| Abstract: | As a new type of fiber optic sensing technology for long-distance, distributed and real-time monitoring, distributed acoustic sensing (DAS) has been a wide concern since its initiation. Compared with the traditional seismic wave sensing system (node array, geophone, seismometer), DAS has the advantages of high spatial sampling density, wide measurement range, and strong environmental adaptability (anti-electromagnetic interference, corrosion resistance, waterproof).Recently, researchers have carried out a large number of exploratory experiments around DAS technology and made important progress in the field of earth exploration.This paper reviews the latest research on the application of DAS technology for earth exploration. Starting from theworking concept of DAS, the basic concept of DAS is elaborated, and the performance of DAS and seismometer is fully compared.And we introduce the applications of DAS in oil and gas exploration, seismic observation, and structural imagingby reviewing several representative experiments. Finally, this paper summarizes the current bottleneck of the earth exploration technological system based on DAS and analyzes the development trends in the future. |
