Paper Abstract

In this paper we report the first stage field test results of a novel DFB fiber laser geophone system in Shengli oilfield. Two distributed feedback (DFB) fiber laser geophones are wavelength multiplexed and the space between them is 50m. The performance of DFB fiber laser geophones are tested by weak seismic signals stimulated by explosions together with conventional 20DX moving-coil geophones. The results show that the DFB fiber laser geophones have highly similarity with conventional geophones and higher bandwidth. The DFB fiber laser geophone system is promising in micro-seismic monitoring of unconventional oil and gas hydraulic fracturing.
