Abstract: In 2019, micro-seismic data were collected for the first time in a tight conglomerate reservoir in the Ma 131 well area of the Xinjiang Mahu Oil Field using dual-well (horizontal well and vertical well) micro-seismic monitoring.However, only a small number of corresponding micro-seismic events were detected on both arrays using the traditional long-short time window ratio (STA/LTA) algorithm, which could neither carry out simultaneous dual-well localization and moment tensor inversion nor obtain the characteristics of the source mechanism.Therefore, the micro-seismic event detection based on the template matching technique was reprocessed.Many micro-seismic events were detected, and an analysis of dual-well localization and moment tensor inversion applications was performed to determine the characteristics of the source mechanism and rupture parameters of micro-seismic events.The results showed that the template matching algorithm can identify more valid micro-seismic events in a multi-well array, making moment tensor inversion possible.In the dense conglomerate reservoir of the Ma 131 well area, where natural fractures are not developed, hydraulic fractures have multiple orientations and can form a complex fracture network.The optimal fracturing fluid scale for a single section in T₁b₂ and T₁b₃was approximately 1700m³ and 820m³, respectively, and the contribution of further increasing the fracturing scale to the production decreased.
