Microseismic monitoring is capable of determining locations of waterflood front drive, optimal waterflood direction, waterflood wave, water spread area and etc., and then interpolates fracture patterns, based on microseismic wave occurred from waterflooding. After brief description of principles of passive microseismic monitoring, this paper analyzes results of application of microseismic monitoring on waterflood front at Daqing Oilfield western periphery, in combination of dynamic and static geological information. Field application asserts that microseismic monitoring has good prospects in fracturing studies of low permeable oilfield, and is great importance to improve recovery of low permeable oilfield.
