Abstract

This paper describes arrival time of microseismic signals, which were obtained from monitoring fracturing and waterfloodand were used to interpolate mechanisms of micro-earthquake and verify reliability of fracturing and waterflood monitoring. It shows that fracture orientation, waterflood front geometry, and microseismic mechanism nodal plane are consistent, and monitoring results are reliable. This study depicts a selfcheck approach to verify dependability of microseismic mapping itself, and it is an important measurement method for fracturing and waterflood projects of deep formations when no alternative verifications are viable.
