At the same time, the MEMS geophone can be used to monitor the microseismic event of coal mining, water reservoir and hydraulic fracturing through the research of failure location and the ratio of rock fracture can be predicted by counting numbers of acoustic emission.After spent six months to monitor injecting microseism in Ying 11 block of DongXin field using this system and collect abundant microseismic wave files. The result showed that the orientation of injecting fracture was mainly NE90°to NE125°. The maximum horizontal principal stress directions were mainly distributed in NE90°-NE130°range. Analysis of numerical simulation result of reservoir stress in Ying 11 block showed that the maximum horizontal principal stress directions are approximate east-west in central and western region and approximate NE130°at eastern border.
