盒子波调查技术在六盘山黄土塬区的应用分析
An analysis of applying the box wave survey technology to the Liupan Mountain loess tableland area
摘要
Abstract
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 var⁃iations 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 ex⁃ploration 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.关键词
