绝对值比等多参数微测井资料评价方法,为其实际应用提供了一种科学评价的依据。在这些参数较大的区域,如果用微测井资料建立的速度模型应用效果不佳,一种可能的原因就是微测井的密度不足以控制表层结构的复杂变化。更多还原

【Abstract】 Micro-logging is a good traditional approach to survey near surface velocity structure,which has been applied to seismic exploration.But the number of micro-log in survey area is usually more less than the desired,which often leads to that micro-log data can not play a good role for seismic data processing.One of the key causes is lack of the effective method to evaluate whether micro-log is enough or not.This paper proposed a muti-parameters evaluation method for micro-logging data application,such as distance radio and integral values radio,etc.The method offered a scientific evaluation approach for micro-logging data application.In the case where the seismic data processing result is not good and the value of the muti-parameters is much bigger,a possible cause is that the micro-log is not enough to control near surface velocity structure variation.更多还原
