The technology of observing production performance by using micro-seismic method in swept region is concerned worldwide. The overseas recognition criteria and method of micro-seismic signals are inferred to develop independent observation system and software, which have been successfully used in near 100 wells in Daqing, Huabei, Zhongyuan and Dagang Oilfield. The result of flood front observation is accordant with operation practice according to observation example of Well J344 (injector) in fault-block J11 of Huabei Oilfield. The remaining oil distribution could be estimated at any time by establishing micro-seismic net in early stage of reservoir development. The observation result may be used as a basis for water injection, profile controlling, well pattern layout and adjusting. And the micro-seismic could also be improved to monitor the micro-seismic induced by human activities.
