Abstract

In order to make the seismic positioning and monitoring system work more effectively, this paper designs four kinds of geophone array methods. By establishing complex geological model and using micro-grid ray tracing, the process that the signal starts from the source location to the seismic geophone arrays is simulated in forward algorithm. In condition of random disturbance, the source location is retrieved by means of inversion algorithm fulfilled by neural network algorithm and genetic algorithm. Finally, on the basis of the analysis of the result and comparison with the true location, the characteristics of every geophone array method are presented. The paper also discusses proper number of geophones in the every array method. Results show that the most accurate, reasonable and effective array method can be selected and the forward and inversion algorithm is also effective.

Keywords: Genetic algorithm, geophone array, seismic positioning and monitoring, source location.
