Distributed Fiber-Optic Acoustic Seismic Geophone for Petroleum Geology Exploration
In petroleum exploration, a seismic geophone is an indispensable tool. It is primarily used to collect seismic wave data, obtain formation data, and monitor reservoir exploration and fracturing oil recovery technology. This study investigates distributed fiber-optic acoustic sensing (DAS) system and its application in petroleum geology exploration, and deeply analyzes the interferometric demodulation principle, the algorithm, and the parameter test of DAS technology. Furthermore, a ground geophysical prospecting test is conducted, and a clear seismic section image is generated, as well as the performance and the test data of DAS are analyzed in detail.
