Abstract: In order to collect microseismic signals more accurately，ray tracing is used to simulate multi-source
microseismic signals． First，we used the two-point ray tracing method to adjust the initial value，and then the
optimal exit angle and corresponding ray trace are obtained，realizing full-wave ray tracing． Forward modeling of
microseismic signals based on ray tracing can accurately reflect the kinematic characteristics of stratigraphic
structures． It is a rapid and accurate forward modeling of microseismic signals method． By analyzing the regular
of seismic wave propagation，the forward model established can provide some help for signal analysis and
processing，inversion of microseismic data and source localization．

Key words: microseismic exploration, ray tracing method, forward modeling, multiple sources
