无人机航测技术在复杂地表区地震勘探中的应用

Application of UAV aerial survey technology in seismic exploration in complex area

近些年,随着油田战略规划的转移,勘探目标区域的地表条件越来越复杂,传统的卫星遥感影像分辨率低,实时性差,细节判读难,无法满足复杂地表区地震勘探的要求。基于无人机平台的数字航摄技术能够获取高清晰度和高分辨率的航测影像,具有高效快速,精细准确,作业成本低,适用范围广,生产周期短等优势,在勘探领域的应用越来越广。文章以某勘探区块航测技术的应用为例,通过对无人机航测系统的研究、影响航测精度的关键点分析以及在地震生产中的应用,探索总结一种适合地震勘探项目大面积、大比例尺测图作业的航测解决方案,保证项目提质提效的同时,减少航测成本的投入。

In recent years,with the shift of oilfield strategic planning,the surface conditions of exploration target areas have become more and more complex.Traditional satellite remote sensing images have low resolution,poor real-time performance,and difficulty in interpreting details,which cannot meet the requirements of seismic exploration in complex areas.The digital aerial photography technology based on the UAV platform can obtain high-definition and high-resolution aerial survey images.It has the advantages of high efficiency,fast speed,precision and accuracy,low operating cost,wide application range,and short production cycle.The application in the field of exploration becoming more and more.Taking the application of aerial survey technology in an exploration block as an example,this article explores and summarizes a method suitable for large-area and large-scale seismic exploration projects through the study of drone aerial survey systems,the analysis of key points affecting aerial survey accuracy,and the application in seismic production.The aerial survey solution for scale surveying operations ensures that the project quality and efficiency are improved while reducing the investment in aerial survey costs.
