盒子波调查技术在六盘山黄土塬区的应用分析
|
摘要
六盘山盆地被巨厚的黄土所覆盖,是表层和深层双复杂区域。巨厚的黄土和复杂的地形条件使该区干扰波非常发育,严重影响了地震资料的信噪比。为了有效调查该区干扰波发育特征,并进行针对性地压制,通过盒子波调查技术在该区的应用分析,提出了和生产结合进行盒子波调查的有效方式,克服了静校正问题对盒子波调查数据的影响。针对两种地形条件下的盒子波资料,分析了在不同地形和表层条件下干扰波场的变化,认为影响浅层和中深层信噪比的干扰波特征存在差异;并通过组合压噪效果分析,提出对不同深度勘探目标进行针对性压噪的组合接收方式,提高了六盘山地区巨厚黄土塬勘探区目标层采集资料的信噪比。
The Liupan Mountain basin is covered with thick loess,and is hence an area with complex surface bed and deep bed.Great thickness of loess and complex landform result in extremely well-developed interference waves in this area,which seriously affect the signal-to-noise ratio of the seismic data.In order to investigate the development characteristics of the interference waves in this area and conduct effective directed suppression,the authors,through an analysis of the application of the box wave survey technology in this area,put forward an effective way of box wave survey in combination with production,which can overcome the effect of static correlation on the data of box wave survey.In the light of the box wave survey data obtained from two landform conditions,the authors analyzed the variations of the interference field waves under the conditions of different landforms and surface beds,and found that the characteristics of interference waves that affect the shallow beds and the middle-deep beds are somewhat different.Through the analysis of the combined noise-suppressing effects,the authors put forward the combined receiving type for conducting directed noise-suppression suitable for exploration targets in different depths.The results achieved by the authors have improved the signal-to-noise ratio of the data collected from the target bed of the Liupan Mountain great thickness loess tableland area.
