“…However, in practical engineering, the extension and distribution of fractures in coal reservoirs after SRV are unknown, and it is difficult to judge whether SRV is superior in coal reservoir reconstruction compared to conventional hydraulic fracturing (Zhao et al, 2018;Ren et al, 2019). Currently, microseismic monitoring technology has been developed in the industries of oil and gas reservoirs (He et al, 2019;Kang et al, 2021), mining and geothermal, and is commonly applied in the fields of rock damage and movement, hydraulic fracturing monitoring and ground pressure appearance monitoring (Ry et al, 2019;Li et al, 2022b), which is of great significance to prevent and control coal mine disasters and ensure the safety of mining production (Zhao et al, 2016;Zhao et al, 2023).…”

Hydraulic fracturing is an important technical measure for coalbed methane (CBM) development, and the propagation of fractures in the target coal seam induced by hydraulic fracturing is related to the stimulation performance in CBM recovery. Therefore, effective monitoring of fracture development during reservoir fracturing is critical for CBM engineering. In this paper, the microseismic technology was used to monitor the spatial and temporal characteristics of the fracture extension in the CBM well during hydraulic fracturing in Zhengzhuang Region, Southern Qinshui Basin, China. Based on the microseismic fracture scanning data and imaging processing, the three-dimensional shape of fractures in vertical wells after fracturing can be quantified, and for the vertical well ZHSY-1, the main fracture direction is identified as NE106°, and the fracture length is 426 m, and the fracture area of coal seam is 1.6 × 105 m2. It is found that fracturing does not develop continuously in time and space with fracturing fluid injection, and the fracture regions are scattered throughout the space, and the formation and development of fracture regions are intermittent. After fracturing with a large amount of fracturing fluid injection in Well ZHSY-1, the fracture area has been significantly increased, and the well gas production has been significantly improved, which is confirmed by the field CBM well data. This study provides a field application case for studying the effect of hydraulic fracturing fracture propagation using microseismic technology, which can be used as a reference for fracturing engineering in CBM development.
